Internal Tooth Lock Washers

Usages for Internal Tooth Lock Washers

An internal tooth lock washer is a circular metal washer with serrated teeth pointing inward from the inner circumference. These teeth dig into the nut or bolt head as well as the connected material, creating friction that helps lock the fastener in place. This design improves the washer’s ability to resist loosening from vibration and torque, making it ideal for applications where parts are subjected to high rotational forces or continuous motion.
