Frequently Asked Questions
What hex key size do I need for this socket head cap screw?
Hex socket size depends on the screw thread size. Common sizes: #6 uses 7/64", #8 uses 9/64", #10 uses 5/32", 1/4" uses 3/16", 5/16" uses 1/4", 3/8" uses 5/16". For metric: M3 uses 2.5mm, M5 uses 4mm, M6 uses 5mm, M8 uses 6mm, M10 uses 8mm.
Does Black Oxide finish provide corrosion protection?
Black Oxide provides mild corrosion resistance through a controlled oxidation process. It is dimensionally stable (no plating buildup), will not chip or flake, and is suitable for indoor use. For outdoor or wet environments, additional oil coating or a different finish (zinc, stainless) is recommended.
