B6 aluminium bulkhead grubscrew

Hi
Associated B6 aluminium bulkhead grubscrews, I've lost one.
Anybody know what size they are or an associated part number?
Thanks

M3 is the thread, probably 3mm or 4mm long at a guess. Should be pretty common, you could always nick one one from an old pinion gear ;)
