Professional Applications & Engineering Value
This M18 conical spring lock washer delivers critical vibration resistance in demanding industrial applications where fastener security is paramount. The black-phosphate steel construction provides exceptional corrosion resistance, making it ideal for machinery, automotive assemblies, and outdoor equipment exposed to moisture and harsh conditions. The conical spring design creates continuous tension that compensates for material relaxation and thermal expansion, preventing catastrophic loosening in vibrating systems. Engineered to DIN 6796 specifications, this metric lock washer maintains reliable performance in heavy machinery, construction equipment, and manufacturing systems where M18 fasteners require secure, long-term locking solutions without compromising structural integrity.
Specification Summary & Compliance
This conical spring lock washer features precise metric dimensions with 19mm internal diameter, 42mm outer diameter, 4.5mm thickness, and 5.8mm overall height, specifically designed for M18 screw applications. Manufactured in compliance with DIN 6796 standards for dimensional accuracy and performance requirements. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations regarding substance restrictions, ensuring environmental safety and regulatory adherence for industrial procurement.
