Overview
This 304 Stainless Steel Internal Tooth Lock Washer is engineered to provide a reliable, vibration-resistant locking solution for shafts, studs, and other cylindrical fasteners. Designed with precision-formed internal teeth, it creates a powerful bite into the mating surface to prevent rotational loosening and back-out under dynamic loads, shock, and vibration. The use of corrosion-resistant 304 stainless steel ensures durability and long-term performance in harsh or washdown environments, while the plain finish offers a clean, professional look suitable for a wide range of assemblies. Each package contains 100 washers, providing cost-effective inventory for production lines or maintenance kits.
