Overview
This internal tooth lock washer is engineered to provide a secure, vibration-resistant locking solution for fasteners on shafts, studs, and similar components. It is designed to prevent nuts and other fastened parts from loosening due to dynamic loads, shock, or vibration in assembled machinery and equipment. Manufactured from grade 4.8 carbon steel, it offers dependable mechanical strength for a wide range of general industrial applications. The zinc-plated finish provides a protective layer against corrosion in typical operational environments, ensuring longevity and consistent performance.
Key Features
Internal tooth design bites into both the bearing surface and the fastener for superior locking action Grade 4.8 carbon steel construction provides reliable tensile strength and durability Zinc-plated finish offers effective corrosion resistance for use in standard conditions Prevents loosening from vibration, thermal cycling, and dynamic stress Consistent tooth profile ensures uniform grip and load distribution Supplied in a bulk package for inventory management and job site efficiency
