S-93525A301 3/8"-16 x 1 1/8" Coupling Nuts

Key Features & Benefits at a Glance

• Enhanced corrosion resistance through zinc-plated steel construction, extending service life in demanding industrial environments
• Superior load distribution with fully threaded design, maintaining consistent clamping force across connected components
• Quick and secure installation using standard wrench tools thanks to the external hex drive configuration
• Reliable thread engagement with Class 2B thread fit, ensuring smooth assembly and reduced cross-threading risks
• Robust mechanical performance meeting Grade 2 strength requirements for general purpose fastening applications
• Visual inspection capability through 1/8" sight hole, allowing verification of proper thread engagement during assembly
• Regulatory compliance assurance with REACH and RoHS 3 standards, meeting international environmental and safety requirements

Professional Applications & Engineering Value

This 3/8"-16 UNC coupling nut delivers critical engineering value by solving common extension and joining challenges in industrial assemblies. The zinc-plated steel construction provides essential corrosion protection for machinery, automotive, and structural applications where environmental exposure is a concern. The fully threaded design with coarse UNC threads ensures maximum thread contact area, distributing tensile loads evenly across connected rods or studs. The external hex drive enables high-torque installation using standard tools, while the 1 1/8" length provides sufficient engagement for secure connections. These features make it ideal for extending threaded rods, joining male-threaded components, and creating custom-length fastening solutions in manufacturing, construction, and maintenance operations.

Specification Summary & Compliance

This coupling nut features 3/8"-16 UNC coarse threads with Class 2B thread fit for standard industrial applications. Manufacturing conforms to Grade 2 strength classification with dimensions of 9/16" width and 1 1/8" length. The product is fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental safety and regulatory acceptance for industrial use across global markets.
