Description: Star washer or most commonly referred to as an external-tooth lock washer, consists of teeth on its outside or exterior ring. This configuration is high-recommended for large fastener heads because the extra teeth provide additional clamping or holding force. When it is inserted through the head, the teeth will provide a better grip on the surface. Despite the presence of external teeth, this type of lock washer still consists of a cylindrical hole. For external-tooth washer that is affordable, you can purchase them here at MRO Supply. We supply different companies with the highest quality lock washers. Contact us to know more details.
