Professional Applications & Engineering Value
Engineered for demanding industrial environments, this M18 metric split lock washer solves critical vibration-induced loosening challenges in machinery, automotive assemblies, and structural frameworks. The 18-8 stainless steel material provides inherent corrosion resistance, eliminating galvanic concerns in mixed-material applications while maintaining consistent performance in temperature-variable conditions. Its DIN 7980 standard compliance ensures precise dimensional control for reliable engagement with M18 screw fasteners, while the split lock mechanism creates continuous opposing force that compensates for thermal expansion and dynamic loading. This combination of vibration-resistant design and corrosion-proof materials makes it ideal for permanent installations where maintenance access is limited, reducing lifecycle costs through extended service intervals.
Specification Summary & Compliance
This split lock washer features a 19mm inner diameter, 26.4mm outer diameter, and 3.3-3.7mm thickness range, manufactured to DIN 7980 standards for dimensional precision. The standard split lock washer type provides reliable spring action for vibration resistance. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while meeting industrial fastener requirements for M18 applications.
