Professional Applications & Engineering Value

This spring lock washer delivers critical engineering solutions for vibration-prone assemblies where fastener integrity is paramount. The top serration location creates maximum bite force against mating surfaces, effectively countering rotational loosening in machinery, automotive, and electrical enclosures. Manufactured from high-grade steel and heat-treated to Rockwell C40 hardness, it maintains spring tension through thermal cycling and mechanical stress. The precise 0.142" ID and 0.362" OD dimensions ensure perfect alignment with No. 6 screws, eliminating installation issues while the controlled thickness range provides consistent clamping force. Ideal for maintenance-critical applications where vibration resistance directly impacts operational safety and equipment longevity.
