There is no reason such critters should exist.

1/4"-40????? No! 1/4" 20! UNF. 1/4" 16 UNC. 4-40 UNC, 4-56 UNF. All standard. Syntax error. Parsing error. Reality check error.

No, those are usually 3/8-32 and are also use the same thread as threaded military BNC panel mount connectors. Also used in some incandescent lamp mounting hardware, although that seems to be moving to 1/8" pipe.

Those are machine screw nuts; that's not what OP is looking for.

Hve you ever seen a control panel nut? An Alcoswitch? A phone jack?

These are large ID (relatively), thin, fine-thread nuts.

I misread it at first and found some 15/32-32s, but then realized that 15/32 is almost 2X 1/4, duh.

But Alcoswitch definitely springs to mind, and mini pots and rotary switches and stuff.

Cheers! Rich

It has been a while since i installed potentiometers or 1/4" "phone" jacks. memory fades. If i had seen 9/16-40 i might have remembered sooner. "panel control nuts" seems to give the best resuts in Google.
