Stuck nylon nut

I need help. I’m trying to replace a coin acceptor but I can get this nut off. It’s just spinning around the nylon insert. I’ve tried to put upward pressure on it, I’ve tried heating it. I don’t know what else to do. The stud on the other side is already broke off or I would just break this on.

Is the whole stud spinning with the nut? What tool are you using to try to remove - some of my nut drivers wouldn't grab that nut with the stud that long?
 
The stud isn't spinning, just the nut. I started out with a socket which is what I've always used. After that I tried some needle nose pliers so I could grab it and pull up on it with some upward force while spinning and that didn't work. I also tried wedging a small screwdriver underneath it and then spinning it and that didn't work either.
 
Maybe try a nut splitter tool if you can get it in there. If the nut is spinning and not loosening and the stud isn't spinning, sounds like your threads maybe messed up
 
It looks like a lock nut with a nylon insert. Since you've only got one stud left on the top of the coin acceptor you want to be very careful that you don't break off this stud. I'd use a Dremel tool and careful cut off the nut on one side then turn the 180 deg and then cut off the other side. Whatever you do you want to be careful to not damage the stud.
 
Ya , but it's expensive i seen try Valley with specialty equipment spot weld them studs. Who has the tool . That would restore it.

Well did get your problem lock nut off of the stud?
 
What about if you took a chisel to the nut from the top? You could slide a piece of poly tubing over the stud so you didn't damage it with the chisel. A few good taps and I bet you could pry the nut apart with a screwdriver and get it right off.

I like Vern's idea of just melting the plastic as you pull it away. If that doesn't work out (broken stud) I've just drilled a hole through the face plate with a countersink and put a small stainless flat head in (see attached).
A decal, if needed, will go right over it.

Heating it up and melting the nylon/plastic insert won't work. It's a steel locking nut with a nylon/plastic insert.
