Professional Applications & Engineering Value

This M12 nylon insert lock cap nut delivers exceptional engineering value in demanding industrial environments where vibration loosening poses significant reliability concerns. The zinc-plated steel construction provides essential corrosion resistance while maintaining Class 6 strength rating for medium-duty applications. The nylon insert locking mechanism creates consistent friction against mating threads, effectively dampening vibrations in automotive assemblies, machinery frames, and industrial equipment. With its metric coarse threading (1.75mm pitch) and standard hex profile, this fastener ensures quick installation and removal while the cap nut design provides both aesthetic finishing and protection for exposed thread ends. The combination of DIN 986 compliance and temperature-resistant nylon insert makes this nut particularly valuable for applications requiring repeated maintenance access without compromising locking performance.

Specification Summary & Compliance

This M12 x 1.75mm cap nut features Class 6H thread fit per ISO metric standards with coarse thread spacing and right-hand direction. Manufactured to DIN 986 specifications with external hex drive, 18mm width, and 23mm height dimensions. The fastener meets Class 6 strength rating requirements and incorporates an 8.3mm thread depth. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for various industrial applications while maintaining dimensional precision and performance consistency.
