Professional Applications & Engineering Value
This M48 DIN 127B split lock washer delivers critical engineering solutions for industrial applications where vibration-induced fastener failure is a primary concern. The zinc-plated steel construction provides essential corrosion resistance while maintaining the Rockwell C44 hardness required for heavy-duty mechanical assemblies. The split lock design creates continuous spring tension that compensates for thermal expansion, material relaxation, and dynamic loads in machinery, conveyor systems, and structural frameworks. Engineered to DIN 127B standards, this metric lock washer ensures precise dimensional accuracy (50.5mm ID/75mm OD) for perfect compatibility with M48 fasteners in automotive, manufacturing, and construction applications where reliable, long-term fastening security is non-negotiable.
Specification Summary & Compliance
Manufactured to DIN 127B specifications with precise internal diameter (50.5mm), outer diameter (75mm), and thickness (6.8-7.2mm) tolerances. The standard split lock washer design ensures consistent performance across metric fastening systems. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting international environmental and safety standards for industrial components. Material certification confirms zinc-plated steel construction with Rockwell C44 hardness verification for guaranteed mechanical properties.
