Overview
This external tooth lock washer is engineered to deliver superior vibration resistance and secure locking performance in heavy-duty mechanical assemblies. It is manufactured from grade 4.8 carbon steel, providing a robust balance of strength and ductility for reliable load distribution. A uniform zinc-plated finish offers a protective barrier against corrosion, extending service life in various industrial environments. The washer's design features external teeth that aggressively bite into both the bearing surface and the fastener head or nut, creating a powerful locking action that prevents rotational loosening under dynamic loads and shock. Supplied in a bulk quantity of 500 pieces, this product supports high-volume assembly operations and maintenance inventories.
