Supplier for Banjo missing nuts n bolts

[Jacob]

Old banjo from ebay. Bolts missing from "Prusch Kirshner" tailpiece. Can't get spares, wondering where I could buy suitable alternative small bolts. It's two bolts and one thumbscrew in the back plate which you can just see in this pic. 3 bolts would do, or screw headed.

Thanks for that!
Probably be OK though there seem to plenty of off the peg sources and it's not high tech or spec

Those screws look like they are about 6/32 thread some fender stratocaster pickup height screws might fit. You should easily find them at a guitar repairer.

Průcha are in the Czech Republic (https://www.pruchabanjos.cz/contact/). Their European origin might point away from imperial hardware.

Well If they are metric then you should have no trouble finding equivalents in the UK. You would probably find that they(Prucha) would send you the replacement parts. The only problem being the post brexit fines by the customs and uk postal services.

Once you know the size try D Middleton stainless. They do high quality bolts with smooth heads as in the picture.

I measure it (from a good fitting thread) as 3.8mm diameter and 15 crest per mm (crest to crest). What size bolt setscrews should I ask for?
Is that simply M4 ?

15 crest per centimetre (10mm) perhaps.

M4 is 0.7mm pitch. Set the caliper to 14mm exactly and you should count 20 complete pitches for M4.

There is a balance between a greater number of pitches giving greater accuracy and the risk of losing count as you go.

The screws that hold kitchen and Ikea drawer and door handles on are M4.

I've probably got some in a box.
Thanks for that.

They haven't got the screws but I've a new head on the way from them.
It's an Ozark 2141gn which is a good quality machine except this one has been worked over rather badly. But the Kirshner tail is a luxury add on, along with 5 fifth string rail spikes. They've made such a bad job of the rest of it they probably gave up altogether and it looks completely unplayed, just badly set up.
Got some temporary screws together and have ordered some nice shiny SS ones.
