Professional Applications & Engineering Value
This 3/8"-16 UNC brass coupling nut solves critical connection challenges in industrial assemblies where corrosion resistance and thread reliability are paramount. The Class 2B thread fit prevents cross-threading while maintaining precise tolerances, reducing installation errors in high-vibration applications like machinery, plumbing, and electrical enclosures. The fully threaded design with coarse UNC threading provides maximum surface contact for distributing tensile and shear loads, while the external hex drive enables quick installation in confined spaces. Made from durable brass material, it resists galvanic corrosion when joining dissimilar metals, making it ideal for marine, chemical processing, and outdoor infrastructure projects requiring long-term reliability.
Specification Summary & Compliance
This coupling nut features 3/8"-16 UNC coarse threading with Class 2B thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy. The external hex drive measures 1/2" across flats with a 1 1/8" length for optimal engagement. Manufactured from brass with a standard profile, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting environmental and safety requirements for industrial components.
