Professional Applications & Engineering Value

This spring lock washer delivers critical engineering solutions for applications where vibration-induced loosening compromises safety and performance. The 18-8 stainless steel construction provides inherent corrosion resistance, making it ideal for chemical processing, marine, and outdoor industrial equipment. The dual serration pattern on both top and bottom surfaces creates multiple biting edges that significantly improve grip on mating surfaces, preventing rotation and maintaining clamp load in high-vibration environments. With Rockwell C38 hardness, this washer maintains its spring properties and serration effectiveness through repeated loading cycles. The versatile design accommodates both 1 3/8" and M36 screw sizes, offering flexibility for equipment manufacturers working with mixed measurement systems in heavy machinery, structural assemblies, and transportation applications where reliable fastening is non-negotiable.
