Professional Applications & Engineering Value
These M4 split lock washers solve critical vibration-induced loosening problems in machinery, automotive, and electrical assemblies. The zinc-plated steel material provides essential corrosion resistance while maintaining the Rockwell C44 hardness needed for repeated compression cycles. The curved split design creates continuous spring pressure that compensates for thermal expansion and vibration, making these DIN 128A compliant washers ideal for motors, pumps, and precision equipment where fastener security is paramount. Their metric dimensions ensure compatibility with standard M4 fasteners in European and international manufacturing applications.
Specification Summary & Compliance
Precision manufactured to DIN 128A standards with exacting dimensional tolerances (4.1mm ID, 7.6mm OD, 0.7mm thickness). The curved split lock washer type provides consistent spring performance with Rockwell C44 hardness certification. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors while maintaining superior mechanical properties.
