Professional Applications & Engineering Value

This M18 spring lock washer delivers critical engineering solutions for industrial applications where vibration-induced fastener failure poses significant operational risks. The conical design creates continuous spring action that compensates for material relaxation and thermal expansion, maintaining clamping force in dynamic environments. Manufactured from 18-8 stainless steel, this DIN 6796 compliant washer offers excellent corrosion resistance for chemical processing, marine, and food industry applications. The precise metric dimensions (19mm ID × 42mm OD × 4.5mm thickness) ensure perfect compatibility with M18 fastening systems while the conical shape provides superior vibration resistance compared to flat washers. This makes it ideal for heavy machinery, automotive assemblies, and industrial equipment where reliable locking performance is non-negotiable.

Specification Summary & Compliance
