Frequently Asked Questions

What hex key size do I need for this socket head cap screw?
For this #3-56 Socket Head Cap Screw, use a 5/64" hex key (Allen wrench).
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.
