Overview
This 304 Stainless Steel Internal Tooth Lock Washer is engineered to create a secure, vibration-resistant joint in mechanical assemblies. It is specifically designed for applications where reliable locking performance is critical, yet the connection must be serviceable for future maintenance or adjustment. The washer's internal teeth are precision-formed to bite into both the mating surface of the workpiece and the underside of the nut or bolt head, generating significant resistance to rotational loosening caused by shock, vibration, and dynamic loads. Manufactured from austenitic 304 stainless steel, it offers excellent corrosion resistance for use in harsh, wet, or chemically aggressive environments.
Key Features
Superior locking action from multiple internal teeth that dig into mating surfaces. Constructed from corrosion-resistant 304 stainless steel for durability. Plain, non-plated finish suitable for a wide range of industrial applications. Ideal for assemblies that require periodic disassembly and reassembly. Provides a reusable locking solution compared to chemical threadlockers. Cost-effective, bulk packaging for production lines or maintenance inventories.
