S-90264A437 1/4"-20 x 1 1/2" Coupling Nuts

Key Features & Benefits at a Glance

• Exceptional length provides extended reach for connecting threaded rods or studs in hard-to-access assembly applications
• Zinc-plated steel construction delivers reliable corrosion resistance for extended service life in demanding industrial environments
• Class 2B thread fit ensures smooth, precise engagement with mating components while maintaining consistent torque performance
• Full threading design allows for maximum adjustability and positioning flexibility along the entire nut length
• External hex drive style enables easy installation and removal using standard wrenching tools
• UNC coarse threading provides quick assembly and disassembly while resisting vibration-induced loosening
• Compliance with RoHS 3 and REACH regulations guarantees environmental responsibility and workplace safety standards

Professional Applications & Engineering Value

This extra long coupling nut solves critical spacing challenges in industrial assembly where standard nuts cannot bridge the gap between components. The zinc-plated steel construction provides essential corrosion protection for applications exposed to moisture or harsh conditions, while the fully threaded design and 1 1/2" length offer unparalleled adjustability for precision alignment of machinery components, hydraulic systems, and structural frameworks. The 1/4"-20 UNC coarse thread configuration ensures rapid installation in production environments and maintains secure connections under vibration, making it ideal for conveyor systems, equipment mounting, and mechanical linkages where reliability is paramount. The external hex drive accommodates high-torque applications while the Class 2B thread fit guarantees consistent performance across multiple assembly cycles.

Specification Summary & Compliance

This coupling nut features 1/4"-20 UNC coarse threads with Class 2B thread fit tolerance for precise mating compatibility. The external hex measures 7/16" across flats with a total length of 1 1/2". Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance and restricted substance management for global industrial applications. The right-hand threaded, fully threaded configuration maintains consistent thread engagement throughout the entire nut length.
