Professional Applications & Engineering Value
This M2.5 spring lock washer addresses critical vibration-induced loosening in industrial assemblies through its innovative dual-sided serration design. The 18-8 stainless steel construction provides exceptional corrosion resistance for demanding environments including marine, chemical processing, and outdoor equipment. With Rockwell C38 hardness, the washer maintains spring tension while resisting deformation under cyclic loading. The top and bottom serrations create multiple biting surfaces that dig into both mating components, effectively preventing rotational slip in metric fastener systems. This engineering solution is particularly valuable in automotive subassemblies, precision instrumentation, and machinery where vibration resistance directly impacts operational safety and maintenance intervals.
Specification Summary & Compliance
This metric spring lock washer features precise dimensions (ID: 0.106", OD: 0.189", Thickness: 0.018") engineered for M2.5 screw applications. Manufactured from 18-8 stainless steel with controlled Rockwell C38 hardness for consistent performance. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. The dual serration pattern provides enhanced locking capability while maintaining standard metric washer functionality.
