Frequently Asked Questions
What does the metric class number mean?
The first number indicates tensile strength (e.g., 12 = 1,200 MPa). The second number is the yield-to-tensile ratio. So Class 12.9 has 1,220 MPa tensile strength and yield at 90% of tensile. Class 12.9 is equivalent to inch Grade 8.
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.
