Professional Applications & Engineering Value
This extra long coupling nut delivers critical engineering solutions where standard fasteners fall short. The zinc-plated steel construction provides essential corrosion protection for industrial environments exposed to moisture or chemicals, while the 7 1/2" length enables connections between widely spaced components in structural frameworks, machinery assembly, and construction applications. The UNC coarse threading ensures rapid installation and reliable performance in high-vibration environments, with the external hex drive allowing for precise torque application during installation. Particularly valuable in heavy-duty applications requiring extended reach between threaded rods, this coupling nut maintains structural integrity while simplifying complex assembly challenges where accessibility is limited.
Specification Summary & Compliance
This coupling nut features 1 1/4"-7 UNC coarse threading with Class 2B thread fit for precise dimensional accuracy and reliable performance. The partially threaded design and external hex drive configuration ensure optimal functionality across industrial applications. Manufactured to industry standards with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and safety requirements for industrial fastener applications.
