M4 Serrated Flange Nut

Flange serrated nuts are a type of nut that features a built-in flange or collar for added stability and strength when attaching two components. The collar is designed to provide extra surface area for bolts, screws, or other fasteners—allowing them to be tightened down more securely. This makes them ideal for applications where vibration or movement may occur, making them especially popular in industrial settings.

The unique design of flange serrated nuts helps increase the contact surface area between the nut and bolt—providing a stronger grip than standard nuts. Additionally, the locknut’s shape helps keep it from backing off due to vibrations or movement and provides additional support against turning forces exerted by other components attached to the same bolt.
