Value Collection 313200BR Heavy Hex Nut 3/4-10 A194 2H Galvanized

Product Description

The VALUE COLLECTION 313200BR is a heavy hex nut designed for high-strength bolted connections in structural, industrial, and mechanical applications. Manufactured to A194 Grade 2H specifications, this nut is made from carbon steel and carries a hot-dipped galvanized finish for corrosion resistance in outdoor and high-moisture environments. The heavy hex pattern provides a larger bearing surface than a standard hex nut, making it well suited for high-load fastener assemblies. Installation is performed by millwrights, ironworkers, pipefitters, and general contractors working with structural steel, pressure flanges, and heavy equipment.

This heavy hex nut is used in structural steel construction, industrial piping systems, and heavy equipment assembly where A194 Grade 2H compliance is required. The 3/4-10 UNC thread size and right-hand thread direction make it compatible with standard 3/4-inch threaded rod, bolts, and stud assemblies. The hot-dipped galvanized finish suits applications exposed to weather, moisture, or mildly corrosive conditions. It is a common fastener in bridge work, utility structures, and process piping installations.

Key Features

• A194 Grade 2H carbon steel construction for high-strength bolted joint applications
• Hot-dipped galvanized finish provides corrosion resistance in outdoor and wet environments
• Heavy hex pattern with 1-1/4 inches across flats for increased bearing surface and wrench engagement
• 3/4-10 UNC right-hand thread for compatibility with standard threaded fastener assemblies
• Height of 47/64 inches meets dimensional requirements for heavy hex nut specifications

Compatibility

Designed as an OEM-style replacement and general-use heavy hex nut for 3/4-10 UNC threaded fastener assemblies requiring A194 Grade 2H compliance.

Installation Notes

Heavy hex nuts of this grade are typically installed by qualified ironworkers, pipefitters, or millwrights following AISC, ASME, or applicable structural codes. Always verify thread engagement and ensure mating fasteners meet the same or compatible grade and thread standard before tensioning. Hot-dipped galvanized hardware should not be mixed with incompatible coatings or dissimilar metals in corrosion-sensitive joints. Follow torque requirements specified by the engineer of record or applicable code for the fastener assembly.
