Professional Applications & Engineering Value
This M4 spring lock washer delivers exceptional engineering value through its specialized curved spring design and zinc-plated steel material. The carefully engineered curvature generates continuous axial force that actively counters vibration-induced loosening, making it ideal for machinery, automotive assemblies, and electrical enclosures where vibration resistance is critical. The Rockwell C42 hardness ensures the washer maintains its spring properties through repeated compression cycles, while the zinc plating provides reliable corrosion protection in demanding industrial environments. As a DIN 137A compliant component, it offers guaranteed dimensional precision for seamless integration with M4 fasteners in metric-based assembly systems.
Specification Summary & Compliance
This spring lock washer features precise dimensions of 4.3mm ID and 8mm OD with 0.5mm thickness and 1.6mm overall height, manufactured to DIN 137A standards for dimensional accuracy. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while meeting the rigorous demands of industrial fastener applications. The zinc-plated steel construction combined with Rockwell C42 hardness provides optimal performance characteristics for vibration-prone assemblies.
