Professional Applications & Engineering Value
This M8 spring lock washer is engineered to solve critical vibration-induced loosening in industrial machinery, automotive assemblies, and heavy-duty equipment. The curved lock washer design applies continuous spring tension, compensating for thermal expansion and dynamic stresses that cause fastener failure. Made from zinc-plated steel, it resists corrosion in humid or chemically aggressive environments, while the Rockwell C42 hardness ensures the washer retains its shape under repeated loading cycles. By adhering to DIN 137A specifications, it delivers predictable performance in metric fastening systems, reducing maintenance downtime and enhancing operational safety in applications from conveyor systems to structural frameworks.
Specification Summary & Compliance
This washer meets DIN 137A dimensional and performance standards, with precise metric measurements: 8.4mm ID, 15mm OD, 0.5mm thickness, and 3.4mm overall height. It is manufactured from zinc-plated steel and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and safe for industrial use globally.
