Professional Applications & Engineering Value

This zinc-plated steel spring lock washer delivers critical vibration damping in demanding industrial environments where fastener security is paramount. The top serration design bites into mating surfaces, creating exceptional resistance to rotational forces that cause conventional fasteners to loosen. Engineered specifically for No. 6 screw applications, this washer maintains consistent spring tension through thermal cycling and mechanical stress. The zinc plating provides reliable corrosion protection in manufacturing, automotive assembly, and electrical equipment applications where environmental factors threaten fastener integrity. With its precision inch system dimensions and Rockwell C40 hardness, this component ensures long-term reliability in machinery, enclosures, and structural assemblies subject to constant vibration and dynamic loads.

Specification Summary & Compliance

This spring lock washer features precise dimensional specifications including 0.142" inner diameter, 0.362" outer diameter, and 0.025-0.031" thickness range. Manufactured to standard inch system tolerances with top-located serrations for optimal performance. The component meets Rockwell C40 hardness standards and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial applications.
