S-90264A233 5/8"-11 x 5" Coupling Nuts

Key Features & Benefits at a Glance

• Extended 5" length enables secure joining of long threaded rods or bolts with ample engagement for maximum load distribution
• Zinc-plated steel construction provides excellent corrosion resistance for extended service life in harsh industrial environments
• Class 2B thread fit ensures smooth assembly and reliable performance with standard 5/8"-11 UNC threaded components
• External hex drive design allows for high-torque installation using common wrenches without specialized tools
• Partially threaded configuration offers flexibility for precise positioning while maintaining full thread engagement
• Heavy-duty UNC coarse threading delivers superior vibration resistance and faster assembly in demanding applications
• Right-hand thread direction provides standard, intuitive installation compatible with most industrial fastening systems

Professional Applications & Engineering Value

This extra long coupling nut solves critical connection challenges in structural and mechanical assemblies where standard nuts cannot span the required distance. The zinc-plated steel material offers optimal strength-to-weight ratio while protecting against environmental degradation, making it ideal for construction frameworks, machinery linking, and infrastructure projects. The 5/8"-11 UNC coarse thread configuration ensures compatibility with common industrial components while providing exceptional resistance to loosening under dynamic loads. Engineers specify this heavy duty connector for applications requiring extended reach between threaded rods, particularly in suspension systems, structural bracing, and equipment mounting where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

This coupling nut maintains Class 2B thread fit per UNC standards with precise 5/8"-11 coarse threading for consistent performance. Manufacturing complies with industry standards for external hex drive fasteners and partially threaded components. The product fully meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations regarding chemical safety, ensuring environmental responsibility and workplace safety compliance.
