Professional Applications & Engineering Value

Engineered for demanding industrial applications where vibration-induced loosening compromises assembly integrity, these M3 spring lock washers deliver exceptional reliability. The curved spring design creates continuous axial pressure that counters rotational forces, while the zinc-plated steel material provides essential corrosion resistance in manufacturing environments. With Rockwell C42 hardness, these DIN 137A compliant washers maintain their spring characteristics through repeated compression cycles, making them ideal for machinery, automotive assemblies, and electrical enclosures where vibration resistance is critical. The precise 3.2mm ID ensures perfect alignment with M3 fasteners, preventing misalignment and distributing clamp load effectively.

Specification Summary & Compliance
