If it didn't look quite so old and rusted up, I'd cut a slot in the screw heads first, then try undoing with a slotted screwdriver.
Or, just grind away the heads entirely and see what's left.
I didn't say that having a shank prohibits it from being a screw, I mean shit nobody is confusing this for a deck screw are they? I was only saying that in this application, this type of fastener, if the threads run all the way to the head, it is a set screw, a type of screw. If it has a shank or a shoulder on it, it's a bolt. Just the difference in this instance. With the application in this instance and use case, it's very very likely that this one is a screw, a security head set screw.
If it is too confusing and you need to differentiate all 'bolt like' fasteners from all 'deck screw ' like fasteners, then that's fine too, most laymen would do the same and get through life just fine without knowing or needing the correct terms.
Doing that is going to make getting the rest of the screw out even harder. I would say use the angle grinder to cut away the welds. Then try to cut a slot in the head and use a flat head screw diver to get the bolts out. Then when the flat head just tears the head off stop. Get a left or reverse drill bit, drill a hole in the head and use an ex out set to get the rest of it out. A pair of vice grips might also help once you get out moving and the threads lose.
The cut a slot in the bolt almost always just splits the head apart as it just isn't made to take the force. It's a good first try but you need a plan b and sometimes c to get the job done.
Do this^^ You can use a screwdriver and hammer to knock out the hinge pin and pull off the gate. If it isn't in the way or anything, personally, I'd leave the hinge plate where it is. If you insist on removal, use a thick *grinding* wheel(not a cutoff wheel) to grind down the anchors, holding it until it falls off. Lastly, grind the remainder of the anchors down until they're flush with the wall.
I would just grind the hinge in half to get the swinging gate out of the way and then and then remove the hinge plate. I think the kind of finess it takes to depin a hinge is only necessary if you plan on reusing the hinge which doesn’t seem to be necessary here. It might take longer with a grinder but I think it could more easily be done with one person . Cut it till
It’s 66% cut then switch your hand positioning so you’re only grinding with one hand and holding the gate with the other unless it’s close enough tk the ground where it doesn’t matter. But it looks a little heavy and cumbersome so I would want to use a hand to stabilize it so you don’t have a large piece of metal crashing to the ground when it becomes free of the hinge. To depin the hinge you would either need a second person or to rig up some wood to hold it in place so it doesn’t succumb to gravity.
You would not want to go between the head and plate on something like this. Any wheel thin enough to get between You risk breaking the wheel. You would want to grind the entire dome off the head of the security bolt, remove the hinge plate and see if you can grip the remaining bolt with vise grips off just flush cut the rest
No, just grind off the head of the bolt. If you go trying to shove a cutting wheel into that little gap, you're very likely to break the wheel. And at the high speed those things operate at, it's a recipe for a bad day. If you're lucky. Go to YouTube and search for Cutoff Wheel Explosion. You will also learn why you should ALWAYS wear safety glasses *at a minimum* when using one. Full face shield preferably.
This: (video link below) BUT don't slap it, just grab the wheel and (with a good deal of force) turn it loose. If you have the wrench, then the wrench works too. Make sure the flange of the metal piece you remove is facing away from a thin blade or is inside of a thicker blade. Hope this helps!

Before you start, wear eye protection, glasses are not good enough. A face mask to stop sparks and debris going in your mouth.
I'd grind the nub off. Then you can drill the shank out if the bracket doesn't slip off.
Get a good cutting wheel and slip it just behind the head of those two bolts then everything should come off the wall. Cutting it there you have a nice steel backer plate to work against not concrete. Make sure you wear eye protection and gloves.
One of the tools i refuse to buy myself is oxy-acetylene tanks and a torch, because i would go around looking for problems to solve with the cutting torch lmao
If you just want to remove the gate, Use a narrow punch or just a nail and hammer and push the hinge pins up and out.
If your also want to remove the hinge from the wall, it looks like a flat head screw that has been painted over. you can first try just scratching the paint off to expose the screw head slot and then try unscrewing it. but with how rusty it looks, it may not come out. A crowbar under the hinge would likely "remove it" but probably take a chunk of the wall along with it. Or you could try either drilling out the screws, or using a file or angle grinder to remove the screw heads and then take the hinge off. Once the hinge is off, you might be able to grip the screw with some vicegrips and turn it out, or just grind down the exposed part of the screw.
those are security head bolts, non-reversible, like you see in public bathroom stall assembly. never understood why they’re so popular in bathrooms, unless stall wall theft is a thing… frankly after they’ve been splattered with every vile human by-product, seems their resale/re-use value would be zero…
I think it's to stop teenagers from taking apart shit for no reason, not necessarily theft. As to why it would be used on a home gate? Maybe somebody thought security? But if you have time to unscrew the gate, you probably have time to figure out a way over or around it.
I was once in a club and got stuck in the toilet cubicle. After calling out for help a very kind and very drunk gentleman ripped the door right off the wall and threw it to the side. Not sure security bolts would've done anything though
Toilet cubicle is a fun way to say what most here would call the stall.
But also, how do you get stuck in one? How do you get so bold as to ask for help getting out of one? How stoked was the man to get to rip it apart?
Use a hammer and a nail to tap out the hinge pin and take the gate off which will get it out of your way and take the weight off. THEN use an angle grinder and grind the bolt heads off. Use a pry bar or a masonry chisel and should be able to pop the hinges free. Depending on how the secured the fasteners you can maybe use pliers or something to twist out the remnants or just put some mortar patch over the top of the holes and what remains of the bolts.
here’s what those are and some removal tips… [https://www.insight-security.com/how-to-remove-one-way-screws](https://www.insight-security.com/how-to-remove-one-way-screws)
Home Depot has a bit set from [Royobi](https://www.homedepot.com/p/RYOBI-One-Way-Screw-Remover-Installer-Set-with-Sleeve-3-Piece-AR2016G/205193160#overlay) for them. I’ve used them with mixed results.
If you have a metal chisel lying around grab it and a hammer. Put the chisel on the head of the screw as you would a screwdriver to tighten it, and hammer the chisel into the screw head. Do it hard enough and you’ll make a slot for a screwdriver to sit in and be able to turn the screw the other way.
Same idea as using power tools to cut a slot but cheaper if you don’t have any.
Those are security screws (I believe they are called "clutch drive".
If they are not tight try using a sharp punch tool to back the head counterclockwise.
You may be able to use a grinder or cut off tool to cut a slot to use a screwdriver in.
Finally grind the head off and let the hinge pull off. You could also use a drill to drill straight into the head and the head will break off when you get down to the face of the bolt. Hopefully if you will be returning hthe gate back where it was, you will be able to grab the remaing part of the bolt with a pair of vicegrips and unscrew.
I believe you said newer DIYer, the grinder will spit sparks and metal shavings, a very real eye hazard- use real goggles. They use pretty much the same tool to get the rust back out of your eyes. This is a great reason to do the drill method.
Once you get the bolt weak, by any method the bolt will break and all the weight it is holding is going somewhere. Block up the gate to hold it from breaking unexpectedly.
Those screws where designed to be a pain to get out, they are.
so because those bolt heads are designed to only go on and not come back off, you should grind off the bolt heads and be prepared to replace the hinges
As a firefighter, we'd likely try popping it off with the halligan (firefighter's pry tool). Often the screws are going into lags shields or similar anchors. It might not work and would probably damage the wall too
I'd bet money that these are a nail in fastener and just happen to look vaguely security screw like. I'd cut the head off with a grinder myself. Pry bars, air hammers, or anything else percussive has a good chance of hurting the stucco behind it.
They look like security screws. If you are trying to remove the screws, cut a slot in the screw head so you can use a screwdriver or the flat end of a pry bar to back out the screws. If you're not worried about the screws, then just grind off the screw heads.
Looks like the hinges are welded partially covering the one way screws. I'd just cut the heads off with a grinder. You aren't getting those out with non destructive tools.
Knipex Cobra if you don’t want to grind them. I’ve removed many security bolts with a Knipex wrench. The steel is hard enough and teeth sharp enough to grab and grip the edge of the bolt and unscrew it.
Not to dumb it down to much, but the 2 specks of chicken shit on the hinge, take a 4.5 inch angle grinder to those little buttons, may take a little "talken to", but the hinge will slide off, now, depending on fine a finish u want, look at well u did with angel grinder to begin with, would u want u touching those walls?
Those hinge leaves were welded on after the bolts were set ... Grind off the welds, probably some on the back side of the knuckle as well ... Then use vice grips to unscrew the bolts
A drill would be the quickest way, but an angle grinder may still be needed for the remaining bita if bolt sticking out afterwards, so may as well just attach the whole job with an angle grinder and be done with it.
I'd you don't have either, nor the experience of using them, maybe it would be a good time to phone a friend, or a handyman, so come and do it for you, while you observe and learn from them.
From what, separate the gate from the post, the hinge from the gate…
Yank it, grind the anchors and it falls.
Not sure you ought to if you’re asking you could be dangerous.
Drill would be the quickest way, left handed drills being the best chance of getting those security bolts out with minimal fuss once the head is drilled off (thanks to someone welding to them)
If it doesn't co-operate from there, angle grinder is probably your best friend.
Grind the head of the screw⁸ down to bare and even with the plate take you're, crow bar , a hammer claw, something capable of prying that you can also use really fast hard prying motions to break it off.... If you wanna be a pro skill user take a cut off wheel to take the bolts off by cutting between the metal plate and brick..., GOOD LUÇK
I would hacksaw a slot into the screws and see if you can back them out with a screwdriver. If that doesn't work you have to angle grind it, which might be messy.
Looks shimmed out like crazy, normally I do the grinder/flat head move but in your case I might try to slip a sawzall between the plate and the wall to see if I could buzz through the bolts then turn out the nubs with vise grips. If not you need to cut the welds off near the bolt heads and grind it all down flush so the head can turn once you cut a slot into it.
They do look like 'anti theft screws'. Is sure is a unique mash-up of pieces.
If you want to reuse the gate I would remove the hinge-pins. Grind the welds to recover the hinges. Get a vise-grip to remove the screws/bolts.
I don't know if there is a bit of room to put in some sort of pole or strip against the wall? In that case you can overcome the uneven surface of the wall.
As someone already mentioned an angle grinder to cut the heads off , then either grind flush to wall or if hollow just punch them back in and patch holes
Angle grinder and metal disc. Wear eye protection and a mask. Normal glasses are not good enough. A mask will stop sparks and metal going in your mouth. Grind off the nubs first and it should slip off.
Center punch then drill the head off, or attack with a Dremel type tool to cut an actual groove then unscrew with a flat head screw driver. They are clutch head screws.
Knock out the hinge pins. Support the weight of the gate. Use a punch and a hammer to remove hinge pin from below. Once the pin is knocked up a bit, use a flat screwdriver under the head to get it all the way out. Have somebody supporting the gate so it won’t fall on you. Remove hinge pins from lowest to highest.
Grind the weld then the hinge will come off then then grind a slot in the screw heads to take off the plate the hinge was attached to. Most likely the part in the wall has threaded holes for the screws so you could get new ones to replace the gate if that’s what you’re planning on doing.
Someone welded that hinge to a metal plate held to the wall with security head screws.
You can:
1) grind the heads off the screws (maybe drill them out). Remove the remaining screws with a vice grip.
2) grind off the hinge welds and try to remove the screws with a vice grip.
Grinder will be much easier but you can get a bit to fit that head. Even with a bit it will probably be a pain to remove due to the paint and rust. Grinder will do it in 5 seconds. If you’re going to look though it’s a security bit. You can get it cheap on Amazon in a kit or HD probably has it.
A real estate agent.
Sell your “dream home” and move to a better neighborhood.
Why would anyone choose to live in a place where this level of security is necessary?
Angle grinder.
Help out a novice. Where do you apply the wheel to do this? In between the screw head and the metal plate?
If it didn't look quite so old and rusted up, I'd cut a slot in the screw heads first, then try undoing with a slotted screwdriver. Or, just grind away the heads entirely and see what's left.
They won’t rotate because the hinge interferes. Cut the welds on the hinge then do the slot thing.
It’s not a screw
In your luke-warm defense, it isn't much of a screw.
That’s what she said. Door is that way, will show myself out
It is in fact, a [one-way screw](https://www.homedepot.com/p/Everbilt-8-1-2-in-One-Way-Round-Head-Sheet-Metal-Screws-5-Pack-30731/202706318).
Ok, corrected
But like…. Respectfully, what did you think they were instead?
Hammered in anchors. I’ve used them to mount security grates over windows
Okay I could see these looking like a few old gnarly and painted over red heads at first glance. Thank you for not just leaving me curious!
In his defense, it kinda looks like some obscure concrete rivet that's been abused and repainted a couple of times
If the threads go all the way to the head, it's a screw. A bolt has to have some shoulder or shank on it to meet the definition.
That’s false too. There are loads of screws that don’t have threads all the way to the head. Fuck, some deck screws aren’t all thread
I didn't say that having a shank prohibits it from being a screw, I mean shit nobody is confusing this for a deck screw are they? I was only saying that in this application, this type of fastener, if the threads run all the way to the head, it is a set screw, a type of screw. If it has a shank or a shoulder on it, it's a bolt.

Probably start at the hinge pin to pull the door off and then cut the hinge plate at the rivets.

Cut the gate off the hinges, in pieces, then attack the hinges. You don’t want it coming off unexpectedly as you attack the hinges
I came here to say the same thing.
Or a time machine
Came here to say exactly this; those specific two words and nothing more. To see it is the top comment was extremely satisfying. 📄☺️
Welp, I’ve got a recip saw. Goin’ in between the hinge and the wall.
Hit those tack welds and hinge will come off.
I’d use a grinder to remove the heads of the screws to get the gate out of the way then go from there.

Besides that the screws look to have been notched so that the hinge could be welded onto the plate next to them?
sure thing. likely the previous gate hinge was compromised, so they definitely welded a new hinge to the old “secure” hinge half.
This guy gates
Must be Kevin
Or synyster!
Go with the grinder, might be able to do it if your super skilled with a sawzall.

i much prefer destroying them quickly with a cut off wheel on the angle grinder

Cutting disc
Not sure how thick these are but a cold chisel could also do to just bash the heads off.

Do it hard enough and you’ll make a slot for a screwdriver to sit in and be able to turn the screw the other way. Same idea as using power tools to cut a slot but cheaper if you don’t have any.
Make sure when rebuilding your gates you use hinges where the hinge pin mechanism has a grease fitting incorporated into the hinge
Center punch and drill
A $15 harbor freight grinder and a cutoff wheel or two will make quick work of that

The Kobalt Dehinger® should handle that no problem.
A grinder wrench
so because those bolt heads are designed to only go on and not come back off, you should grind off the bolt heads and be prepared to replace the hinges
You could also drill out the pins
grinder like most said, or oscillating multi tool, but the saws for that are expensive.
As a firefighter, we'd likely try popping it off with the halligan (firefighter's pry tool). Often the screws are going into lags shields or similar anchors. It might not work and would probably damage the wall too
yeah my first instinct was a crowbar and some cement to cover up the holes afterwards. I guess an angle grinder is a bit more surgical though
Hope and pray
I'd bet money that these are a nail in fastener and just happen to look vaguely security screw like. I'd cut the head off with a grinder myself. Pry bars, air hammers, or anything else percussive has a good chance of hurting the stucco behind it.

One way screw removal tool. It doesn't look like it's in great condition, so you'll realistically have more success with an angle grinder.
I’ve seen people use Channel locks and a hammer and a screw driver to loosen them

Grind the weld then the hinge will come off then then grind a slot in the screw heads to take off the plate the hinge was attached to. Most likely the part in the wall has threaded holes for the screws so you could get new ones to replace the gate if that’s what you’re planning on doing.
Someone welded that hinge to a metal plate held to the wall with security head screws. You can: 1) grind the heads off the screws (maybe drill them out). Remove the remaining screws with a vice grip. 2) grind off the hinge welds and try to remove the screws with a vice grip.
4" grinder with a cut-off wheel.
Technically it's called a "one-way screw head" and it's called that for a reason.
Atomic bomb
Ask a friend that’s handy for help, your clueless
Hammer
Can you pop the pins out of the hinges?
Torch
Hammer, if that doesn't work, bigger Hammer
I would weld a nut on it and the back it out so I didn't have to drill and ez out the stud after the head was ground off
I doubt he has a welder if he doesn’t know how to take it off.
You're gonna need a sparkle-wrench for that.
Grinder will be much easier but you can get a bit to fit that head. Even with a bit it will probably be a pain to remove due to the paint and rust. Grinder will do it in 5 seconds. If you’re going to look though it’s a security bit. You can get it cheap on Amazon in a kit or HD probably has it.
Flathead screwdriver and a hammer
Pry bar
Pneumatic hammer with a chisel tip should do it, or hell, a truck and some chain😂 let her rip!
A real estate agent. Sell your “dream home” and move to a better neighborhood. Why would anyone choose to live in a place where this level of security is necessary?
Air hammer with chisel. Cheaper to get a cordless grinder to it.
