Professional Applications & Engineering Value
This M20 split lock washer delivers critical engineering solutions for vibration-prone assemblies where fastener loosening compromises safety and performance. The 18-8 stainless steel construction provides inherent corrosion resistance, making it ideal for chemical processing, marine equipment, and food machinery where moisture and corrosive agents are present. The DIN 127B standard ensures precise dimensional tolerances and consistent spring tension, while the split lock design creates continuous radial pressure that counters rotational forces in dynamic systems. These metric lock washers are particularly valuable in automotive subassemblies, industrial machinery, and electrical enclosures where vibration damping and maintained clamp load are essential for operational reliability and reduced maintenance intervals.
Specification Summary & Compliance
Manufactured to DIN 127B specifications with precise metric dimensions: 21.2mm inner diameter, 33.6mm outer diameter, and 3.8-4.2mm thickness range. The 18-8 stainless steel construction meets industry standards for corrosion resistance and mechanical properties. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and global market acceptance. Designed specifically for M20 screw sizes with standard split lock washer configuration for reliable fastening performance in industrial applications.
