Professional Applications & Engineering Value

This M14 nylon insert lock nut delivers critical vibration resistance in heavy machinery, automotive assemblies, and industrial equipment where loosening under dynamic loads poses significant safety risks. The zinc-plated steel construction provides essential corrosion protection while maintaining the Class 8 strength rating required for high-stress applications. The metric coarse threading (M14x2mm) ensures rapid installation and reliable engagement, while the nylon insert locking mechanism creates consistent friction that prevents back-off without damaging mating threads. Engineered to DIN 982 and ISO 7040 standards, this external hex locknut offers predictable performance and compatibility across international engineering specifications, making it ideal for OEM manufacturing and maintenance operations where vibration-induced failure is a primary concern.

Specification Summary & Compliance

This metric locknut features precise Class 6H thread fit with M14x2mm coarse right-hand threading and dimensional compliance with DIN 982 and ISO 7040 manufacturing standards. The component maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide. With a 22mm width and 16mm height profile, the nut delivers consistent dimensional accuracy for reliable assembly operations.
