Professional Applications & Engineering Value

This Grade 5 steel hex nut delivers exceptional engineering value in demanding industrial environments where fastener failure is not an option. The extra-wide profile (1-7/16") significantly increases bearing surface area, effectively distributing clamping forces across a wider area to prevent material deformation and joint loosening under dynamic loads. The coarse UNC thread with Class 2B fit provides excellent resistance to vibration-induced loosening while accommodating minor misalignments during assembly. Manufactured from high-strength Grade 5 steel, this heavy-duty hex nut maintains its structural integrity in construction equipment, machinery frames, structural steel connections, and transportation applications where consistent performance under extreme conditions is critical. The combination of 55/64" height and right-hand threading ensures maximum thread engagement for secure, long-lasting fastening solutions.

Specification Summary & Compliance

This 7/8"-9 UNC hex nut features precision Class 2B thread fit with coarse thread spacing, manufactured to inch system standards. The fastener meets Grade 5 strength classification requirements and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Dimensions include 1-7/16" width across flats and 55/64" height, providing optimal proportions for heavy-duty industrial applications. The external hex drive configuration ensures compatibility with standard wrenching tools while maintaining dimensional accuracy throughout the manufacturing process.
