Flange Nut Tall / Extended Height Collar - A4 Stainless DIN 6331
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.
