Value Collection NDH087CGBPKGPR Hex Nut 7/8-9 Unc Galvanized

Product Description

The VALUE COLLECTION NDH087CGBPKGPR is a 7/8-9 UNC hex nut manufactured from A563 Grade DH steel with a hot-dipped galvanized finish. Designed for structural and heavy-duty fastening applications, this nut features a right-hand thread and measures 1.4375 inches (1-7/16 inches) across the flats with a height of 55/64 inches. The hot-dipped galvanizing provides corrosion resistance suited for outdoor, exposed, or high-moisture environments. Weighing approximately 0.28 pounds per unit, it is installed by ironworkers, structural steel contractors, millwrights, and maintenance mechanics on bolted connections requiring reliable thread engagement under load.

This hex nut is used in structural steel assembly, heavy equipment mounting, industrial framing, and infrastructure fastening where A563 Grade DH specifications are called out by the engineer of record or project specification. The UNC thread standard makes it compatible with standard 7/8-9 threaded rod, anchor bolts, and bolts of corresponding size. It is appropriate for both new construction and maintenance-and-repair work in commercial, industrial, and civil applications.

Key Features

• A563 Grade DH steel construction meets structural fastener requirements for heavy-duty bolted connections
• Hot-dipped galvanized finish provides corrosion protection for outdoor and high-moisture environments
• 7/8-9 UNC right-hand thread engages standard inch-series threaded fasteners and rods
• 1-7/16 inch (1.4375 inches) width across flats fits standard SAE and metric open-end and socket wrenches
• 55/64 inch height provides adequate thread engagement depth for structural load transfer

Compatibility

Designed for use with 7/8-9 UNC threaded bolts, rods, and studs conforming to standard inch-series thread specifications. Suitable as an OEM-style replacement or new-installation nut wherever A563 Grade DH hex nuts are specified.

Installation Notes

Installation should be performed by qualified ironworkers, structural mechanics, or maintenance personnel familiar with AISC and applicable structural fastening standards. Torque the nut using a calibrated torque wrench or impact tool appropriate to the bolt grade and joint specification — do not estimate final torque by feel alone on structural connections. Inspect threads for damage before installation and ensure mating bolt threads are free of debris. Always follow project specifications and applicable codes when used in structural or load-bearing assemblies.
