Overview
This internal tooth lock washer is engineered to provide a reliable, vibration-resistant locking solution for critical bolted assemblies. Manufactured from high-grade Stainless Steel 304, it offers excellent corrosion resistance for demanding industrial environments. The design features precision-cut internal teeth that bite into the bearing surface of the nut and the underside of the bolt head, creating a powerful mechanical lock that prevents rotation and loosening. Supplied in a bulk package of 1000 units, it is ideal for high-volume production, maintenance, and repair operations where fastener security is paramount.
