Overview
This external tooth lock washer is engineered to prevent fastener loosening caused by vibration, shock, and dynamic loads in mechanical assemblies. Manufactured from high-quality 304 stainless steel, it offers excellent corrosion resistance for use in demanding environments, including those exposed to moisture and chemicals. The washer's external teeth are designed to bite firmly into both the bearing surface and the fastener head or nut, creating a powerful locking action that resists rotational movement. Its A2-70 strength class ensures reliable mechanical performance and durability. Packaged in quantities of 5,000, this washer is an ideal solution for high-volume manufacturing, maintenance, and repair operations.
