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.
What hex key size do I need for this socket head cap screw?
Hex socket size depends on the screw thread size. Common sizes: #6 uses 7/64", #8 uses 9/64", #10 uses 5/32", 1/4" uses 3/16", 5/16" uses 1/4", 3/8" uses 5/16". For metric: M3 uses 2.5mm, M5 uses 4mm, M6 uses 5mm, M8 uses 6mm, M10 uses 8mm.
