Professional Applications & Engineering Value
This M45 DIN 462 spring lock washer addresses critical vibration-induced loosening challenges in heavy machinery, automotive assemblies, and industrial equipment. The conical spring design creates continuous axial force that compensates for settlement and thermal expansion, while the stepped bearing nut face style provides positive locking action against rotational forces. Manufactured from high-quality steel, this metric lock washer maintains its spring characteristics through repeated loading cycles, making it ideal for applications where vibration resistance is paramount. The precise 45mm internal diameter and 68mm outer diameter ensure perfect alignment with M45 fastening systems, reducing installation time and improving assembly reliability in manufacturing and maintenance operations.
Specification Summary & Compliance
This spring lock washer conforms to DIN 462 standards for dimensional accuracy and performance requirements, with precise metric measurements including 45mm ID, 68mm OD, and 1.2mm thickness. The washer is compatible with DIN 1804 bearing nut specifications and designed for M45 screw applications. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring the product meets current international environmental standards for industrial fasteners.
