Value Collection HCI31120300N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31120300N-005BX is a fully threaded hex head bolt designed for structural and heavy-duty mechanical fastening applications. Manufactured from Grade A325 steel in an uncoated bright finish, this bolt meets ASTM A325 standards for structural bolt assemblies. The thread specification is 1-1/8-7 UNC, with a 3-inch length measured under the head. Fully threaded from head to tip, it provides maximum thread engagement across the full shaft length. At approximately 1 pound per unit, this bolt is suited for high-load connections where a recognized structural fastening standard is required.

This bolt is used in structural steel construction, heavy equipment fabrication, bridge work, and industrial machinery assembly. ASTM A325 bolts are a standard specification in steel-to-steel connections governed by AISC and RCSC guidelines. Licensed contractors, structural ironworkers, millwrights, and mechanical tradespeople typically install these fasteners in applications requiring a verified material grade and traceable fastening standard. The fully threaded configuration makes it appropriate where thread engagement is needed along the full grip length.

Key Features

• Thread size 1-1/8-7 UNC for compatibility with standard structural hardware
• 3-inch length under head provides substantial grip range for thick material stacks
• Fully threaded shaft maximizes thread engagement along the entire bolt length
• Grade A325 steel meets ASTM A325 structural bolt requirements
• Uncoated bright finish — no coating interference on faying surfaces
• Inch measurement system; length type is length under head

Compatibility

Designed as a standard ASTM A325 structural hex head bolt for use with compatible 1-1/8-inch heavy hex nuts and structural washers in inch-series fastener assemblies.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified tradespeople in accordance with RCSC Specification for Structural Joints and applicable building codes. Always de-energize or isolate connected equipment before working on bolted assemblies under load. Use calibrated torque wrenches or direct-tension indicators where specified by the engineer of record. Do not substitute Grade A325 hardware with lower-grade fasteners in structural connections.
