Professional Applications & Engineering Value

This M2 metric spring lock washer addresses critical vibration-induced fastener failure in precision assemblies. The dual serration technology on both top and bottom surfaces creates multiple biting points that significantly increase friction between connected components, effectively resisting rotational loosening in high-vibration environments. Manufactured from 18-8 stainless steel, it provides excellent corrosion resistance for applications exposed to moisture, chemicals, or temperature variations. The Rockwell C38 hardness ensures the spring lock washer maintains its elastic properties through countless compression cycles, delivering consistent preload in electronic enclosures, precision instruments, automotive components, and industrial machinery where reliable fastening is non-negotiable.

Specification Summary & Compliance

This precision spring lock washer features exact metric dimensions with 0.087" inner diameter, 0.157" outer diameter, and 0.014" thickness, engineered for M2 screw applications. The manufacturing process ensures consistent serration geometry and dimensional accuracy for reliable performance. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental standards for hazardous substance restrictions. Material certification confirms 18-8 stainless steel composition with Rockwell C38 hardness verification, providing documented traceability for quality-critical applications.
