Overview
This external tooth lock washer is engineered to provide superior vibration resistance and locking security in critical fastening assemblies. Designed for B2B and industrial applications, it prevents nuts, bolts, and screws from loosening under dynamic loads, shock, and vibration. The washer's external teeth are precision-formed to bite into both the fastener head and the bearing surface, creating a firm, non-slip grip that maintains clamp load and joint integrity over time.
