S-90264A703 1 1/2"-6 x 8" Coupling Nuts

Key Features & Benefits at a Glance

• Extended 8" length enables secure joining of long threaded rods or pipes in structural applications
• Zinc-plated steel construction provides superior corrosion resistance for extended service life in harsh environments
• 1½"-6 UNC coarse threading with Class 2B fit ensures reliable engagement and vibration resistance in heavy-duty assemblies
• External hex drive design allows for high-torque installation using standard wrenches and sockets
• Partial threading configuration offers flexibility for precise positioning adjustments during assembly
• RoHS 3 and REACH compliance guarantees environmental safety and regulatory adherence for industrial projects
• 2⅜" hex width provides ample wrenching surface for secure installation and removal operations

Professional Applications & Engineering Value

This extra long coupling nut solves critical connection challenges in industrial frameworks where standard fasteners fall short. The zinc-plated steel construction combats corrosion in manufacturing facilities and outdoor installations, while the 8" length bridges significant gaps between threaded components in structural steel, machinery bases, and conveyor systems. The 1½"-6 UNC coarse thread with Class 2B fit maintains precise alignment under dynamic loads, preventing loosening in vibrating equipment. The external hex drive accommodates high-torque applications where socket access is limited, making it ideal for construction, heavy equipment maintenance, and infrastructure projects requiring heavy-duty fastening solutions.

Specification Summary & Compliance

This coupling nut features 1½"-6 UNC coarse threading with Class 2B thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and reliable performance. The partially threaded, right-hand configuration provides installation flexibility while maintaining structural integrity. Manufactured from high-strength steel with zinc plating for corrosion protection, this fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international industrial safety standards for hazardous substance restrictions.
