Professional Applications & Engineering Value
This M8 split lock washer is engineered from 316 stainless steel, offering exceptional pitting and crevice corrosion resistance, which is critical in aggressive industrial settings like chemical processing, marine equipment, and food machinery. The split lock design provides continuous spring tension against the nut and bearing surface, effectively resisting vibration-induced loosening—a common failure point in dynamic assemblies. By conforming to DIN 7980, it ensures dimensional precision and reliability in metric fastener systems, reducing maintenance needs and downtime. Its RoHS and REACH compliance further supports use in environmentally conscious and regulated sectors, providing peace of mind for engineers specifying components for long-term, safe operation.
Specification Summary & Compliance
This washer meets DIN 7980 specifications for standard split lock washers, with an inner diameter of 8.5 mm, outer diameter of 12.7 mm, and thickness of 1.9-2.1 mm, designed for M8 screw size. It is manufactured from 316 stainless steel and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted substances for industrial safety and environmental responsibility.
