Professional Applications & Engineering Value
This M4 spring lock washer delivers exceptional engineering value through its black-phosphate steel construction and conical spring lock washer design, specifically engineered to combat vibration-induced loosening in industrial applications. The DIN 6796 compliant geometry creates continuous spring tension that compensates for thermal expansion, material relaxation, and dynamic loads. The black-phosphate surface treatment provides superior corrosion resistance without compromising the washer's spring properties, making it ideal for automotive assemblies, machinery, electrical enclosures, and heavy equipment where vibration resistant fastening is critical. The precise metric dimensions ensure perfect compatibility with M4 fasteners while maintaining reliable locking performance in high-cycle applications.
Specification Summary & Compliance
This spring lock washer features precise dimensional specifications with 4.3mm inner diameter, 9mm outer diameter, and 1.3mm overall height, manufactured to DIN 6796 standards for consistent performance. The product maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. The conical shape provides reliable spring action while the black-phosphate steel material offers both durability and corrosion protection for industrial fastener applications.
