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 is the difference between partial thread and full thread?
Partial thread (also called shoulder bolt or tap bolt) has an unthreaded shank for shear strength. Full thread (fully threaded cap screw) provides more clamping engagement. Standard cap screws above 6 inches long are typically partial thread.
