DIN 6923 Flange Nut Serrated / Class 8 Steel

The serrations on the bottom of this flange nut provide a locking action, digging into the parent material when tightened down and able to withstand extreme vibrations without loosening.

Serrated flange nuts are meant to permanently mar the material they are installed against. The flanged form acts as a built-in washer to evenly distribute force over a larger area. Also known as hex nut with integrated washer.


Class 8 metric flange nuts provide a medium strength, high tensile fastening solution. Commonly paired with Class 8.8 bolts and screws.


Zinc Plated and Yellow Zinc Plated finishes provide corrosion resistance without sacrificing strength.
