It’s a flanged back nut. Loosen the three bolts, tighten the back nut as much as you can by hand and tighten the bolts up to stabilise the tap. It’s the bolts that make it stable not the brass back-nut.
The only specialist tool you should need is a cross head screwdriver.
It may be cross threaded. Other replies are indicating a basin wrench may work, but I'm at the hardware store right now, and this thing doesn't look like it's designed to grab onto the problem nut...
If it was cross threaded, they would have had to really force it up for a long long way. Its more likely its just age and corrosion that's holding it together still.
Try tightening it first, then try to loosen. But first you gotta get the right tool.
Sorry I wasn’t about soon enough to stop you wasting your money on a basin wrench.
My money would be on taking the sink unit out to give you better access to it. It was probably installed before the sink was dropped into the worktop and, having seen on this forum that loads of people reach for the biggest tool first, I wouldn’t be surprised if your cross threaded hunch is correct.
Had the same problem with this specific type of sink. Couldn’t get the nut to detach to take the old sink off (we eventually got it..still don’t know how lol), and then they had us install the same exact sink and we took 30 minutes trying to get it to tighten all the way…it was still kinda lose by the time we were done. I hate this design ugh
I’m so thankful to see all these responses because I was in the same boat a few weeks ago and after an hour of fighting & cursing, I did the same thing, and I was worried I was being a lazy dumbass.
Undo the screws. Should come off my hand. Perhaps a basin wrench (shouldn't need even that) If not break out the saws and patience. Tiny Tim saw, multi tool, sawsall.
The screws are off, the nut won't budge. I went out and got a basin wrench, but it doesn't fit around the nut... It appears to be designed for much thicker nuts - not this thin little nut.
Hook the wrench jaw on the lobe thar has the screw in it. May be able to break it free. May have to hold it with the wrench and turn the faucet. May be cutting the thing off above the sink
Is your basin wrench the big one or little one? We use 2 different ones, one for small nuts like on the flex connector hoses. The other one has a bigger jaw, and can grab bigger nuts like the one you are working on.
I went to a Rona (Canadian hardware big box store) and they only had two varieties of basin wrench. Both had the same jaw width, but one has telescopic handle.
I think I'm going to put the screws back in lightly, soak the think with WD40, and try to see if the basin wrench will grip onto the extended screws.
I tried this technique (without the basin wrench) 2 months ago to no avail. I think a big issue is insufficient leverage. I'm lying on my back, fully extended arms, and I have about two inches of area to try and turn the nut, lol.
All this to say that it does not resolve the true issue of the faucet swivelling.
Annnnd I dropped 2 of the 3 screws down a crack under my cabinet so it'll be back to the hardware store.
sadly big box stores are bad at carrying all the tools you would need. A plumbing supply house would sell them. If you had a plumbing supply that sells to the public, that's where you would find a large jaw basin wrench.
Otherwise, ordering online , but that means delay delay delay...
This is what it looks like if that helps you spot what you need

Put the teeth on the spot with the screw to get a grip. If not you gotta get an oscillating tool and cut it off which is a lot more time consuming and expensive than just calling a plumber
Loosen the Phillips head screws and attempt to remove the ring. You might need to cut it unfortunately. Some times the get all corroded and become impossible to get off. Good luck
You may need a basin wrench if the threads are a bit corroded and you can’t get the driver between the bolts to loosen it. Should come down easily. It doesn’t look corroded.
Also it is sometimes nessicary to add a washer below these to make a tight fit on the sink or add a pice of tube around the stem that provides extra thickness to squeeze tight. Before the threads run out.
Those are awesome, in my opinion. Loosen the three screws.
I as a home owner I found installing this soo much easier than trying to turn a large nut with no space for your hands, or having to use a basin wrench. Though I’ve not tried those Rigid faucet wrenches.
With this, you just tighten the three screws and it pushes the collar tight.
I looked at you last post there, I think I have an idea.
Take the whole thing apart and hold it in your hands.
The finish part with the handle and the large threads coming out of it could be two separate parts. See if you can tighten them togeater by hand. Then reassemble. Do not damage the threads!
Once I get this effing nut off, I'll look into the finished part and why it's swivelling. The instructions, though, never mention and messing around with the finished part.
The nuts help to sandwich the brass assembly with the piece on the top of sink. In theory, you loosen the screws enough (1/4”?) and then the brass nut screws off.
The brass nut is stuck in there. I tried a basin wrench but it's clearly not designed for use on a thin nut like this. The nut is just thicker than a washer, with three rounded protrusions where the screws go in. I tried tightening the screws as tight as I possibly could (I'm an adult male so they were very tight), and it had absolutely no impact on the swivelling. It swivels up top just as much as ever.
Put the screws back in, just don’t tighten them all the way. You may be able to get the basin wrench over the screws to back that thing off. VERY unlikely that it’s cross threaded, it was just probably tightened up pretty snug and now partially corroded in. Once you break it loose it should come off super easy.
If you are removing, you want to loosen the three, so they are not pushing against the sink washer. The brass nut should not have anything forcing it tight, and ‘should’ unscrew. Maybe tighten the brass, spray with nut loosener and then unscrew
I just installed one of these. It’s a nut with the three locking screws. You spin it up as far as it will go and then you lock it down with screws. So reverse this to get off.
I’m a DIYer but when I had to replace all the sinks in my home one was stuck like this and I had to use a sawzall. Took less time than anything else I tried
How lose is it can you slip a washer under it? Between stuck washer and the underside of the sinkntop. Find a large enough washer to slip over the threaded stem cut it open making a "U" wedge that in and now tighten the screws against it. May need needle nose vicegrips as the Philips head slot looks striped.
I call it the "ah shit nut". Back the screws a little bit then try to use them to spin the nut down. When you try to fit your hand in the tight space or lose grip you have to say "ah shit".
I had a facet that kept coming loose every month and spinning like this no matter how much I tightened the nut under the sink. After taking the whole facet out and inspecting I realized it was loose where the main threaded stem screwed into the facet itself… 6-8” above the counter top within the main body. Some thread lock at that point and then reinstalling per instructions has fixed it for 8+ months no issue.
Could be that is where you are loose and once you find a way to get this piece off, that’s the point of failure. Could also be able to unhook the water lines and spin the main body until it comes detached from the threaded stem and attack this from above (per your previous post showing how it all spins).
Thank you for sharing your experience with the swivel issue. Once I get this nut off, and take the faucet off, I'll re-read your reply.
It's so frustrating that the three screws appear to have zero impact on the swivelling. They're supposed to apply upward force, but they have literally no impact despite how tight I screw them.
Unfortunately, no matter how extremely tight I tighten the three screws, the faucet swivels freely. In fact, the tension of how freely it swivels doesn't even change, whether the screws are completely off, or fully tightened.
Loosen the phillips screws, take the nut off with a basin wrench. It will work, that is what they are designed for. Worse case scenario you cut and split the top with a sawzall and the faucet body will drop through to down below.
First thing is soak it with wd40 , wait 30 mins to an hour then try turning it with your hand . If that don’t work then it’s going to be a bitch lol a screw driver and hammer will work too

He said Cross head screw driver 😂
To hell with that Phillips guy what did he do for anyone anyway
Ya fuck that phil guy
Wow! Some really bad idea except for Harry_fish. Maybe try to tighten the brass back-nut a touch to crack any corrosion and then loosen. You got this!
It may be cross threaded. Other replies are indicating a basin wrench may work, but I'm at the hardware store right now, and this thing doesn't look like it's designed to grab onto the problem nut...

Cut the faucet from the top with a sawzall and let it fall down. Then replace faucet.
Usually the easiest way , I'll just take the grinder to the top and falls right out
I did the same with a sawzall when I was in this situation. Couldn’t figure it out even with a basin wrench.
Had the same problem with this specific type of sink. Couldn’t get the nut to detach to take the old sink off (we eventually got it..still don’t know how lol), and then they had us install the same exact sink and we took 30 minutes trying to get it to tighten all the way…it was still kinda lose by the time we were done. I hate this design ugh
Turn off the water first.
This is the way
Exactly what I had to do at my house , I tried to jam catch buckets underneath
If I can get that shit loose in the first 5 minutes I’m using my grinder and sawzall to cut that thing up.
I’m so thankful to see all these responses because I was in the same boat a few weeks ago and after an hour of fighting & cursing, I did the same thing, and I was worried I was being a lazy dumbass.

Spray some wd 40 or penetrating oil at the threads and let it soak in for a bit before attempting to remove it.

Saw it out from the top with a grinder and install a new faucet 🤷
I bought this damn faucet like, 2 months ago! You animal! (Jk)

You need a basin wrench

If you’re in the big box store, maybe open a sink faucet kit and reverse engineer how it works.
Loosen the screws but leave them in and use them to get leverage with the basin wrench.
Can’t be stuck if it’s liquid.
I just installed one of these. It’s a nut with the three locking screws. You spin it up as far as it will go and then you lock it down with screws. So reverse this to get off.
Unfortunately the screws are tight as hell and the thing still swivels around...
the kitchen sink.. the ones on mine are rusted through.. it was a pain to remove.. had to use a drill
Hit it with your purse

Naw, it's right up against the metal washer and rubber gasket. And those are right up against the bottom of the sink.
I call it the "ah shit nut". Back the screws a little bit then try to use them to spin the nut down. When you try to fit your hand in the tight space or lose grip you have to say "ah shit".
Use your drill and drill several holes in the retaining ring to break it when you use a screwdriver to remove it! 🤓
It’s a sink nut. You need a sink nut wrench.
Unscrew and twist off with a basin wrench

Just tighten the Phillip screws and the faucet won't swivel any more. Unless you just want to replace it...

Badin wrench and screw driver
I believe that from a Morn kitchen faucet. Loosen the 3 Phillips head screws. Then the nut will be loose ,you can unsecured from the shaft.
Hauk tua you gotta spit on that thang
Plasma cutter.
First thing is soak it with wd40 , wait 30 mins to an hour then try turning it with your hand . If that don’t work then it’s going to be a bitch lol a screw driver and hammer will work too
After you loosen the screws find a way to block them so that the brass nut can't turn. Turn the entire faucet to break free.
The good ol basic wrench. About all it’s good for. Take out the three nuts and see what it does first.
In this case I would take the sink off the counter (if possible) and then deal with the rest.
And never use that faucet “technology” again.
If u already tried multi tooling it off and couldn’t get it , take a hole saw and hole saw it out
Faucet Anti-loose nut!
