Professional Applications & Engineering Value

This M6 DIN 93 tab lock washer delivers critical engineering solutions for applications where vibration resistance is paramount. The 18-8 stainless steel construction provides exceptional corrosion resistance in demanding environments such as automotive assemblies, industrial machinery, and marine equipment. The tab lock design mechanically prevents rotational loosening, making it ideal for motors, engines, and vibrating machinery where traditional washers fail. The metric dimensions (6.4mm ID × 19mm OD × 0.5mm thickness) ensure precise fit with M6 fasteners while the Rockwell B70 hardness maintains structural integrity under repeated stress cycles. This combination of material properties and mechanical design addresses common failure points in industrial fastening systems.
