Value Collection HCI31000500NG-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31000500NG-005BX is a 1-8 UNC hex head bolt designed for structural and heavy-duty mechanical fastening applications. Manufactured from A325 grade steel with a hot-dipped galvanized finish, this bolt measures 5 inches in length under the head and features partial threading. The A325 material grade meets ASTM A325 standards, making it suitable for structural steel connections where high-strength fasteners are required. Weighing approximately 1.848 pounds, this bolt is sized for applications demanding reliable clamping force and corrosion resistance from the galvanized coating.

This hex head bolt is used in structural steel construction, heavy equipment assembly, and industrial maintenance applications. The 1-inch diameter with UNC thread form and partial threading is standard in structural bolted connections where the unthreaded shank provides shear strength across the joint. It is typically installed by ironworkers, millwrights, and maintenance mechanics working on steel frame structures, machinery bases, and similar load-bearing assemblies requiring ASTM A325 compliance.

Key Features

• A325 grade steel construction meets ASTM A325 structural bolt standard
• Hot-dipped galvanized finish provides corrosion resistance for exterior and exposed applications
• Partially threaded shank delivers shear strength across bolted joint interfaces
• 1-8 UNC thread form for compatibility with standard heavy-duty structural hardware
• 5-inch length under head suits thick structural member connections

Compatibility

Designed as an OEM-style replacement or new-installation fastener for structural and industrial assemblies requiring 1-8 UNC hex head bolts conforming to ASTM A325 specifications.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or mechanics following applicable structural codes, including AISC and RCSC specification requirements for high-strength bolted connections. Verify mating nut and washer specifications match the A325 bolt grade before assembly. Power down or de-energize any associated equipment before working in the fastener area. Do not substitute impact-only installation without confirming the connection design allows snug-tight or pre-tensioned methods as required by the structural drawings.
