Professional Applications & Engineering Value
This M170 metric spring lock washer delivers critical vibration resistance in heavy-duty industrial applications where fastener integrity is paramount. The conical steel construction and external teeth design work synergistically to prevent loosening under extreme vibration and thermal cycling, addressing common failure points in machinery, automotive assemblies, and structural frameworks. Engineered to DIN 5406 standards with a chamfered bearing nut face, this washer ensures proper alignment and distribution of clamping forces, reducing stress concentrations that lead to joint failure. The 2.5mm thickness and 11.5mm overall height provide optimal spring action while maintaining compact installation profiles, making it ideal for space-constrained applications requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
This metric spring lock washer features precise dimensional specifications including 170mm internal diameter, 232mm external diameter, 2.5mm thickness, and 11.5mm overall height with 18mm tab width and 6mm tab depth. Manufactured to DIN 5406 standards with compatibility for DIN 981 bearing nuts, the washer ensures dimensional accuracy and functional reliability. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components.
