• Superior corrosion resistance thanks to 18-8 stainless steel construction, ideal for harsh industrial environments
• Reliable coarse threading with UNC 3/4"-10 Class 2B specification ensuring smooth assembly and vibration resistance
• Secure external hex drive design for easy installation using standard wrenches without stripping
• Partial threading optimization providing maximum grip strength while reducing material usage and weight
• Heavy-duty performance in demanding applications where extended length and durability are critical
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

This extra long coupling nut solves critical connection challenges in industrial assemblies where standard fasteners fall short. The 8-inch length bridges substantial gaps between threaded rods or pipes in construction, machinery, and structural frameworks. Manufactured from 18-8 stainless steel, it delivers exceptional corrosion resistance in chemical processing, marine, and outdoor applications. The UNC coarse threading with Class 2B fit ensures rapid installation and maintains integrity under vibration and dynamic loads. The partially threaded design concentrates material where strength matters most, while the external hex drive accommodates high-torque installation without specialized tools. This coupling nut provides engineering solutions for extended reach requirements while maintaining the reliability expected in heavy-duty industrial fastening applications.

Specification Summary & Compliance

This coupling nut features precision 3/4"-10 UNC coarse threading with Class 2B thread fit for consistent engagement and dimensional accuracy. The partial threading extends for a minimum of 3/4" with right-hand thread direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The 18-8 stainless steel construction meets industry standards for corrosion resistance and mechanical performance in demanding industrial coupling nut applications.
