Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this 1⅛"-7 UNC coupling nut solves critical connection challenges in structural assemblies, machinery, and construction projects. The hot-dipped galvanized steel construction provides exceptional corrosion protection, significantly extending service life in outdoor or corrosive environments where ordinary fasteners would fail. The fully threaded design with coarse UNC threads ensures maximum thread engagement across the entire 3" length, distributing loads evenly and preventing stress concentration points. The external hex drive allows for high-torque installation using standard wrenches, making it ideal for applications requiring robust connections in structural steel, heavy equipment, and industrial machinery where vibration resistance and long-term reliability are paramount.
Specification Summary & Compliance
This coupling nut features precise Class 2B thread fit with 1⅛"-7 UNC coarse threading and right-hand thread direction, manufactured to standard coupling nut profile specifications. The product maintains dimensional accuracy with 1½" width across flats and 3" length. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures adherence to environmental and safety standards for industrial applications.
