S-90264A706 2"-4 1/2 x 9" Coupling Nuts

Key Features & Benefits at a Glance

• Extended grip length provides superior thread engagement for secure connections in demanding structural applications
• Heavy-duty steel construction ensures exceptional tensile strength and durability under high-load conditions
• Class 2B thread fit guarantees smooth assembly and reliable performance with standard UNC threaded components
• External hex drive design enables easy installation and removal with common wrench tools
• Partial threading configuration optimizes weight distribution while maintaining full functional integrity
• Coarse UNC thread pattern resists vibration loosening and minimizes cross-threading risks
• Full regulatory compliance meets international environmental and safety standards for industrial use

Professional Applications & Engineering Value

This extra long coupling nut solves critical connection challenges in heavy machinery, structural steel frameworks, and industrial piping systems where standard nuts cannot provide sufficient thread engagement. The 9-inch length and partially threaded design allow for extended reach applications while maintaining structural integrity. Manufactured from high-grade steel with UNC coarse threading, this component delivers reliable performance in vibration-prone environments, preventing unexpected disconnections in critical assemblies. The external hex drive ensures compatibility with standard industrial tools, streamlining installation in confined spaces common in construction and manufacturing settings.

Specification Summary & Compliance

This coupling nut features precise Class 2B thread fit per UNC standards with coarse thread spacing for optimal performance. The component measures 3 1/4" in width and 9" in length with 2"-4 1/2 UNC threading in right-hand direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance standards are met for global applications.
