Overview
This external tooth lock washer is engineered to provide a reliable, vibration-resistant locking solution for fasteners on shafts and studs. Manufactured from corrosion-resistant 304 stainless steel, it is designed for use in demanding industrial, automotive, and marine applications where fastener security is critical. The external teeth are precision-formed to bite into both the bearing surface of the nut and the workpiece, creating a positive mechanical lock that resists rotational loosening under dynamic loads and vibration.
