iso/din naming of a screw
thank you for giving me indication to be understood by german/american engineer when i need to register a new screw as standard part:
example:
cblx40-m8x1.25-lg60, chamfer point. for french engineer this means standard head cylindrical spheric top large base 6 lobes print size40.
i am asked to accept each single radius cold forgeing needs!
