Key Features & Benefits at a Glance
- Extended 8" length provides superior reach for connecting threaded rods or pipes in hard-to-access industrial assemblies
- Heavy-duty steel construction ensures maximum load-bearing capacity and resistance to deformation under high-stress conditions
- Class 2B coarse UNC threading delivers faster assembly and reduced cross-threading risk compared to fine-thread alternatives
- Partially threaded design maintains structural integrity while allowing precise positioning adjustment during installation
- External hex drive style enables secure tool engagement for high-torque applications using standard wrenches
- Full RoHS 3 & REACH compliance guarantees environmental safety and regulatory acceptance in global industrial markets
- 2 1/4" hex width provides ample surface area for secure tool grip during installation and maintenance procedures
Professional Applications & Engineering Value
This extra long coupling nut solves critical connection challenges in structural, mechanical, and piping systems where standard nuts cannot span required gaps. The 1 3/8"-6 UNC coarse thread configuration ensures rapid installation in time-sensitive industrial maintenance scenarios, while the right-hand threaded, partially threaded design prevents over-tightening and maintains alignment accuracy. Manufactured from high-strength steel, this coupling nut withstands vibration, tension, and compression forces in heavy machinery, construction frameworks, and extended piping runs. The external hex drive accommodates both manual and powered tools, making it ideal for applications ranging from factory equipment assembly to infrastructure projects requiring reliable, long-span threaded connections.
Specification Summary & Compliance
This coupling nut maintains Class 2B thread fit per UNC standards, ensuring consistent engagement with mating components. Dimensions include 8" length and 2 1/4" width across flats with partially threaded, right-hand coarse threading. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting international environmental and safety standards for industrial components.
