Metric External Tooth Lock Washers DIN 6797A, Zinc

Metric tooth lock washers, also known as toothed lock washers or serrated lock washers, are a type of washer designed to prevent nuts, bolts, or screws from loosening due to vibrations or other external forces. They are characterized by their serrated or toothed edges, which create friction between the washer, the fastener, and the surface it is being fastened to. This friction helps maintain a secure and tight connection.

It's important to select the appropriate type and size of tooth lock washer for your specific fastening needs. Different tooth profiles and sizes are available, each offering varying degrees of locking effectiveness and resistance to loosening. Tooth lock washers are widely used in various industries and applications where maintaining the integrity of fastened connections is essential.
