Value Collection HCI31000700N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31000700N-005BX is a heavy hex head bolt designed for structural and industrial fastening applications. It features a 1-8 UNC thread size with a 7-inch length under the head and is partially threaded along the shank. Manufactured from steel to ASTM A325 specifications, this bolt delivers the tensile strength required for structural steel connections, heavy equipment assembly, and load-bearing mechanical joints. The bright uncoated finish is standard for A325-grade structural bolts intended for use in controlled environments or where coating will be applied on-site. Weighing approximately 1 pound, it ships in a single-piece package.

This bolt is suited for structural steel erection, heavy fabrication, and general industrial assembly where ASTM A325 compliance is required. A325 bolts are commonly specified in steel-to-steel connections on commercial and industrial construction projects, including beam-to-column joints, bridge components, and equipment frames. The 1-8 UNC thread standard is a coarse-thread profile widely used across structural and mechanical fastening in North American construction.

Key Features

• ASTM A325 structural bolt specification for high-strength fastening
• 1-8 UNC coarse thread for broad tooling and nut compatibility
• 7-inch length under head suits thick stack-ups and multi-layer connections
• Partial threading preserves shank bearing area in the grip zone
• Bright uncoated finish meets standard structural bolt appearance requirements
• Inch measurement system compatible with standard structural hardware

Compatibility

Designed as an ASTM A325-compliant structural hex head bolt for use with standard 1-8 UNC heavy hex nuts and hardened washers in structural steel assemblies per applicable construction specifications.

Installation Notes

Installation of A325 structural bolts should be performed by qualified ironworkers or structural mechanics following AISC and RCSC specifications for structural joints. Bolts must be installed with compatible A325 heavy hex nuts and hardened washers. Snug-tighten before applying final torque or turn-of-nut method as specified in the connection design. Do not impact-drive A325 bolts without verifying that the installation method meets the project specification requirements.
