Professional Applications & Engineering Value

This brass coupling nut solves critical connectivity challenges in industrial assemblies where corrosion resistance and precision threading are paramount. The UNF fine thread configuration with Class 2B fit ensures zero play in high-vibration environments, while the external hex drive facilitates quick installation in tight spaces. Engineered for heavy-duty applications including hydraulic systems, precision machinery, and marine equipment, the fully threaded design provides maximum tensile strength and uniform stress distribution. The brass material naturally resists galvanic corrosion, making it ideal for connecting dissimilar metals in chemical processing and outdoor installations.

Specification Summary & Compliance

This coupling nut maintains Class 2B thread fit per UNF standards with 9/16"-18 fine threading and right-hand direction. Manufacturing complies with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloys. Dimensions include 2 1/8" length and 13/16" width with external hex drive profile, ensuring consistent performance in inch-system assemblies.
