Overview
This internal tooth lock washer is engineered to provide a dependable, vibration-resistant locking solution for fasteners and shafts in demanding industrial environments. Manufactured from grade 4.8 carbon steel, it delivers a robust balance of strength and flexibility. A uniform zinc-plated finish offers a protective layer against corrosion, extending the component's service life in various operating conditions. The design utilizes internal serrations that bite securely into the mating surface of a bolt head or nut, as well as the bearing surface, to prevent rotational loosening caused by dynamic loads, shock, and vibration. Supplied in a bulk package of 1000 units, this washer is ideal for high-volume assembly lines, maintenance operations, and MRO inventories where consistent, reusable locking performance is critical.
