Professional Applications & Engineering Value
This M42 DIN 127B split lock washer delivers critical vibration resistance in demanding industrial applications where fastener security is paramount. The zinc-plated steel construction combats corrosion while maintaining the necessary spring tension to prevent loosening under dynamic loads. Engineered to DIN 127B standards, this metric lock washer provides reliable performance in heavy machinery, construction equipment, and automotive assemblies where constant vibration would compromise standard fasteners. The Rockwell C44 hardness ensures the split lock design maintains its spring action through repeated compression cycles, making it ideal for maintenance-critical applications requiring long-term fastener integrity without frequent retightening.
