Serrated Flange Locknuts

Metric and standard serrated flange locknuts are specialized locknuts that are constructed entirely of high strength metals. Serrated flange nuts are ideal for high vibration environments due to deformed threading that allows the nut to lock in place for a strong, reliable hold. These nuts offer a wide flange or collar at the base to increase available surface area for an even load distribution. By dispensing the load, flange locknuts improve the integrity and strength of the connection while locking in place at the same time. The underside of the flange is serrated or has teeth to grip into the mating base. Be aware that soft base material can be damaged by the serrated underside; however, this feature also increases the holding power.
