- 18-8 stainless steel construction delivers excellent corrosion resistance and durability in harsh environments
- External hex drive design enables easy installation and removal with standard wrenching tools
- Class 2B thread fit ensures smooth, reliable assembly with consistent mating performance
- Partially threaded configuration offers optimal balance between thread engagement and installation efficiency
- RoHS 3 and REACH compliance guarantees environmental responsibility and regulatory adherence for global projects
- UNC coarse threading provides rapid assembly and reduced cross-threading risks in industrial applications
Professional Applications & Engineering Value
This extra long coupling nut solves critical alignment and connection challenges in precision assemblies where standard nuts fall short. The 5/8" length and partially threaded design allow for extended reach applications while maintaining optimal thread distribution. Engineered with 18-8 stainless steel, it withstands corrosive environments common in marine, chemical processing, and outdoor installations. The external hex drive accommodates high-torque applications without stripping, while the UNC coarse threads ensure rapid assembly in production environments. Ideal for connecting threaded rods, extending shafts, or joining components where vibration resistance and long-term reliability are paramount in mechanical systems, industrial equipment, and structural frameworks.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2B thread fit for consistent mating performance. Features 2-56 UNC coarse threading with right-hand direction and partially threaded configuration (minimum 3/16" thread length). Dimensions include 1/4" width across flats and 5/8" total length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for international industrial applications.
