Professional Applications & Engineering Value

This heavy-duty brass coupling nut addresses critical engineering challenges in industrial assembly where corrosion resistance and thread reliability are paramount. The 1 1/2"-6 UNC coarse threading with Class 2B fit ensures precise alignment and secure connections in high-vibration environments, preventing loosening under dynamic loads. The fully threaded design maximizes surface contact area, distributing stress evenly across the entire 3.5" length to prevent thread stripping and connection failure. Manufactured from premium brass material, this coupling nut withstands exposure to moisture, chemicals, and temperature variations common in plumbing, marine, and industrial machinery applications. The external hex drive facilitates quick installation with standard tools, reducing assembly time while maintaining the integrity of critical connections in piping systems, structural frameworks, and equipment manufacturing.

Specification Summary & Compliance

This coupling nut features precision 1 1/2"-6 UNC coarse threading with Class 2B thread fit according to standard inch measurement specifications. The component maintains dimensional accuracy with 2" width across flats and 3.5" length for consistent performance. Manufacturing complies with REACH (EC 1907/2006) regulations regarding substance restrictions and RoHS 3 (2015/863/EU) compliance with exemption 6(c) for lead in copper alloys. The right-hand thread direction and standard coupling profile ensure compatibility with industry-standard components and assembly requirements.
