Value Collection HCI30870450N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI30870450N-005BX is a heavy-duty hex head bolt designed for structural and industrial fastening applications. This bolt features a 7/8-9 thread size with Unified National Coarse (UNC) thread form and measures 4-1/2 inches in length under the head. Manufactured from steel to ASTM A325 material grade requirements, it delivers the tensile strength needed for high-load structural connections. The partially threaded shank and bright uncoated finish are standard for structural bolt installations. Licensed contractors, ironworkers, and maintenance mechanics rely on this fastener in steel-to-steel connections where code-specified bolt grades are required.

This bolt is suited for structural steel framing, heavy equipment assembly, and other load-bearing connections where ASTM A325 grade fasteners are specified by engineering drawings or applicable construction codes. The 7/8-9 UNC thread pattern is a commonly specified size in structural applications governed by AISC, RCSC, and related standards. Its partially threaded configuration keeps the unthreaded shank in the bearing zone of the connection, which is the standard practice in most bolted structural joints.

Key Features

• ASTM A325 material grade meets structural bolt strength requirements for code-governed connections
• 7/8-9 UNC thread for compatibility with standard structural nuts and washers
• 4-1/2 inch length under head accommodates typical multi-ply structural steel stack-ups
• Partially threaded shank positions the unthreaded body in the shear plane of the joint
• Bright uncoated finish — field verify corrosion protection requirements before installation

Compatibility

Designed as an OEM-style replacement or direct-use structural fastener for applications requiring ASTM A325 hex head bolts in 7/8-9 UNC thread size.

Installation Notes

Installation of structural bolts should be performed by qualified ironworkers or licensed contractors following RCSC Specification for Structural Joints and applicable project specifications. Power down or de-energize any electrical systems in the work area before beginning structural work per applicable safety codes. Use calibrated torque wrenches or turn-of-nut methods as specified by the engineer of record. Do not reuse structural bolts that have been fully tensioned unless explicitly permitted by the applicable standard.
