Professional Applications & Engineering Value

This M2 spring lock washer delivers critical vibration resistance in precision assemblies where loosening under dynamic loads poses significant reliability risks. The curved design creates continuous spring tension that compensates for thermal expansion, material relaxation, and mechanical vibrations in applications ranging from electronic enclosures to small machinery components. Manufactured from zinc-plated steel, it provides essential corrosion protection while maintaining the Rockwell C42 hardness necessary for repeated compression cycles. The metric dimensions (2.2mm ID, 4.5mm OD) ensure perfect compatibility with M2 fasteners in industrial equipment, automotive subsystems, and precision instruments where space constraints demand reliable, compact locking solutions.
