Professional Applications & Engineering Value
This extra long coupling nut solves critical challenges in industrial assembly by providing a robust connection point for threaded rods and piping systems. The 18-8 stainless steel material delivers excellent corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or outdoor elements where ordinary fasteners would fail. The 4" length and partially threaded design allow for deep engagement and adjustment flexibility, while the coarse UNC thread ensures quick assembly even in challenging conditions. Engineered with Class 2B thread fit, this coupling nut maintains precise tolerances for vibration resistance and long-term reliability in construction, manufacturing, and infrastructure projects where joint integrity is paramount.
Specification Summary & Compliance
This coupling nut features 3/4"-10 UNC coarse threading with Class 2B thread fit for consistent dimensional accuracy. The external hex drive measures 1-1/8" across flats with a total length of 4" and minimum thread length of 3/4". Manufactured from 18-8 stainless steel, this fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for industrial applications worldwide.
