DIN 6331 Class 10 Steel / Extended Height Tall Collar Flange Nut

Extra tall non-locking flange collar nuts provide additional thread engagement. Non-locking flange nuts have a smooth bottom flange that acts as a built-in washer to evenly distribute force over a larger area against the fastening surface.

Non-serrated flange nuts will not damage the threads of bolts or screws and can be reused. They are popular for applications that require frequent removal and re-installation. Also known as a high metric flange nut.


DIN 6331 Collar Type Nut without serrations / smooth *The overall height for this type of flange nut is always 1.5x the diameter*
