Ext-Star Washer

Ext-Star Washers, also known as External Star Lock Washers, feature outward-projecting serrated teeth that bite into the fastener and mating surface. This design increases friction, prevents rotation, and ensures the fastener remains tight even under vibration or shifting loads. Widely used across mechanical, electrical, and industrial assemblies, Ext-Star Washers provide reliable, high-performance locking in demanding environments.
