The amp I am building has a wood front and my pots threads are flush so I am unable to put a standard nut on it. What type of nut is in the picture and where can I get one? On eBay it says the pots thread width is 7mm. At the moment the pot is secured with a wood screw and although it’s not going anywhere it is not ideal.

I would counterbore on the front about half the material thickness,
and then use a washer and nut to fasten the pot.

Behringer uses these on their PA speakers for fixing the amp cage to the back plate.
Think as amp case feet or standoff. The screw then goes from the outside of the speaker.
These are rivetted to the amp case.
The problem is, if You have the habit of fixing the screws from time to time, they get off or break and You have to disassemble the whole amp cage to replace them with ordinary screws. The nut then goes from the outside, so backwards oriented.

After a long search I could not find any M7 Tee Nuts. They seem to skip M7, I only found one and it was pronged. A Tee Nut would have been the best solution.
I will have to work out a way to do a counterbore without a counterborer.
Thanks for all your answers and help.

Have you tried doing a search for threaded insert, they are not the same but may suit your application.

mcmaster has whole categories of tee nuts, rivit nuts, and weld nuts. The tee nuts nail to the back of your wood the way a 1935 Ford body was assembled. T nuts come in M6 and M8, including low prong varieties for hardwoods that would split. McMaster-Carr
I've never seen a 7 mm cap screw.

I did the counterbore. It came out really neat somehow and then I put the volume knob over it so nobody will ever see it. I’m sure I would have found one if I had kept looking, if it had been an M6 or M8 I would have had a big lots to choose from. I did find one M7 Tee Nut but it had tongs and they wanted £4 delivery.
