Ok so I found myself with out enough hardware. I have a 100K dual audio taper pot from Radio Shack and I lost the nut. It is one for mounting in a 5/16 hole so I assume it is a 5/16 treaded sleeve with a 1/4 inch shaft but I can't find any hardware for it.
Now I could just go buy another pot with hardware but after looking I find that I have other pots with no hardware and some of them are the same sleeve. I have hardware for the bigger pots. I guess you might say the standards. Searching Google comes up with no hardware except for at Electronic Goldmine, where I bough a bunch that are to large. Who makes this stuff, some far east company, and they secretly ship them to Switchcraft and other manufactures of potentiometers. John, WA5BXO
