Value Collection HCI30870575NG-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI30870575NG-005BX is a 7/8-9 UNC hex head bolt designed for structural and heavy-duty fastening applications. Manufactured from Grade A325 steel with a hot-dipped galvanized finish, it provides corrosion resistance in demanding environments. The bolt measures 5-3/4 inches in length under the head and features partial threading, making it well-suited for through-bolt applications where the shank must bear shear loads. It conforms to ASTM A325 standards and is appropriate for structural steel connections and other load-bearing assemblies. Licensed tradespeople and structural contractors select this fastener for code-compliant connections.

This bolt is used in structural steel erection, heavy equipment mounting, and industrial framing where ASTM A325 compliance is required. The hot-dipped galvanized finish extends service life in outdoor, high-humidity, or corrosive environments. Ironworkers, millwrights, and general contractors commonly install this fastener in both new construction and retrofit projects that specify high-strength structural bolts.

Key Features

• 7/8-9 UNC thread size with partial threading for shear-load-bearing shank sections
• Grade A325 structural steel construction, conforming to ASTM A325
• Hot-dipped galvanized finish for corrosion resistance in outdoor and wet environments
• 5-3/4 inches length under head for deep through-bolt applications
• Inch measurement system; compatible with standard imperial tooling

Compatibility

Designed as an ASTM A325-compliant structural hex head bolt for use in applications specifying 7/8-9 UNC partially threaded fasteners with a hot-dipped galvanized finish.

Installation Notes

Installation should be performed by qualified ironworkers, millwrights, or structural contractors following applicable building codes and AISC/RCSC specifications for structural bolt assemblies. Shut down and de-energize any adjacent systems before working in close proximity to electrical components. Use calibrated torque wrenches or the turn-of-nut method as required by project specifications. Do not re-use structural bolts that have been fully tensioned unless permitted by the governing specification.
