• RoHS 3 and REACH compliance guarantees environmental responsibility and global regulatory acceptance

Professional Applications & Engineering Value

This extra long coupling nut solves critical connection challenges in industrial assembly where standard nuts fall short. The 18-8 stainless steel material provides inherent corrosion resistance for applications exposed to moisture, chemicals, or outdoor elements, while the 3" length accommodates extended spans between threaded components. The partially threaded UNC coarse thread design reduces binding during installation, making it ideal for production environments where speed and reliability are paramount. Engineering teams specify this heavy-duty coupling nut for machinery assembly, structural frameworks, and equipment maintenance where maximum connection strength and long-term durability are essential.

Specification Summary & Compliance

This coupling nut features 1/4"-20 UNC coarse threading with Class 2B thread fit for standard industrial compatibility. The partial threading extends to a minimum of 5/8" with overall dimensions of 1/2" width and 3" length. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental responsibility and regulatory acceptance for global industrial applications.
