Screws used in ARP synths.

Ok, I often have a hard time judging imperial thread sizes for screws.. Metric - no problem.

I need a few small screws (around 4mm thread size) for a few ARP synths.. But F me if I know what size they are... Or what the pitch is.

Can some US tech please tell me what screw size is used in most ARP gear.. (the screws that hold the PCB's in place on the ARP Oddy / Quadra etc)

Thanks in advance.

(if this belongs in the geek forum, please move)

I'm not sure of the exact size but #4, #6, #8 are probably what your after.

A #8 is fairly close to a converted 4mm.

But a small assortment kit and you should be set. Let me know if you need help getting a kit.

Excuse my ignorance but doesn't #4 #6 etc apply to wood screws and not machine screws?

Pity most local hardware stores only have metric and a few odd imperial sizes.

The terms "#4, #6" etc. refer to both wood screws and machine screws. When referring to machine screws, there is typically an additional bit of info along with it to identify the number of threads per inch. Typical machine screws are:

#4-40 (#4 diameter with 40 threads per inch)

#6-32 (#6 diameter with 32 threads per inch)

etc.

Ahh. I always saw 8-32 and thought the screw size was 8/32 of an inch.. Now I see for #8 there are two pitches.. 32 & 40.. Makes a bit more sense.

As an initial guess, I'd imagine 32 would be more standard?

I'll pick a few 8-32 off eBay and see if they fit

Yup. The most common sizes are #4-40, #6-32, #8-32 and #10-24.
