Professional Applications & Engineering Value
This M20 split lock washer solves critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and structural frameworks. The Black-Oxide 18-8 Stainless Steel construction provides dual protection: the base material offers excellent corrosion resistance while the oxide coating enhances surface durability and reduces galling. Engineered to DIN 127B standards, the washer maintains consistent spring action across temperature variations, ensuring reliable vibration resistance in dynamic loading conditions. The precise 21.2mm ID creates optimal interference fit with M20 fasteners, making it ideal for metric fastening systems in manufacturing equipment, transportation infrastructure, and marine applications where both chemical exposure and mechanical stress are concerns.
Specification Summary & Compliance
Manufactured to DIN 127B dimensional specifications with 21.2mm internal diameter, 33.6mm outer diameter, and 3.8-4.2mm thickness range. Constructed from 18-8 Stainless Steel with Black-Oxide surface treatment. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates. Designed specifically for M20 screw applications in metric measurement systems, ensuring proper fit and function in industrial fastening assemblies.
