Professional Applications & Engineering Value

This M5 spring lock washer delivers critical vibration-damping performance for industrial machinery, automotive assemblies, and marine equipment where constant motion threatens joint integrity. The curved DIN 137A design creates continuous spring tension that compensates for thermal expansion, material relaxation, and impact forces. Manufactured from 316 stainless steel, this metric spring washer resists chloride-induced corrosion in chemical processing, offshore, and food industry applications. The precise 5.3mm ID ensures perfect alignment with M5 fasteners while the 10mm OD distributes clamping force evenly, preventing surface damage to sensitive components. This combination of vibration-resistant engineering and corrosion-proof materials solves the dual challenges of mechanical loosening and environmental degradation in demanding industrial applications.

Specification Summary & Compliance

This spring lock washer meets DIN 137A specifications with precise metric dimensions: 5.3mm internal diameter, 10mm outer diameter, 0.5mm thickness, and 1.8mm overall height, engineered for M5 screw applications. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance. The 316 stainless steel construction provides consistent mechanical properties without hardness rating requirements, making it suitable for various industrial fastening systems where corrosion resistance and spring tension maintenance are critical.
