Professional Applications & Engineering Value

This 410 Stainless Steel tooth lock washer delivers critical vibration-resistant fastening for industrial equipment, automotive assemblies, and machinery subjected to constant dynamic stresses. The unique internal/external tooth configuration creates multiple biting points that mechanically lock against both the screw head and base material, effectively solving common loosening issues in high-vibration environments. Manufactured to ASME B18.21.1 standards, these inch system washers provide reliable performance for No. 10 screw applications where precise dimensional control and consistent spring action are essential. The corrosion-resistant properties of 410 stainless steel ensure long-term functionality in exposed or harsh operating conditions, making these tooth lock washers ideal for maintenance-critical applications across multiple industries.
