[sdiy] Poteniometer nuts?

[Speth, John]

Hi group-

I'm in need of some potentiometer nuts and I don't know what size they are.  I need help finding out which kind to buy.

I have a bunch of pots I got surplus but they don't have any nuts.  When I search the web for sources, I need to provide the sizes and thread pitch to query availability.  There are no markings on the pots so I can't cross reference these.  I have an example nut that fits too.

I tried using a tap and die set to hunt for the right match but nothing matched.  It must be a non-typical nut.

Can anyone help me out of this problem?  Where can I get nuts with some certainty that I'm getting the right ones?  Aren't these nuts somewhat standard for pots?

The pots are nothing special.  They look identical this: http://www.geofex.com/Article_Folders/potsecrets/pot1.JPG.  Mine are the small version of that (about 5/8" body diameter and a 5/16" diameter shaft).

Thanks...
