Professional Applications & Engineering Value
This heavy-duty coupling nut delivers critical engineering value in applications requiring extended thread connections between male-threaded components. The zinc-plated steel construction provides essential corrosion protection for industrial equipment, machinery, and structural assemblies exposed to demanding environmental conditions. The 1 1/8"-7 UNC coarse threading with Class 2B fit ensures reliable engagement in high-vibration environments where thread security is paramount. The fully threaded design accommodates various connection depths while the standard external hex profile enables straightforward installation using common tools. This coupling nut solves connection length challenges in pipe systems, structural frameworks, and heavy machinery where standard nuts cannot bridge the required distance between threaded rods or studs.
Specification Summary & Compliance
This coupling nut features 1 1/8"-7 UNC coarse threading with Class 2B thread fit per ASME standards, ensuring precise dimensional accuracy and reliable performance. The zinc-plated steel construction provides durable corrosion resistance while maintaining high tensile strength. With dimensions of 1 1/2" width and 3" length, this fully threaded coupling nut with right-hand direction meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for environmental safety in industrial applications.
