Professional Applications & Engineering Value
This M30 split lock washer delivers critical vibration-damping performance for industrial machinery, automotive assemblies, and structural applications where dynamic loads threaten fastener integrity. The 18-8 stainless steel material maintains corrosion resistance in harsh environments while the DIN 7980 standard ensures precise dimensional control for consistent performance in metric fastener systems. The split lock mechanism creates continuous spring tension that compensates for material relaxation and thermal cycling, preventing catastrophic joint failure in vibration-prone applications. Engineered for M30 screw sizes with 31.7mm inner diameter, this washer provides reliable locking action without compromising installation efficiency in high-volume assembly operations.
Specification Summary & Compliance
Manufactured to DIN 7980 specifications with metric dimensions including 31.7mm inner diameter and 44.1mm outer diameter. Constructed from 18-8 stainless steel with thickness ranging 5.8-6.2mm. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in regulated industrial markets worldwide. Designed specifically for M30 screw applications where reliable locking performance and corrosion resistance are paramount.
