DIN 6923 Flange Nut Serrated / Class 10 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. 


Hardened Class 10 metric flange nuts provide a high strength, high tensile fastening solution. Commonly paired with Class 10.9 metric bolts and screws.


Zinc Plated and Yellow Zinc Plated finishes provide corrosion resistance without sacrificing strength. Black oxide provides minimal corrosion resistance, best for dry environments.
