Professional Applications & Engineering Value

This extra long coupling nut delivers critical engineering solutions where extended reach and maximum thread engagement are paramount. The 18-8 stainless steel construction provides exceptional corrosion resistance, making it ideal for chemical processing, marine, and outdoor industrial applications where environmental factors degrade ordinary fasteners. The UNF fine threading with Class 2B fit ensures precise alignment and vibration resistance in machinery, structural frameworks, and precision equipment. The partially threaded design optimizes stress distribution across the connection point, while the external hex drive facilitates installation in space-constrained assemblies. This coupling nut serves as a reliable connecting solution for joining long threaded rods, extending shaft lengths, or creating custom-length fastening systems in construction, manufacturing, and heavy equipment applications.

Specification Summary & Compliance

This coupling nut features 3/4"-16 UNF fine threading with Class 2B thread fit per UNF standards, ensuring precise dimensional accuracy and compatibility. The partially threaded construction provides minimum thread length of 3/4" with overall dimensions of 1 1/8" width and 5" length. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental compliance for industrial applications. The inch system measurement and right-hand thread direction maintain consistency with North American industrial standards for seamless integration into existing fastener systems.
