Professional Applications & Engineering Value

This 3/8"-24 UNF coupling nut delivers critical engineering value in applications requiring extended thread engagement between male-threaded components. The zinc-plated steel construction provides essential corrosion protection for machinery, automotive, and structural assemblies exposed to environmental stressors. With Class 2B fine threading and full-length threads, this coupling nut maintains precise alignment while resisting loosening under vibration - a common failure point in industrial equipment. The external hex drive style enables high-torque installation without specialized tools, reducing assembly time in production environments. Engineered for inch-system compatibility, this component ensures seamless integration with existing UNF-threaded systems while meeting stringent RoHS and REACH compliance requirements for modern manufacturing.

Specification Summary & Compliance

This coupling nut features 3/8"-24 UNF fine threads with Class 2B thread fit per Unified Thread Standard specifications, ensuring precise dimensional accuracy and reliable performance. The component measures 1-3/4" in length with a 9/16" width across flats for standard tool engagement. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental safety standards for hazardous substance restrictions. The right-hand threaded, fully threaded design provides consistent mechanical properties throughout the coupling nut's entire length.
