Fastener Locknut Flanged 1/4-20

Fastener Locknut Flanged 1/4-20

This is a 1/4-20 serrated flange locknut, a one-piece, self-locking fastener designed to resist loosening caused by vibration. The integrated serrated flange acts as a built-in washer, distributing the load over a wider area and biting into the mating surface to prevent the nut from backing out. This eliminates the need for a separate lock washer, simplifying assembly. It is a common hardware component used for securing non-critical parts like brackets, panels, and guards on concrete mixers and other heavy equipment.

• Integrated flange acts as a washer to distribute pressure.
