Frequently Asked Questions
What is the difference between Grade 5 and Grade 8?
Grade 5 (medium carbon steel, 120 ksi tensile strength) is suitable for most industrial applications. Grade 8 (alloy steel, 150 ksi tensile strength) is used for high-strength applications like automotive suspension and machinery. Grade 5 hex heads have 3 radial lines; Grade 8 has 6 radial lines.
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.
