Serrated Flange Nuts – A2 Stainless Steel – M4 to M12

Serrated Flange Nuts – A2 Stainless Steel

Hexagon serrated flange lock nuts manufactured from A2 (304) stainless steel, featuring an integrated flange with serrations on the underside.

The serrated flange is designed to grip the mating surface and help resist loosening caused by vibration, while the wider bearing surface helps distribute pressure around the fixing point.

These nuts combine a hexagon nut and an integral washer-style flange in a single fixing, making them suitable for a range of engineering, machinery, automotive, fabrication and general assembly applications.

A2 stainless steel provides good corrosion resistance for many indoor and outdoor environments.
