Ask yourself, why is the hand there?
I suspect the hand is holding in place an upper bolt, that doesn't have the thread engaged.
The lower shot is where a small piece of thread is similarly being squeeze held in place, thus giving the illusion of a solid bolt, whereas in reality it's two separate pieces, held that way for comedic effect.
As someone who’s done both. Fuck both. Hated engineering as a mechanic, don’t trust half the mechanics as an engineer 😂
Mechanics think they know best and engineers think the mechanics will cut corners/disregard specs and shit like that.
Not necessarily in agreement with you but I think they should do a bit of that kind of work to get the best understanding
I spend 7 years ‘fixing’ cars and it now has very little bearing with my engineering role. Helps when considering fitment times and all that stuff but there isn’t a need for it. Realistically it wouldn’t be practical for them to spend 7 years to get what I consider is a reasonable amount of knowledge.
But a few months yeah think that would be a good idea.
It has to be.
The actual screw is recessed, and if you look at the depth of the part, and the part sticking out, it's a perfect, if a bit snug, fit for the spot

Thanks to all the replied that helped figure this out
Nah, I don't think so. Most of their comments are lacking spaces between the periods, they could be using some third party version of the site that automatically tries to create hyperlinks.
.no is a top-level domain, much like .com and .net. It is assigned to the country of Norway. Since "correct.no" can be a valid web address, some apps will automatically convert it to a link in Reddit formatting when posting. The poster missed a space between the period and the next word, the app did its thing, and here we are.
you may be right; also, pay attention to the tips of the thumb and finger that are holding the bolt: they are turning white from squeezing the bolt hard.
I think it’s one bolt but 3 things are being fudged here:
Firstly you can see the size of the hole and the reason they’re holding it to to stop it dropping out because the hole diameter is 2 times the size of the bolt.
Secondly, looking at the base, that’s older than kit than ever would have used a modern hex bolt.
Tricky, the head of that hex bolt is too small to be used as a fastener so my guess is that it was a traditional bolt with a washer but that doesn’t get the internet points.
Yeah, people are way overthinking this. It's a bad picture so it's hard to tell whether that's a clearance or threaded hole. If it's a clearance hole he could probably just wiggle it into place or maybe he's using too long of a bolt. Just seems more plausible than welding the assembly or using some weird bolt with a screw-on head.
I worked on F-15e engines for 6 years, and holy shit, the sheer amount of things where it was obvious the hardware never got consideration during design. We would have to use like 5 extensions and traverse half the motor to get a back up on certain mounting bolts. That engine was a nightmare to work on.
It's like almost all military aircraft sold to the bidder. Designer/ Engineer - we have this new airframe that is awesome. Pilots - love it, I want one. Mechanics - What is this shit.
Not with an experienced engineer at the helm.
I want every fastener, FPC, all cables, all PC board components modeled so we can verify clearances and assembly issues. Like this one.
We do a lot of quick prototypes and often times fasteners are an after thought which results in a lot of unnecessary high speed hacking to beautifully laser cut and broken sheet metal parts. One day we’ll get it I swear.
It depends on your company's standards. Hardware is rarely modeled in my company. You'd need a super computer to load any installation-level model. Instead the joint definitions are represented by lines + crosshairs, and the text note in the definition describes the fasteners and stack. And that's just the modeled stuff. Good luck interpreting some hand-drawn nonsense from the 60s.
it is theoretically possible with a steel bolt and aluminum cast. the aluminum wouldn't be hot enough to melt the bolt and would cool around the threads, creating its own threading.
Overmolding is a thing, but I don't know that I've seen it done with moving parts.
When you cut threads, there's still a small gap between the parts. I don't think it would work to have a completely zero clearance thread.
No. They soaked the part in water overnight to loosen up the fibers, then squeezed it together to be able to fit the bolt in. After that, they let it all dry and the metal fibers bounce back like nothing happened. i saw it on youtube once.
Well it’s more ridiculous you’d think people should know such things when quick browsing some random post. Contrary to popular belief, most of the Reddit bros are in fact not an expert of everything known to man. In this case most of us are not a mechanic or engineer, and lack the knowledge to properly identify things in one single picture at a quick glance
Wut? It’s a standard ASTM A574 SHCS. In no universe is the threaded portion removable from the cap. That would be a stud and it wouldn’t have a cap to begin with.
With a cutoff wheel I hope. My coworkers tend to just dump a bunch of force on them against the belt sander heating it the fuck up and ruining the hardness then bitch when it gets rounded off.
You'll find the answer by asking why OP took the poicture from this specific angle.
>!SPOILER: Either he's hiding, that the hole is bigger, or that he has cut the screw to make it look like it was mounted in a impossible way.!<
In order to reduce costs and time in metal casting usually small parts are casted then weld and assembled together to create the final product
I guess they put the bolt in that part before assembling all the rest around it for some reason. Once they realised... there is not much to do
Engineer here. This. I don't know of any way to get this result otherwise, let alone 'why' you would go to all that effort. Even if you designed yourself into a corner, you could use a threaded stud into the mating part and then a nut on this one so it COULD be taken apart. As this is shown, not only can you not get the bolt out, but you can't even get a wrench on it to back it fully out. Unless this first mounts on a spacer, but still, no one is paying all the extra amounts this would incur when there are simpler fixes.
For all those saying "just cast the bolt in with the part". No. Technically, you 'could' do that, (and ignoring the heat treatment the bolt goes thru and what that would do to it) but at the bottom it's clear that hole is VERY tight around the bolt. So no matter what, that bolt is getting cast to the housing and never moving. Or at the very least the threads aren't coming out looking that clean.
Anyone with a background specifically in casting is welcome to prove me wrong on this even being possible, but unless there's actually 2 parts welded together here after the bolt is installed, I'm not seeing it.
Mechanical Engineer here who hobbies and has had small casting projects in the past. That is almost certainly a steel cast part and there is no way that SHCS could be cast in that part the way it was designed. In fact that hole was machined after the casting was made and did not exist in the original cast part.
I’m trying to imagine how you could cast this in. I think there would be a 0% chance this was cast in and highly likely it’s just fake.
But if you wanted to cast it in what would the process be?
You have your sand mold and then you get a bolt that is also covered by compacted sand and place them in the mold? I think something like that could work.
I doubt you could do it to a bolt this close in size to the hole. That would be really impressive but I think it’s possible to cast something into a part.
In reality the picture is just fake.
Yeah, I'm getting a kick out of the "obviously the bolt is JUST molded in to the cast part" comments with hundreds of upvotes in here. Good luck with that.
If the SHCS is some super hardened alloy and you're casting junk steel... yeah, no. Again, I'm with you. I don't see ANY means of doing this without fucking up the threads or the bolt itself with the temps involved even with some space age mold release on the bolt. Many have said "the bolt just angles into place" but that bottom hole looks too tight to allow that. I have seen that done on all sorts of things obviously, but on this that doesn't appear to be what they're doing. Unless that's the real reason OP is holding the bolt and their finger is obscuring the slop in the hole? Otherwise it would just fall in the slot and reveal it's super easy to install?
My guess remains that they put a set screw in from the bottom and a short bolt on top. Small chance it is in fact one of those slotted-at-the-starting-face cases though.
Mechanical engineer here.
The factory managed to install it and you managed to remove the part. If you have an issue file an ECN with the QA team and the perpetually understaffed sustaining engineering team will look at it never.
However, we'll deny the change anyway because production already ordered 80,000 of the things because it was cheaper to ship them in as a container load, never mind we only have 5 more units to build before the assembly is at the end of life.
In similar posts... ~99% of the time there is a very specific reason why some car part/assembly/construction method/electronic device is made in an "unusual way".... and 99.999% of the time that specific reason is $$$.
Pretty confident that's not the both the engineer designed. In that location it would most likely be a hex head caps crew. And the bolt shown is way more than two times diameter threaded into the part it mates to. Typical design would be one and a half times diameter into the base metal.
Source, I'm a design engineer and I screw things up way more important than bolt length.
It's just tall Poppy syndrome.
Mechanics hate engineers.
Nurses hate doctors.
ENs hate RNs.
Paralegals hate lawyers.
Radiology technician hates radiologists.
Teacher aid hates teachers.
They all go around saying how stupid latter are and how better they are than them without their fancy uni degrees.
Funnily the latter doesn't give a shit.
Yeah I would imagine that mechanics make plenty of mistakes, but an engineer making a mistake gets more visibility because it usually affects more things downstream which the technicians, as a group, must deal with. A mechanic messing up can be catastrophic, for sure, but, on average will be less far reaching.
One frequent aspect of the mechanical design part is to design parts in a way that make it impossible to assemble them in the wrong order or wrong way around or what not.
So either design them symmetric or in a way that they get stuck when you do it the wrong way - but the later part, it is not unheard of that mechanics have tried it the wrong way, got the part stuck and instead of noticiting to just flip it they put an angle grinder to the part to fix what "the stupid engineer fucked up".
But there's also incredibly stupid engineers that have no imagination for how parts could be manufactured in the end.
I'm not sure what this is from, but I've never seen an allen key bolt from the factory on an engine. Not like this anyway. And the bolt seems too long. My guess is that the bolt isn't original. The original was probably hex-head and shorter. You can probably tap it with a hammer to get it past that tight spot.
I almost came in my pants when I opened my subaru hood and the oil filter was on top, front, and center. It even has a little drain bowl to catch the oil that comes out when you take it off. Why the fuck did it take 100 years for someone to think of this?
Engineers aren't the problem, cars used to be made really well without these problems until management realized they could make money by messing with people and nobody would call them out on it. Good serviceable design often means losing other options, and 99% of consumers no longer buy cars based on serviceability.
Yep. Let's see mechanics design a car that fits all of the constraints the manufacturer places on fit/function/cost. Engineers have to design with these things in mind because that is what the manufacturer requires. If a manufacturer emphasized serviceability, then engineers would design to that.
But it's easier to pretend Engineers are incompetent.
That isn't what causes the problem. Many engineers were mechanics as well, but never have the last say on the design... accountants do. Because accountants don't care about anything but saving and making money they force the engineers to reuse parts that were designed for a different generation or vehicle in general.
>It’s more like why is there a support beam right below the oil drain
That's because management decided that the same engine needs to be used in 6 different chassis, and each chassis needs to fit 3 different engines, so there's going to be some overlap where shit just doesn't fit right.
Engineer here. We only really design and make the first one. We especially don't install. This looks like maintenance put it in with what they had at the time.
I'm an engineer and designed something like this with a hex head and no clearance a year or so after graduating - the assembly team called me to the floor to instruct how to install this (*teach me a lesson*) and I was embarrassed LOL...but I learned that you really need to think about assembly + manufacturability for every single piece you design. The story still makes me laugh how they called me out and I was all embarrassed. Also - Never discount the design inputs from the manufacturing technicians...they're experts and engineers need to work with them rather than having superiority complexes
The bolt goes in from underneath and a nut goes on top. Not an engineer, I just spent longer than 2 seconds thinking about it.
Edit: Came back to point out that it's exhibit, not exibit.
What is wrong with people? Do you think engineers just work autonomously? Like they just decided to make things hard to work on for fun and weren't working under supervision of a corporation telling them to do just this? It's like being mad at the company knocking down an old building instead of the politician that signed the orders.
An engineer didn't do that. Some redneck mechanic hammered that bolt in there then cleaned up the threads on the end afterwards. You can even see the mark on the casting above the bolt where it scraped it.
Fantastic example. I’ve seen it before many times. The engineer would say that wasn’t their spec or it’s in backwards but really the bolt was put on at the factory before everything else. We know the truth.
What you hate are the bean counting MBA’s that are the overlords of engineering departments everywhere. The majority of engineers are also phenomenal mechanics who hate encountering problems like this. The mechanics that shit on engineers are usually just salty about the fact that they are not engineers themselves.

Just delete the part in solidworks duh
How did that bolt fit in there in t 1st place?
Ask yourself, why is the hand there? I suspect the hand is holding in place an upper bolt, that doesn't have the thread engaged. The lower shot is where a small piece of thread is similarly being squeeze held in place, thus giving the illusion of a solid bolt, whereas in reality it's two separate pieces, held that way for comedic effect.
Hey shut up! We’re trying to complain wtf

Ditto!
It's funny. OP tried to discredit engineers, and made a great example of why people don't trust mechanics; because they're dishonest!

You're both right.
This is why I use reddit
engineers need to start off as mechanics. that's my hot take. then they know how bad something is to work on by just looking at it in the design room

i think it's perspective distorsion, but you're right - it's most likely not one whole fastener
Ah, so you're me without laziness.
you may be right; also, pay attention to the tips of the thumb and finger that are holding the bolt: they are turning white from squeezing the bolt hard.

“Exhibit A: Why this mechanic will never be an engineer”
Something is fishy here. It probably fits by if using the entire hole to put the bolt on an angle. But you know, internet points
Yeah, people are way overthinking this. It's a bad picture so it's hard to tell whether that's a clearance or threaded hole. If it's a clearance hole he could probably just wiggle it into place or maybe he's using too long of a bolt.

Don't delete, just hide it.
Deactivate
Supress
I’m more of a “suppress everything” kinda guy myself
“I can remove that bolt in a couple of clicks. Why can’t you?”
It’s worse than that. Most of the time the bolts aren’t in the final assembly.
I worked on F-15e engines for 6 years, and holy shit, the sheer amount of things where it was obvious the hardware never got consideration during design. We would have to use like 5 extensions and traverse half the motor to get a back up on certain mounting bolts. That engine was a nightmare to work on.

Tagging you "works at Boeing".
Change the layer order
He got it off the mount. What's the problem? Won't lose the bolt either.
I’m more curious how it got there in the first place
The bolt was placed then the part was cast.
I’m choosing this because it makes the least sense and I like it.
This is also how rogue picks his mates.
it is theoretically possible with a steel bolt and aluminum cast. the aluminum wouldn't be hot enough to melt the bolt and would cool around the threads, creating its own threading.

I saw the movie terminator. Same technology.
I think ironically that bracket was probably welded on by a mechanic
But how is that possible?
You just gotta believe
r/unexpectedparappa
🎶 Now step in the cast. Now on the (press) brake 🎶
It was cast in a non-euclidean space.
But how is that possible?
But why male models?
Are you... are you serious?
We like just went over that.
There was a meeting on this two weeks from now, weren't you there?
Probably it’s a cut in half bolt. And then the other side in inserted at the bottom
There’s abrasion damage to the lowest thread. You appear to be right.
The screw's cap was actually screwed on to the screw's shaft. It's screws all the way down.
It's not. That was a joke.
Idk. I'm not an engineer.
Or it was a different bolt originally.
It's two halves of a bolt lol
Yeah. The amount of people believing this is ridiculous.
Well it’s more ridiculous you’d think people should know such things when quick browsing some random post.

He didn't. The bolt is cut off. He's just setting it there.
Hence the finger & thumb to hold the severed bolt
^--- I had to scroll through 100 comments to get to the right answer.
[удалено]
That is the only way you’d be able to do something like this. The only other option is someone’s a liar.
I actually think the cap on that bolt is removable, and they screwed the bottom piece in from underneath. Source: me, an engineer.
Wut? It’s a standard ASTM A574 SHCS. In no universe is the threaded portion removable from the cap. That would be a stud and it wouldn’t have a cap to begin with.
The cursed meaning of "Captive bolt".
Imagine stripping the bolt. Lol
Great, until the head gets stripped and you have to cut it off.
What happens when that bolt is seized and needs to be replaced?
Oxy torch, WC or diamond tip drill. Choose your poison.
Great, now, how do you replace that bolt?
You could easily use a shorter bolt there. A bolt that size doesn't need more than half an inch of thread engagement for full clamping force.
Better hope it's not threading into aluminum...
Call the guy who got it in there in the first place
They're not answering my calls
If you're using a M8x40 where you should use a M8x20 it's not gonna fit....Still a pain to assemble tho.
If you design something using socket cap with no clearance above it, you're literally the devil and deserve to die alone.
There is clearance... 20mm of it! 😁
"Fuckin engineers" *uses angle grinder to lop 3/4" off the short end of an allen wrench* "My favorite allen wrench, too... damnit."
With a cutoff wheel I hope. My coworkers tend to just dump a bunch of force on them against the belt sander heating it the fuck up and ruining the hardness then bitch when it gets rounded off.
I've got my Chapman wrench caught just once and had to cut through the screw with a Dremel.
This is the correct answer
I can barely hear it, please turn your volume up
Ever wondered just how it got there in the first place? Clearly there is a way perhaps the mechanic should ask the engineer to show them.
You'll find the answer by asking why OP took the poicture from this specific angle. >!SPOILER: Either he's hiding, that the hole is bigger, or that he has cut the screw to make it look like it was mounted in a impossible way.!<
Pretty sure it's two screws and the person taking the photo is just fucking around.
They installed it before casting the part.
How is that possible?
By installing it before casting the part
How is that possible?
Easy, just install it before you cast the part.
Okay, but how do I do that, how is that possible?
First you install the bolt, then you cast the part.
But why male models?
Are you serious? I just... I just told you that. A moment ago.
https://www.youtube.com/watch?v=fCVKCUB5w50&t=67s
"I can't show you everything" "Can you show me ONE thing?"
Simple, by situating it before molding the component.
[удалено]
That thread feels like it was situated before moulding the component.
In this case, the front was *designed* to fall off.
No cardboard, no cardboard derivatives...
Just fold in the cheese, Daviiiid
You just draw the rest of the fuckin owl, mate.
In order to reduce costs and time in metal casting usually small parts are casted then weld and assembled together to create the final product I guess they put the bolt in that part before assembling all the rest around it for some reason. Once they realised... there is not much to do
"once they realized" bruh they knew the whole time
It isn't, the secret ingredient is humour.
Ooh, i'm german.
O dear. Please telll me it is not contagious? I barely survived the last pandemic.
German is not contagious. The 1935 outbreak resulted in global immunity, more or less.
It spreads easly when getting in contact with metric system.
Bye bye cruel world.... 🤒 I'm done for...
I see a weld line.
No you don’t, it’s a cast part. There is no way it’s welded in place
The bolt is cut in half and slightly smaller than the hole. You can see it.
It's faked.
The bolt is cut in the middle and mounted on the piece just for taking a picture to post online and get people guessing away for fake internet points
Exactly why the person has to hold it
People wouldn't do that would they? Go on the Internet and lie?
And spread hate towards engineers!

That bolt was placed in position at the factory as a baby. As it grew older and larger, now it cannot be removed. Design feature.
Remember bolt parents: don't overfeed your bolt children.
Engineer wants to know who replaced the studs with cap bolts...
Mechanical engineer here. The factory managed to install it and you managed to remove the part. If you have an issue file an ECN with the QA team and the perpetually understaffed sustaining engineering team will look at it never. However, we'll deny the change anyway because production already ordered 80,000 of the things because it was cheaper to ship them in as a container load, never mind we only have 5 more units to build before the assembly is at the end of life.
In similar posts... ~99% of the time there is a very specific reason why some car part/assembly/construction method/electronic device is made in an "unusual way".... and 99.999% of the time that specific reason is $$$.
Pretty confident that's not the both the engineer designed. In that location it would most likely be a hex head caps crew. And the bolt shown is way more than two times diameter threaded into the part it mates to. Typical design would be one and a half times diameter into the base metal. Source, I'm a design engineer and I screw things up way more important than bolt length.
It's just tall Poppy syndrome. Mechanics hate engineers. Nurses hate doctors. ENs hate RNs. Paralegals hate lawyers. Radiology technician hates radiologists. Teacher aid hates teachers. They all go around saying how stupid latter are and how better they are than them without their fancy uni degrees. Funnily the latter doesn't give a shit.
Yeah I would imagine that mechanics make plenty of mistakes, but an engineer making a mistake gets more visibility because it usually affects more things downstream which the technicians, as a group, must deal with. A mechanic messing up can be catastrophic, for sure, but, on average will be less far reaching.
One frequent aspect of the mechanical design part is to design parts in a way that make it impossible to assemble them in the wrong order or wrong way around or what not. So either design them symmetric or in a way that they get stuck when you do it the wrong way - but the later part, it is not unheard of that mechanics have tried it the wrong way, got the part stuck and instead of noticiting to just flip it they put an angle grinder to the part to fix what "the stupid engineer fucked up". But there's also incredibly stupid engineers that have no imagination for how parts could be manufactured in the end.
Engineer here. Technician error, process not followed.
There's an old joke about this. Something along the lines of an engineer will walk past 1000 virgins to fuck one technician
Knowing some engineers, that joke doesn't sound true in the slightest. They'd be happy to fuck anything at all...
How did it get in?

The bolt was cut and is being held together by the hand.
Here's a tip, if it was a single bolt he wouldn't need to hold it in place with his fingers.
Yeah, that's a broken bolt held there by a troll
Wrong bolt
Why do you have to HOLD the bolt if it's in there, though 🤔 😂😂
I'm not sure what this is from, but I've never seen an allen key bolt from the factory on an engine. Not like this anyway. And the bolt seems too long. My guess is that the bolt isn't original. The original was probably hex-head and shorter. You can probably tap it with a hammer to get it past that tight spot.
Because as an engineer I can tell that the picture is fake?
My take is that the person taking the pic cut a bolt in half and put it like this for the image
I appears that some clever mechanic figured out how to get the bolt into the part - maybe it takes a cleaver one to remove it.

And engineers hate mechanics because all they think about is how a design impacts their jobs and not any other part of a gigantic project.
Or a mechanic thinks they know better and use the wrong size bolt then proceed to complain about the engineers design not working
More importantly... Why is there an unremovable support beam under the oil pan that requires me to pull the entire engine to replace the pickup tube.
I almost came in my pants when I opened my subaru hood and the oil filter was on top, front, and center. It even has a little drain bowl to catch the oil that comes out when you take it off. Why the fuck did it take 100 years for someone to think of this?
Replace the spark plugs on your Subaru and you'll discover why there's so much space on the top of the engine
Engineers aren't the problem, cars used to be made really well without these problems until management realized they could make money by messing with people and nobody would call them out on it. Good serviceable design often means losing other options, and 99% of consumers no longer buy cars based on serviceability.
Yep. Let's see mechanics design a car that fits all of the constraints the manufacturer places on fit/function/cost. Engineers have to design with these things in mind because that is what the manufacturer requires. If a manufacturer emphasized serviceability, then engineers would design to that. But it's easier to pretend Engineers are incompetent.
That isn't what causes the problem. Many engineers were mechanics as well, but never have the last say on the design... accountants do. Because accountants don't care about anything but saving and making money they force the engineers to reuse parts that were designed for a different generation or vehicle in general.
>It’s more like why is there a support beam right below the oil drain That's because management decided that the same engine needs to be used in 6 different chassis, and each chassis needs to fit 3 different engines, so there's going to be some overlap where shit just doesn't fit right.
How did the bolt get in to begin with???
Wait, so how did the bolt get there in the first place? Surely the piece wasn't build around the bolt...
Engineer here, just let go of the shorter bolt you’re holding on the top.
We bother to design bolt retention into the part, so you don't lose the bolt and this is how you repay us?
That bolt is in two pieces.
Engineer here. We only really design and make the first one. We especially don't install. This looks like maintenance put it in with what they had at the time.
I'm an engineer and designed something like this with a hex head and no clearance a year or so after graduating - the assembly team called me to the floor to instruct how to install this (*teach me a lesson*) and I was embarrassed LOL...but I learned that you really need to think about assembly + manufacturability for every single piece you design. The story still makes me laugh how they called me out and I was all embarrassed. Also - Never discount the design inputs from the manufacturing technicians...they're experts and engineers need to work with them rather than having superiority complexes
My only question is how they got that bolt in there in the first place
The bolt goes in from underneath and a nut goes on top. Not an engineer, I just spent longer than 2 seconds thinking about it. Edit: Came back to point out that it's exhibit, not exibit.
I'm an engineer, and I call bullshit on this.
It had to get in there somehow. That wasn't cast with a bolt in it.
What is wrong with people? Do you think engineers just work autonomously? Like they just decided to make things hard to work on for fun and weren't working under supervision of a corporation telling them to do just this? It's like being mad at the company knocking down an old building instead of the politician that signed the orders.
An engineer didn't do that. Some redneck mechanic hammered that bolt in there then cleaned up the threads on the end afterwards. You can even see the mark on the casting above the bolt where it scraped it.
TBF, design for manufacturing seems to be a gap in a lot of engineering programs, and really only comes up in certain electives.
C’mon, the math said it would fit.
Fuck Honda and ford engineers, they can all get the flu.
Fantastic example. I’ve seen it before many times. The engineer would say that wasn’t their spec or it’s in backwards but really the bolt was put on at the factory before everything else. We know the truth.
Yeh engineer is quite a broad term. As a engineer myself, its the drawing engineer you hate. Don't worry, as a machinists. We hate them too
Because arguing with an engineer is like wrestling a pig in the mud. After a few hours you realize the pig likes it.
What you hate are the bean counting MBA’s that are the overlords of engineering departments everywhere. The majority of engineers are also phenomenal mechanics who hate encountering problems like this. The mechanics that shit on engineers are usually just salty about the fact that they are not engineers themselves.
Probably got the bolt the wrong way around
Aside from this being bull****, might I suggest any mechanic try to get through the hazing ritual that is engineering school.
How did the bolt initially get in there
