Professional Applications & Engineering Value

This M3 conical spring lock washer delivers critical engineering solutions for vibration-prone applications where fastener loosening can compromise system integrity. The black-phosphate steel construction provides essential corrosion resistance while the conical shape creates continuous spring force that counters vibrational stresses in machinery, automotive assemblies, and electrical enclosures. Engineered to DIN 6796 specifications, these metric spring washers maintain clamping force through their unique geometry, preventing joint failure in dynamic loading conditions. The precise 3.2mm internal diameter ensures perfect alignment with M3 screws, while the 7mm outer diameter provides optimal bearing surface for distributed load transmission across connected components.
