Overview
This external tooth lock washer is engineered to provide a reliable and permanent locking solution for bolted assemblies. It is designed to prevent fastener loosening caused by vibration, dynamic loads, and thermal cycling. Manufactured from durable 304 stainless steel, this washer offers excellent corrosion resistance for use in demanding environments. The external tooth configuration ensures maximum bite into both the workpiece and the fastener head or nut, creating a secure mechanical lock that maintains clamp load integrity. Supplied in a bulk package of 500 units, it is an efficient choice for high-volume manufacturing, maintenance, and repair operations.
