Professional Applications & Engineering Value

This M5 tab lock washer solves critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and electrical enclosures. The 18-8 stainless steel material provides inherent corrosion resistance for demanding environments where moisture or chemicals are present. The DIN 93 standard tab lock design creates mechanical interference that prevents rotational movement, making it ideal for motors, pumps, and vibrating equipment where traditional washers fail. The metric dimensions (5.3mm ID × 17mm OD × 0.5mm thickness) ensure precise fit with M5 fasteners while the 6mm tab width provides sufficient engagement surface for reliable locking performance in high-cycle applications.

Specification Summary & Compliance
