Professional Applications & Engineering Value
This 6061 aluminum coupling nut delivers exceptional engineering value through its heavy-duty construction and precision UNC coarse threading. The external hex drive enables high-torque installation without compromising the aluminum material integrity, while the Class 2B thread fit ensures smooth engagement and reliable performance in industrial applications. The fully threaded design maximizes strength across the entire 1 1/4" length, making it ideal for connecting threaded rods, extending existing threads, or creating custom-length fasteners in machinery, structural frameworks, and equipment assembly where lightweight durability and corrosion resistance are critical operational requirements.
Specification Summary & Compliance
This coupling nut features precision 1/2"-13 UNC coarse threading with Class 2B thread fit tolerance for reliable engagement. Manufactured to industry standards with external hex drive and standard coupling nut profile measuring 5/8" width and 1 1/4" length. Fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) standards with exemption 6(b)-II for lead as an alloying element in aluminum machining applications.
