Tooth Lock Washers

Tooth lock washers, also known as serrated lock washers, are a type of washer that have serrations on one side to help prevent loosening of nuts and bolts. The serrations bite into the mating surface, creating friction and resistance to vibration and movement. This helps to keep the fastener securely in place.
Tooth lock washers are commonly used in applications where there is a risk of the nut or bolt coming loose due to vibrations or other factors. They are often used in automotive, machinery, and construction applications where security and stability are important.
