External tooth lock washers have teeth around the outer diameter that bite into the fastened material and the bolt head to prevent it from loosening. They are ideal for large screw and bolt heads. Their teeth also act as a shock absorber to withstand shocks and vibrations. External tooth lock washers are commonly made from stainless steel for corrosion prevention and are available in various diameter sizes.
