Professional Applications & Engineering Value

This M4 wave split lock washer delivers critical vibration-resistant performance in demanding industrial applications where loosening under dynamic loads poses significant reliability risks. The 18-8 stainless steel construction provides exceptional corrosion resistance, making it ideal for chemical processing, marine environments, and food processing equipment where moisture and corrosive elements are present. The wave split design creates continuous spring tension that compensates for material relaxation and thermal cycling, maintaining bolt preload in vibrating machinery, automotive assemblies, and precision equipment. Manufactured to DIN 128B specifications, these metric lock washers ensure dimensional accuracy and consistent performance across production runs, reducing assembly issues and maintenance requirements in high-vibration industrial settings.

Specification Summary & Compliance

This wave split lock washer features precise metric dimensions with 4.4mm internal diameter, 7.6mm outer diameter, and 0.7mm thickness, engineered specifically for M4 screw applications. The product conforms to DIN 128B standard specifications for dimensional accuracy and performance requirements. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and unrestricted use across global industrial markets, with verification against the latest SVHC list updated January 17, 2023.
