Overview
The 304 Stainless Steel Internal Tooth Lock Washer is engineered to provide a permanent, vibration-resistant locking action in critical bolted assemblies. Its design utilizes a ring of precision-formed internal teeth that aggressively bite into the underside of the nut and the surface of the workpiece. This creates a prevailing torque that resists rotational loosening caused by shock, vibration, and dynamic loads. Manufactured from corrosion-resistant A2-70 grade stainless steel, this washer is ideal for applications where reliability and long-term fastener security are paramount. The bulk package of 500 pieces supports high-volume production and maintenance operations.
Key Features
Internal tooth design for superior vibration resistance Teeth bite into both nut and workpiece to prevent rotation Corrosion-resistant 304 stainless steel construction A2-70 material grade for high tensile strength Plain, unfinished surface for universal compatibility Bulk packaging for cost-effective inventory management
