Frequently Asked Questions
What pilot hole size do I need for this self-tapping screw?
The pilot hole should be approximately 70-80% of the screw outside diameter. For #6 screws use .128" drill (#30). For #8 use .157" (#21). For #10 use .180" (#15). For 1/4" use .228" (#1). Always test in scrap material first to verify proper engagement.
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.
