Professional Applications & Engineering Value
This heavy-duty hex nut delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The ASTM Grade 7 steel construction provides exceptional tensile strength for demanding applications in construction machinery, industrial equipment, and structural frameworks. The extra wide profile significantly increases bearing surface area, distributing clamp load more effectively to prevent joint loosening under dynamic loads. With 1 1/8"-7 UNC coarse threads, this nut offers faster installation in thick materials while maintaining Class 2B thread fit precision for reliable performance in high-vibration environments. The combination of right-hand threading and external hex drive ensures compatibility with standard tools and simplifies maintenance procedures.
Specification Summary & Compliance
This industrial fastener features precise Class 2B thread fit per UNC standards with 1 1/8"-7 coarse thread spacing. Manufactured to ASTM A194 specifications using ASTM Grade 7 steel for guaranteed mechanical properties. Dimensions include 1 13/16" width across flats and 1 7/64" height. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for global industrial applications.
