I don't know the threads & pitch, but it takes a 0.5mm Allen wrench :roll eyes

The sixth item down the list is the exact part, direct from Lyman

a bit pricey for just a set screw, but it won't break the bank, and you will have the right part.

I'm new  here. But I'll see if I can help.
The screw size on the drum is metric "M4x.7"
This is on my 1997 vintage LH GPR.
I hope this helps.
