Professional Applications & Engineering Value
This heavy-duty hex nut is engineered to address common industrial challenges such as corrosion, vibration loosening, and high tensile stress. The hot-dipped galvanized steel construction provides a thick, uniform zinc layer that significantly extends service life in exposed or corrosive settings like construction, marine, and infrastructure projects. Its extra wide profile and 1"-8 UNC coarse thread design enhance grip and distribute clamping force more effectively, reducing the risk of joint failure. By meeting ASTM A194 and Grade 2H specifications, it ensures dependable performance in structural bolting, heavy machinery, and transportation equipment where reliability is critical.
Specification Summary & Compliance
This nut features precise Class 2B thread fit and UNC coarse thread with right-hand direction, adhering to inch system standards. Dimensions include a 1-5/8" width and 63/64" height for consistent compatibility. It complies with ASTM A194 for material and manufacturing requirements and ASTM Grade 2H for strength classification. Environmental compliance is confirmed with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring safety and sustainability in industrial use.
