Professional Applications & Engineering Value

This 18-8 stainless steel split lock washer addresses critical vibration-induced loosening challenges in industrial machinery, heavy equipment, and structural applications. The standard split lock washer design creates continuous spring tension that maintains clamping force despite thermal cycling and dynamic loads. The Rockwell C35 hardness provides optimal balance between flexibility and strength, preventing permanent set while resisting deformation. Engineered for 1 1/8" screw sizes, this vibration resistant washer delivers reliable performance in manufacturing, construction, and transportation sectors where fastener security is paramount. The corrosion-resistant properties of 18-8 stainless steel make it ideal for harsh environments, extending service life and reducing maintenance frequency.
