Professional Applications & Engineering Value

This M35 Spring Lock Washer delivers exceptional engineering value through its DIN 5406 compliant design and external tooth configuration. The conical spring shape creates continuous spring tension that compensates for vibration-induced loosening, a critical failure point in machinery, automotive, and heavy equipment applications. Manufactured from high-quality steel, this metric spring lock washer provides reliable performance where thermal expansion, dynamic loads, and constant vibration challenge fastener integrity. The external tooth design ensures positive locking action by embedding into both the nut and bearing surface, creating mechanical resistance to rotational forces. This makes it ideal for vibration-resistant assemblies in manufacturing plants, construction equipment, and transportation systems where safety and reliability are paramount.
