Detail & Specs
M8X1.25 Serrated Hex Head Flange Bolt - A4 Stainless DIN 6921
The serrations on the bottom of the flange provide a locking action, digging into the parent material when tightened down. Serrated flange bolts are meant to permanently mar the material they are installed against.
Flange bolts can be used with many different styles of locking and non-locking nuts to clamp tightly to whatever the bolt is being used to secure. A wrench is used to install and tighten hex flanged bolts.
