S-90264A242 3/4"-10 x 1 1/2" Coupling Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in harsh industrial environments
• Enhanced load distribution through full-length threading, preventing stress concentration and joint failure
• Precise thread engagement with Class 2B fit ensuring reliable connections in high-vibration applications
• Quick installation using standard external hex drive, compatible with common wrench tools
• Robust coarse threading (10 UNC) resisting cross-threading and enabling faster assembly cycles
• Regulatory compliance meeting RoHS 3 and REACH standards for global industrial safety requirements
• Optimized dimensions (1¼" width × 1½" length) providing balanced strength-to-weight ratio for structural applications

Professional Applications & Engineering Value

This heavy-duty coupling nut solves critical alignment challenges in industrial assembly lines and structural frameworks. The zinc-plated steel construction combats corrosion in manufacturing facilities, while the fully threaded UNC coarse pattern maintains integrity under dynamic loads. Engineers specify the Class 2B thread fit for precision joining of threaded rods in mechanical systems, eliminating play in vibration-prone equipment. The external hex drive enables high-torque installation in confined spaces, making it ideal for construction machinery and material handling systems requiring reliable long-thread engagement.

Specification Summary & Compliance

Manufactured to UNC coarse thread standards with Class 2B thread fit tolerances for consistent mating with Class 2A external threads. Dimensions precisely maintained at 1¼" width across flats and 1½" length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety protocols for industrial components.
