Zinc Lock Washers- Internal Tooth
Serrated Lock Washers in Zinc Plated Steel
Internal Tooth Lock Washers, also known as serrated washers, lock washers that create tension between the washer's teeth and the installation surface. This tension makes the fastener assembly resistant to rotation. Internal Tooth Lock Washers are used to lock assemblies underneath the head of the fastener, and are often chosen over External Tooth Lock Washers for aesthetic reasons.
Internal Tooth Lock Washers in this selection are made of Zinc Plated Steel.
