FAQ
How do serrated flange bolts lock?
The serrations dig into the mating surface when tightened and resist turning backward. They mark the surface, so don't use them on finishes you need to protect or on hardened surfaces.
Do flange bolts need a washer?
No. The built-in flange spreads the load like a washer, so one part does the job of two and speeds up assembly.
