Hi all...

I don't own a lathe and I am in need of a few inches of threaded rod in M6x.5 for a new front sight post for an SPR22.

I thought I would be able to just go to Fastenal, Grainger, etc and buy some capscrews with this thread, but I am finding out this is a very unusual pitch in the M6 diameter (std appears to be x1 and fine is x.75)

Can anyone recommend a source?
