Serrated Flange Nuts are a one-piece, all metal, free-spinning lock nut. Cold formed teeth on the base of the nut eliminate the need for lock washers. The flange base distributes the load over a larger area and is ideal for oversized holes. It withstands severe vibration and shock loads. Serrated Flange Nuts are reusable without loss of locking power. Torque required to loosen the nut is approximately 25% lss than the application torque.
