Professional Applications & Engineering Value

This Grade 5 steel hex nut with extra wide profile addresses critical challenges in structural and heavy machinery applications. The 2" width significantly improves load distribution across fastened surfaces, reducing the risk of material deformation in high-vibration environments like construction equipment, agricultural machinery, and industrial conveyors. The coarse UNC threading and Class 2B thread fit provide reliable engagement even in dirty or corroded conditions, minimizing cross-threading issues during field maintenance. Engineered for external hex drive systems, it ensures maximum torque transfer without rounding, while the right-hand thread direction maintains compatibility with standard assembly protocols. This nut delivers consistent clamping force in demanding setups where joint integrity is non-negotiable.

Specification Summary & Compliance

This hex nut adheres to UNC coarse thread standards with precise Class 2B thread fit for consistent engagement and dimensional accuracy. Manufactured from Grade 5 steel for guaranteed mechanical properties, it meets industry specifications for inch-system fasteners. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and unrestricted use in global markets. The product maintains strict tolerance controls for thread size (1 1/4"-7), width (2"), and height (1 7/32") to ensure reliable performance in engineered assemblies.
