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.
Why does a carriage bolt have a square neck?
The square neck beneath the round head wedges into the wood as the nut is tightened, preventing the bolt from rotating. This allows tightening from one side only — perfect for deck and fence construction where you can not access the back side of the bolt.
