Professional Applications & Engineering Value

This spring lock washer delivers critical engineering solutions for industrial equipment subject to vibration and thermal cycling. The conical shape with external teeth creates multiple biting points that resist rotational forces, preventing fastener loosening in machinery, automotive assemblies, and heavy equipment. Manufactured from high-grade steel, it maintains spring properties under repeated loading cycles while the specific 1.583" ID ensures perfect alignment with standard 1.563"-18 fasteners. The chamfered bearing nut compatibility makes it ideal for precision bearing applications where secure positioning is paramount. By combining the spring locking action with tooth engagement, this washer addresses the dual challenges of vibration-induced failure and assembly creep in demanding industrial environments.

Specification Summary & Compliance
