Value Collection HCI31120350N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31120350N-005BX is a fully threaded hex head bolt designed for structural and heavy-duty fastening applications. It features a 1-1/8-7 UNC thread and measures 3.5 inches in length under the head. Manufactured from steel to ASTM A325 specifications, this bolt delivers the high-strength performance required in structural steel connections and load-bearing assemblies. The bright, uncoated finish is standard for A325 structural fasteners. This bolt is sold individually and is suited for use by ironworkers, structural contractors, and industrial maintenance technicians working to AISC or similar structural standards.

This bolt is appropriate for structural steel connections, heavy equipment assembly, and industrial fabrication where ASTM A325 compliance is required. The fully threaded configuration provides consistent thread engagement across the full grip range, making it a practical choice in applications where standard partial-thread bolts may not provide sufficient engagement depth. It is commonly installed in steel-to-steel connections in both commercial construction and industrial plant settings.

Key Features

• ASTM A325 compliant — meets structural bolt strength requirements
• Fully threaded for maximum thread engagement along the entire shank
• 1-1/8-7 UNC thread size for compatibility with standard heavy-duty nuts and hardware
• 3.5 inches length under head — suitable for moderate grip-length structural connections
• Bright uncoated finish — no surface coating to interfere with slip-critical joint testing
• Steel construction provides the hardness and tensile strength specified by ASTM A325

Compatibility

Designed as an ASTM A325 structural hex head bolt for use with compatible 1-1/8-7 UNC heavy hex nuts and structural washers in conformance with AISC and RCSC structural bolt installation standards.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural steel erectors following RCSC Specification for Structural Joints guidelines. Fully tighten using the turn-of-nut, calibrated wrench, direct tension indicator, or twist-off method as specified by the engineer of record. De-energize or isolate any adjacent energized systems before working in electrical proximity. Do not reuse A325 bolts that have been fully pretensioned, as fatigue and yield characteristics may be compromised.
