Professional Applications & Engineering Value
Our M2.5x0.45mm extra long coupling nuts solve critical connection challenges in precision assemblies where standard nuts fall short. The zinc-plated steel construction provides superior corrosion protection in industrial settings, while the extended 12mm length offers exceptional thread engagement for joining threaded rods, studs, or bolts in mechanical linkages, electronic enclosures, and precision equipment. The Class 6H metric thread ensures precise fitment with mating components, eliminating play and reducing vibration-induced loosening. With fully threaded right-hand coarse pitch design, these coupling nuts deliver reliable performance in automated assembly lines, machinery maintenance, and OEM applications where consistent torque and secure fastening are paramount.
Specification Summary & Compliance
This extra long coupling nut features M2.5x0.45mm coarse metric thread with Class 6H tolerance for precision fitment. The external hex drive measures 4.5mm across flats with a 12mm length, manufactured from zinc-plated steel for corrosion resistance. Product complies with RoHS 3 (2015/863/EU) standards under exemption 6(a)-I for lead as an alloying element in steel, ensuring environmental regulatory compliance while maintaining mechanical performance requirements for industrial applications.
