Value Collection 313490BR Heavy Hex Nut 1-1/2-6 Galvanized

Product Description

The VALUE COLLECTION 313490BR is a heavy hex nut manufactured from A194 Grade 2H steel with a hot-dipped galvanized finish. It is designed for use in structural bolting applications where increased bearing surface and higher load resistance are required compared to standard hex nuts. The 1-1/2-6 UNC thread size and right-hand thread direction make it compatible with standard threaded rod, anchor bolts, and heavy structural fasteners. The hot-dipped galvanized coating provides corrosion resistance for outdoor, wet, or moderately corrosive environments. Licensed tradespeople and structural contractors working on industrial, commercial, and infrastructure projects are the primary installers of this fastener type.

This heavy hex nut is used in structural steel connections, pressure vessel assembly, pipeline flanges, and heavy equipment mounting. The A194 Grade 2H designation identifies it as a carbon steel nut rated for high-strength bolting applications, commonly specified alongside ASTM A193 Grade B7 threaded studs and bolts. It is appropriate for both above-grade and below-grade applications where galvanized corrosion protection meets project specifications.

Key Features

• A194 Grade 2H carbon steel construction rated for high-strength structural bolting
• Hot-dipped galvanized finish for corrosion resistance in outdoor and wet environments
• Heavy hex profile provides greater width across flats and bearing surface than standard hex nuts
• Right-hand UNC thread standard for compatibility with standard threaded fasteners
• 2-3/8 inches across flats for use with heavy-duty wrench or impact tooling

Compatibility

Designed as an OEM-style replacement or new-installation heavy hex nut for structural and industrial bolting applications using 1-1/2-6 UNC threaded fasteners.

Installation Notes

Installation should be performed by qualified tradespeople following applicable structural or mechanical codes such as AISC, ASME, or project-specific engineering specifications. Always confirm thread engagement length and torque requirements per the applicable engineering standard before final tightening. Use appropriately rated wrenches or impact tools sized for 2-3/8 inches across flats. Inspect the galvanized coating for damage before installation; compromised coating may reduce corrosion protection in exposed environments.
