Professional Applications & Engineering Value
This M18 spring lock washer is engineered to address common industrial challenges like loosening due to vibrations and dynamic loads. Made from zinc-plated steel, it offers excellent corrosion resistance, ideal for outdoor machinery, automotive assemblies, and heavy equipment. The dual-sided serrations on top and bottom bite into mating surfaces, providing a locking action that prevents back-off and maintains clamp force. With a Rockwell C38 hardness, it withstands repeated stress without deformation, ensuring reliable performance in metric fastening systems. Its compliance with RoHS and REACH makes it suitable for electronics, aerospace, and other sectors requiring eco-friendly components, reducing downtime and maintenance costs.
Specification Summary & Compliance
This washer features precise dimensions with an ID of 0.748", OD of 1.063", thickness of 0.055", and overall height of 0.091", designed for M18 screw sizes in the metric system. It adheres to standard manufacturing practices for spring lock washers and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no hazardous substances are present. The Rockwell C38 hardness confirms consistent quality and performance in industrial applications.
