Professional Applications & Engineering Value

These extra wide hex nuts engineered from hot-dipped galvanized steel address critical challenges in heavy industrial applications where corrosion resistance and load-bearing capacity are paramount. The 1 1/8"-8 coarse thread configuration with UN thread standard ensures rapid assembly in structural steel connections, bridge construction, and heavy machinery where vibration resistance is essential. The external hex drive design accommodates standard torque tools for efficient installation in confined spaces. Particularly valuable in marine environments, chemical processing plants, and outdoor infrastructure projects, these ASTM Grade 2H nuts maintain clamping force integrity while the zinc coating provides sacrificial protection against galvanic corrosion, significantly reducing maintenance frequency and replacement costs.

Specification Summary & Compliance

This hex nut features precise Class 2B thread fit tolerance with 1 1/8"-8 UNC coarse thread specification and right-hand thread direction. Manufacturing complies with ASTM A194 standard for dimensional consistency. The product meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations regarding SVHC management. Physical dimensions include 1 13/16" width across flats and 1 7/64" height, providing substantial bearing surface for ASTM Grade 2H strength classification in inch system applications.
