• High-strength coarse threading using 9/16"-12 UNC specification for enhanced load distribution and vibration resistance in heavy-duty applications
• Optimized installation efficiency through external hex drive design allowing standard wrench access in confined spaces
• Partial threading design providing both threaded engagement sections and smooth shank areas for versatile connection requirements
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing and global market acceptance

Professional Applications & Engineering Value

This extra long coupling nut delivers critical engineering solutions where standard fasteners fall short. The 18-8 stainless steel construction provides exceptional corrosion resistance for demanding environments including chemical processing, marine applications, and outdoor structures. The 5" length and partially threaded design allow for adjustable connections between threaded rods while maintaining structural integrity. The 9/16"-12 UNC coarse thread configuration ensures rapid assembly and disassembly while providing superior vibration resistance in heavy machinery, construction frameworks, and piping systems. The external hex drive facilitates installation in tight spaces where socket access is limited, making it ideal for maintenance and repair operations across industrial sectors.

Specification Summary & Compliance

This coupling nut features Class 2B thread fit per UNC standards with 9/16"-12 coarse threading and right-hand thread direction. Dimensions include 5" length, 7/8" width across flats, and minimum thread length of 3/4". Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are met for industrial fastener applications.
