Toothed Lock Washers feature internal or external teeth that bite into the fastener material and the mating surface, preventing rotation and maintaining tension. This design provides a reliable locking mechanism, especially in applications prone to loosening due to vibration. Toothed Lock Washers are commonly used in electronics, automotive, and machinery industries where secure fastening is critical. They are ideal for securing electrical connections, automotive assemblies, and machinery parts that experience continuous motion and vibration. Their ability to prevent loosening and maintain tension makes them essential in ensuring the reliability and safety of various applications.
