Professional Applications & Engineering Value
This spring lock washer delivers critical vibration-dampening performance for industrial applications where mechanical stability is paramount. The 18-8 stainless steel composition provides excellent corrosion resistance in marine, chemical processing, and outdoor environments, while the dual serration technology (top and bottom) creates multiple biting surfaces that significantly enhance anti-loosening capabilities. Engineered with Rockwell C38 hardness, this washer maintains structural integrity under repeated stress cycles, making it ideal for heavy machinery, automotive assemblies, and electrical enclosures where thermal cycling and vibration are constant challenges. The inch/metric compatibility (3/8" and M10) ensures seamless integration across international equipment standards.
Specification Summary & Compliance
This spring lock washer features precise dimensions: 0.413" inner diameter, 0.63" outer diameter, and 0.063" overall height with 0.039" thickness. Manufactured from 18-8 stainless steel with Rockwell C38 hardness rating, it's designed for use with 3/8" and M10 fasteners. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while meeting international environmental standards.
