Professional Applications & Engineering Value
These M2 metric split lock washers deliver critical vibration-dampening performance for precision assemblies where micro-movements can cause catastrophic failure. The zinc-plated steel construction provides sacrificial corrosion protection while maintaining the spring hardness (Rockwell C44) necessary for sustained locking pressure. Engineered to DIN 127B standards, these washers solve common industrial challenges in electronics manufacturing, automotive subsystems, and precision instrumentation by preventing thread back-off without requiring additional locking compounds. The split design creates continuous tension that compensates for thermal expansion and vibration-induced relaxation, making them ideal for M2 screw applications in confined spaces where reliability is paramount.
Specification Summary & Compliance
This standard split lock washer features precise dimensions (2.4mm ID × 4.4mm OD × 0.4-0.6mm thickness) manufactured to DIN 127B specifications. The product maintains dimensional accuracy per metric system requirements and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, including the latest SVHC updates. The Rockwell C44 hardness ensures consistent performance across industrial temperature ranges and loading conditions.
