Professional Applications & Engineering Value
This M45 spring lock washer delivers critical vibration resistance in heavy machinery, automotive assemblies, and industrial equipment where constant motion and dynamic loads threaten fastener integrity. The external tooth configuration combined with the conical spring shape creates a dual-action locking mechanism that bites into both the nut and workpiece surface, effectively preventing rotational loosening under extreme conditions. Manufactured from high-quality steel and engineered to DIN 5406 standards, this metric spring lock washer addresses the common industrial challenge of maintaining bolted joint integrity in high-vibration environments. The precise 45mm inner diameter and 69mm outer diameter ensure optimal load distribution while maintaining compatibility with standard M45 fastening systems.
Specification Summary & Compliance
This spring lock washer conforms to DIN 5406 specifications with external tooth location and conical shape. The metric dimensional standards include 45mm inner diameter, 69mm outer diameter, and 4.5mm overall height with precise tab dimensions of 6mm width and 2.5mm depth. The washer is designed for compatibility with M45 screw sizes and DIN 981 chamfered bearing nuts. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across various industrial applications.
