FAQ
What hex key fits an M8 socket head cap screw?
A 6mm hex key (Allen wrench).
How are metric screws measured?
Diameter x pitch x length, in millimeters. Length is measured from under the head to the end of the screw, except flat (countersunk) heads, which are measured overall.
Does black oxide prevent rust?
Only lightly. Black oxide with an oil film is for indoor, dry use. For wet or outdoor use, choose stainless steel socket screws.
