MM Bongo potentiometer nuts

[Owen]

Hi all,

 

I (as in someone is doing it for me) am in the process of putting MM Bongo electrics into a Stingray. The pots on the preamp only came with one nut. I need more. But what do I buy? I have attached pics as best I can of what I have. I am presuming that I am looking at Imperial fittings. 

 

TIA

I am guessing that my measuring doobrie is sitting inside the thread on the shaft of the pot whereas it is sitting outside the thread on the nut.

Those are 1/4" (Imperial) mini pots ?? 

Are they Alpha or CTS pots?

nuts are either 1/4"-32  OR  1/4"-28 ? Anyone know for sure?

 

The metric mini ones are M7 thread with a 9mm nut  https://www.thonk.co.uk/shop/alpha-nuts-washers/

 

Full size pots/jacks such as CTS and Switchcraft  = 3/8" x 32 thread.

Full size metric pots such as Alpha  = M8 x 0.75 thread.

Thanks Bigguy. I guess the answer is for me to buy a selection of nuts but without the info you have given me I had absolutely no idea where to start.

My brother keeps a drawer full of things waiting for the right occasion. He has told me that it is bigger than an M7 but smaller than an M8. Does that give anyone any further ideas?

 

TIA.

Ironically, my parts drawer had a couple of old pots in it which had just the right nuts. Just as well that I did not embarrass myself on a public forum before looking.
