Professional Applications & Engineering Value

This 3/8"-16 UNC coupling nut delivers exceptional engineering value in demanding applications where corrosion resistance and mechanical reliability are critical. The 18-8 stainless steel composition provides excellent protection against rust and chemical degradation, making it suitable for marine, chemical processing, and outdoor industrial installations. The fully threaded design and Class 2B thread fit ensure maximum thread contact area, distributing load evenly across connected components to prevent stress concentration and joint failure. The UNC coarse threading facilitates quicker assembly in field applications while maintaining strong holding power. These coupling nuts effectively solve common challenges in extended fastener applications, shaft coupling, and plumbing systems where joining two threaded rods or pipes requires both durability and environmental compliance.

Specification Summary & Compliance

This coupling nut maintains Class 2B thread fit tolerance per UNC standards, ensuring precise thread engagement with mating components. The manufacturing strictly follows ASTM A582 specifications for material properties and dimensional accuracy. Environmental compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances. Key dimensions include 3/8"-16 UNC coarse threading, 31/64" OD, and 1 1/2" length with right-hand thread direction for standard industrial applications.
