Professional Applications & Engineering Value
This 316 stainless steel coupling nut delivers critical performance advantages in demanding industrial settings where corrosion resistance and mechanical strength are paramount. The fully threaded design maximizes engagement surface area, distributing stress evenly across the entire 3" length to prevent thread stripping under heavy loads. The 1 1/8"-7 UNC coarse threading with Class 2B fit ensures precise alignment and reliable torque transmission in piping systems, structural frameworks, and machinery assemblies. The external hex drive facilitates quick installation with standard tools, while the right-hand thread direction maintains compatibility with conventional fastening systems. Ideal for chemical processing, marine applications, and food processing equipment where 316 stainless steel's superior pitting resistance extends service life in corrosive environments.
Specification Summary & Compliance
This coupling nut features 1 1/8"-7 UNC coarse threading with Class 2B thread fit per ASME standards, ensuring precise dimensional accuracy and reliable performance. The 3" length and 1 1/2" width provide optimal engagement for extended connections. Manufactured from 316 stainless steel with standard coupling nut profile, the component is RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting current environmental and safety regulations for industrial applications.
