Professional Applications & Engineering Value
This Grade 2 zinc-plated steel coupling nut delivers critical engineering solutions for industrial assembly challenges where extended-length fastening is required. The fully threaded UNC coarse thread configuration maintains consistent load transfer across the entire 1½" length, preventing stress concentration points that compromise joint integrity. The external hex drive accommodates standard torque tools for precise installation in confined spaces, while the 3/16" sight hole enables visual verification of proper thread engagement - eliminating guesswork in critical connections. Manufactured from zinc-plated steel, this coupling nut resists environmental degradation in manufacturing, construction, and machinery applications where corrosion protection is essential for long-term reliability.
Specification Summary & Compliance
This coupling nut maintains Class 2B thread fit tolerances per UNC standards with 1/2"-13 coarse threading and right-hand thread direction. The 3/4" width across flats ensures compatibility with standard wrench sizes. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, confirming adherence to international environmental and safety regulations for industrial components.
