S-90264A114 3/8"-24 x 1 1/8" Coupling Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in harsh industrial environments
• Precise thread engagement through Class 2B thread fit, ensuring reliable connections without cross-threading
• Enhanced torque transmission via external hex drive design, allowing for secure installation with standard tools
• Optimal load distribution with fully threaded 1-1/8" length, maintaining joint integrity under tension
• Compatibility assurance with 3/8"-24 UNF fine threading, matching standard industrial components
• Environmental compliance meeting RoHS 3 and REACH standards, suitable for regulated applications
• Versatile coupling capability with standard profile design, connecting threaded rods or studs efficiently

Professional Applications & Engineering Value

This zinc-plated steel coupling nut solves critical alignment and extension challenges in mechanical assemblies where 3/8"-24 UNF fine threading is specified. The Class 2B thread fit provides consistent engagement with mating components, eliminating play in precision equipment while the external hex drive enables high-torque installation in confined spaces. Engineered for industrial coupling applications, it maintains structural integrity in conveyor systems, machinery frames, and hydraulic assemblies where vibration resistance and environmental compliance are mandatory. The fully threaded design distributes axial loads evenly across the entire 1-1/8" length, preventing stress concentration points that lead to fastener failure.

Specification Summary & Compliance

Manufactured to UNF thread standards with Class 2B thread fit tolerance for precise engagement. Dimensions include 3/8"-24 thread size with fine pitch, 1-1/8" length, and 1/2" width across flats. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances above threshold limits. Right-hand threaded coupling nut with standard profile for consistent performance in inch-system applications.
