Professional Applications & Engineering Value

This heavy hex nut delivers exceptional engineering value through its hot-dipped galvanized steel construction and extra wide profile, specifically designed to address critical industrial challenges. The robust ASTM A194 Grade 2H certification ensures reliable performance in structural applications, power generation equipment, and heavy machinery where vibration resistance and long-term durability are paramount. The coarse UNC threads provide superior engagement in materials prone to galling, while the substantial bearing surface distributes clamp load effectively, preventing joint relaxation in high-vibration environments. The external hex drive facilitates quick installation with standard tools, making it ideal for construction, bridgework, and industrial maintenance applications requiring both corrosion protection and heavy-duty performance.

Specification Summary & Compliance

This heavy hex nut maintains precise Class 2B thread fit tolerances according to UNC coarse thread standards with 5/8"-11 thread size. Manufactured to ASTM A194 Grade 2H specifications for high-strength applications, the fastener demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Dimensional accuracy is maintained at 1-1/16" width and 39/64" height, ensuring consistent performance across industrial applications requiring inch system fasteners with right-hand threading.
