Frequently Asked Questions
How thick of metal can this self-drilling screw drill through?
Self-drilling screws are rated by drill point number: #2 point drills 0.018"–0.140" (24–9 ga), #3 point drills 0.060"–0.210" (16–3 ga), #4 point drills 0.110"–0.500", #5 point drills 0.250"–0.625". Match the point to your material thickness for proper drilling performance.
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.
