Professional Applications & Engineering Value

This hot-dipped galvanized steel hex nut delivers exceptional engineering value for industrial applications where corrosion resistance and mechanical reliability are paramount. The Grade 2 strength classification provides optimal performance for structural connections, machinery assembly, and equipment manufacturing where medium-duty fastening is required. The coarse UNC thread profile combined with Class 2B thread fit ensures rapid installation and secure mating with corresponding bolts, significantly reducing assembly time in production environments. The zinc coating from the hot-dip galvanizing process creates a sacrificial barrier that protects against rust and corrosion in outdoor applications, chemical processing facilities, and marine-adjacent installations. Engineered to ASME B18.2.2 specifications, this hex nut maintains dimensional consistency across batches, critical for maintenance operations and replacement part programs in industrial settings.

Specification Summary & Compliance

This hex nut features precise Class 2B thread fit with 3/4"-10 UNC coarse threading in right-hand direction, manufactured to exact ASME B18.2.2 dimensional standards. The fastener meets Grade 2 strength requirements and demonstrates full compliance with RoHS 3 (2015/863/EU) environmental directives. With standard hex profile measuring 1 1/8" across flats and 41/64" height, this inch-system nut ensures proper torque transmission and reliable performance in industrial fastening systems.
