Professional Applications & Engineering Value
This extra long coupling nut solves critical connection challenges in industrial assembly where standard nuts fall short. The 4" zinc-plated steel body bridges significant gaps between threaded components while the 1/2"-13 UNC coarse threading maintains secure engagement across the extended length. Engineers specify this Class 2B thread fit coupling nut for structural frameworks, mechanical linkages, and piping systems where vibration resistance and alignment precision are paramount. The external hex drive accommodates high-torque installation, making it ideal for heavy-duty applications in construction, manufacturing, and equipment maintenance where reliable, long-span connections are essential for system integrity.
Specification Summary & Compliance
This coupling nut features 1/2"-13 UNC coarse threading with Class 2B thread fit per ASME B1.1 standards, ensuring dimensional accuracy and compatibility with Class 2A external threads. The 4" extra long profile with 7/8" width across flats provides substantial engagement surface. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and chemical substance restrictions adherence for industrial fastener applications.
