Professional Applications & Engineering Value

This heavy-duty hex nut is engineered to address common industrial challenges such as joint failure under dynamic loads and time-consuming installations. The extra-wide thin profile and 2" width significantly increase the bearing surface area, which helps distribute clamping force more evenly and prevents damage to connected materials. Made from Grade 2 steel, it offers an optimal balance of strength and ductility for applications in construction machinery, agricultural equipment, and structural frameworks where reliability is critical. The 1 1/4"-7 UNC coarse thread and Class 2B thread fit ensure quick engagement and reduced cross-threading risks, while the external hex drive allows for high-torque application with standard tools, enhancing productivity in assembly lines and field maintenance.

Specification Summary & Compliance

This hex nut adheres to Class 2B thread fit tolerances under the Unified National Coarse (UNC) standard, ensuring consistent thread engagement and interchangeability. It is manufactured in accordance with Grade 2 strength specifications for inch-system fasteners, with dimensions of 2" width and 23/32" height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted hazardous substances and supporting sustainable procurement practices.
