Overview
This external tooth lock washer is a precision-engineered fastener component designed to prevent the loosening of bolted joints in demanding industrial and mechanical applications. Manufactured from grade 4.8 carbon steel, it provides a dependable balance of strength and flexibility. The washer's primary function is to maintain clamp load by having its external teeth bite firmly into the nut or bolt head and the underlying surface, creating a strong resistance to rotational forces caused by vibration, dynamic loads, and thermal cycling. The zinc-plated finish offers a protective layer against corrosion, enhancing durability in various operational environments. Sold in a convenient package of 100 units, it is an essential inventory item for maintenance, repair, and assembly operations.
