Professional Applications & Engineering Value

This M3.5 split lock washer addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and electrical equipment. The curved split lock washer design generates continuous spring pressure that compensates for settlement and wear, maintaining clamp load where conventional flat washers fail. Manufactured from zinc yellow-chromate plated steel, this fastener provides essential corrosion resistance for applications exposed to moisture, chemicals, or outdoor elements. The Rockwell C44 hardness ensures the washer retains its spring properties through thermal cycling and dynamic loads, making it ideal for vibration resistant applications in motors, pumps, and precision equipment where reliable fastening is non-negotiable.

Specification Summary & Compliance

This metric split lock washer features precise dimensions of 3.6mm ID × 6.7mm OD × 0.6mm thickness, specifically engineered for screw size M3.5. Manufactured in compliance with DIN 128A standards, ensuring consistent dimensional accuracy and performance characteristics. The zinc yellow-chromate plating provides corrosion protection while meeting industry requirements for environmental compliance. The curved split design and Rockwell C44 hardness maintain the washer's locking capability throughout its service life, delivering reliable performance in demanding mechanical applications.
