Professional Applications & Engineering Value
This heavy-duty hex nut is engineered to address common industrial challenges such as corrosion-induced failures and inconsistent thread fits. The Black-Oxide 18-8 Stainless Steel provides excellent resistance to rust and oxidation, making it suitable for outdoor, marine, or chemical-exposed applications. Its coarse UNC threads and Class 2B thread fit ensure rapid assembly and secure fastening, reducing the risk of cross-threading in high-vibration environments like machinery, construction, and transportation equipment. The standard external hex drive allows for easy tool access, enhancing efficiency in tight spaces while maintaining reliable fastening performance in demanding conditions.
Specification Summary & Compliance
This hex nut features a 1 1/4"-7 UNC coarse thread with Class 2B thread fit for precise dimensional accuracy per inch system standards. It adheres to manufacturing specifications for standard hex nut profiles, with a width of 1 7/8" and height of 1 1/16". The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety requirements for industrial fasteners.
