Professional Applications & Engineering Value

This extra long coupling nut addresses critical challenges in industrial assembly where standard fasteners fall short. The 8 1/2" length provides exceptional span capability for connecting threaded rods in construction, machinery framing, and structural applications. The steel construction ensures reliable performance under heavy loads and vibration, while the UNC coarse threading enables quick assembly without compromising strength. The external hex drive design allows for high-torque installation using common wrenches, making it ideal for maintenance and repair operations where access may be limited. This coupling solution is particularly valuable in piping systems, structural steel connections, and heavy equipment manufacturing where extended reach and Class 2B thread fit guarantee precise, secure connections that withstand operational stresses.

Specification Summary & Compliance

This coupling nut features 1 3/4"-5 UNC coarse threading with Class 2B thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and reliable mating compatibility. The partially threaded design and right-hand thread direction follow industry conventions for straightforward installation. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental responsibility and chemical safety compliance for industrial applications worldwide.
