Professional Applications & Engineering Value

This 18-8 stainless steel split lock washer delivers critical engineering solutions for vibration-prone applications across multiple industries. The standard split lock design creates continuous spring tension that counters rotational forces and prevents No. 5 screw loosening in machinery, automotive assemblies, and electrical enclosures. Manufactured from corrosion-resistant 18-8 stainless steel, this washer maintains performance in humid, chemical, or outdoor environments where carbon steel components would fail. The precise 0.133" ID and 0.236" OD dimensions ensure perfect alignment with standard No. 5 fasteners, eliminating installation issues and reducing assembly time. With Rockwell C35 hardness, the washer provides optimal balance between flexibility and strength, resisting deformation while maintaining effective locking action through thermal cycles and mechanical stress.
