Help! I NEED an imperial-sized locknut/panel nut.

[UlricvonCatalyst]

I've been trying to get my Jazzmaster together for a looooooong time and opted for a complete rewire as I was replacing the pickups, scratchplate, etc. anyway.

Got an acquaintance in the USA to buy in a bunch of CTS pots, etc. and forward them onto me so as to avoid delays/customs fees.

Somehow I ended up with a duff locknut on one of the CTS mini-pots in the rhythm section (the pots that have the roller knobs attached to them).

Okay, I've found out that they are 1/4"-32 size but I can't for the life of me find a UK supplier of less than 100 of the fuckers.

I would be happy to buy another mini-pot just to get the nut, but it's impossible to tell if it'll be the right size as few suppliers include that depth of information.

I'd rather avoid spending upwards of a tenner if I can help it or being landed with 99 spares just to get a single nut, but my rebuild is totally stalled until I can find one.

Can anyone help with some sage advice, pointers, whatever...?
