Professional Applications & Engineering Value

This M3 split lock washer delivers critical vibration-resistant fastening solutions for industrial machinery, automotive assemblies, and electronic enclosures where loosening under dynamic loads poses significant reliability risks. The curved split design creates continuous spring tension that compensates for thermal expansion, material relaxation, and operational vibrations. Manufactured from zinc-plated steel with Rockwell C44 hardness, these metric lock washers maintain their spring properties through repeated loading cycles while providing corrosion resistance. The precise 3.1mm ID and 6.2mm OD dimensions ensure perfect alignment with M3 fasteners, preventing installation issues and delivering consistent clamping force in high-vibration environments where fastener security is paramount.

Specification Summary & Compliance

This split lock washer features precise metric dimensions (3.1mm ID × 6.2mm OD × 0.6mm thickness) engineered for M3 screw applications. Manufactured to DIN 128A standards with curved split configuration and Rockwell C44 hardness for consistent spring performance. The washer demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and unrestricted use across industrial sectors requiring certified components.
