Value Collection HCI31120500N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31120500N-005BX is a heavy-duty hex head bolt designed for structural fastening applications requiring high strength and dimensional precision. This bolt features a 1-1/8-7 UNC thread form with a 5-inch length under head, partially threaded shank, and a bright uncoated finish on low-alloy steel. It meets ASTM A325 structural bolt standards, making it appropriate for steel-to-steel connections in construction and industrial assemblies. Licensed contractors and ironworkers rely on A325 hardware for bolted structural joints governed by AISC and RCSC specifications.

This bolt is suited for structural steel connections in commercial and industrial construction, including beam-to-column connections, base plate installations, and heavy equipment mounting. The 1-1/8-inch major diameter and partially threaded shank provide bearing surface in the grip zone, which is the correct configuration for most structural shear connections. The uncoated finish is intended for use where surface treatment will be applied on-site or where coating is not required by the project specification.

Key Features

• 1-1/8-7 UNC thread form for positive engagement in structural steel applications
• 5-inch length under head with partially threaded shank for shear-bearing connections
• Grade A325 steel meets ASTM A325 structural bolt standard
• Bright uncoated finish for compatibility with field-applied coatings or bare steel connections
• Inch measurement system for use with standard imperial hardware and tooling

Compatibility

Designed as an ASTM A325 structural hex head bolt for use in bolted steel connections conforming to RCSC and AISC structural steel connection specifications requiring 1-1/8-7 UNC partially threaded fasteners.

Installation Notes

Installation should be performed by qualified ironworkers or structural contractors following RCSC Specification for Structural Joints requirements. Power down or de-energize any adjacent electrical systems before working in the installation area. Use calibrated torque wrenches or tension-control tooling as specified by the connection design to achieve required pretension. Do not reuse A325 bolts that have been fully tensioned, as the standard does not permit reuse in pretensioned or slip-critical joints.
