Professional Applications & Engineering Value
This M4 wave split lock washer delivers critical vibration-dampening performance for machinery, automotive, and electrical enclosures where constant motion threatens joint integrity. The zinc-plated steel construction provides essential corrosion resistance in humid or outdoor environments, while the wave split design creates continuous spring pressure that compensates for thermal expansion and material relaxation. Engineered to DIN 128B specifications, these metric lock washers maintain precise dimensional tolerances for consistent installation torque and reliable locking performance in assembly lines. The combination of Rockwell C44 hardness and optimized thickness ensures the washer retains its spring characteristics through repeated load cycles, making it ideal for maintenance-critical applications where disassembly frequency is a concern.
Specification Summary & Compliance
This split lock washer features precise metric dimensions (4.1mm ID, 7.6mm OD, 0.7mm thickness) manufactured to DIN 128B standards for dimensional accuracy and performance consistency. The zinc-plated steel construction provides both corrosion protection and the required Rockwell C44 hardness for maintained spring tension. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and global market acceptance for industrial applications requiring verified material composition.
