Anyone got a M4 0.5mm (metric fine) die
AdeV:
Jim & Jim - good fix between you! :)
This leads me onto a question....
I have two M4 metric dies: an 0.7 & 0.75. According to a brief google, M4x0.5 is Metric Fine, and M4x0.7 is metric coarse. So what the heck is M4*0.75?
Ned Ludd:
Hi AdeV,
Are you sure that your M4x0.75 is not in fact a M4.5x0.75?

It definitely has M4 0.75 stamped on it, but it's from a cheap-arsed set I bought the other year, so it could be misprinted...?
