S-90268A224 1/2"-13 x 6" Coupling Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Exceptional length and strength with 6" extra long profile for connecting longer threaded rods securely
• Precise thread engagement with Class 2B thread fit ensuring reliable, vibration-resistant connections
• Optimized installation efficiency through external hex drive design for easy wrench access and torque application
• Reduced material usage with partial threading while maintaining full mechanical performance
• Broad compatibility with UNC coarse thread standards for versatile industrial applications
• Regulatory compliance assurance meeting RoHS 3 and REACH environmental standards

Professional Applications & Engineering Value

This extra long coupling nut solves critical challenges in industrial assembly where extended reach and robust connections are essential. The 18-8 stainless steel construction provides excellent corrosion resistance, making it suitable for chemical processing, marine, and outdoor applications where environmental factors degrade ordinary fasteners. The partially threaded design reduces material weight while maintaining full tensile strength, and the external hex drive allows for high-torque installation in confined spaces. With UNC coarse threading and Class 2B thread fit, it delivers reliable performance in vibration-prone machinery, structural frameworks, and heavy equipment where thread disengagement risks must be minimized.

Specification Summary & Compliance

This coupling nut features 1/2"-13 UNC coarse threading with Class 2B thread fit for precision tolerance, partial threading with minimum 5/8" thread length, and dimensions of 3/4" width × 6" length. Manufactured to standard industrial specifications, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability.
