Value Collection HCI31000250NG-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31000250NG-005BX is a fully threaded hex head bolt designed for heavy structural and mechanical fastening applications. It carries a Grade A325 material designation and meets ASTM A325 standards, making it suitable for high-strength structural connections. The bolt has a 1-8 thread size with UNC thread form and a length under head of 2.5 inches. A hot-dipped galvanized finish provides corrosion resistance in outdoor and high-moisture environments. Installers in structural steel, construction, and industrial maintenance work will encounter this fastener in steel-to-steel and bracket connections where torqued bolted joints are specified.

This bolt is used in structural steel assembly, equipment mounting, and heavy fabrication work where ASTM A325 high-strength fasteners are required by specification or code. The fully threaded shank allows engagement across the full grip length, which is common in connections with variable stack thickness or where the threaded portion must extend through the full joint. It is appropriate for both new construction and retrofit applications in commercial and industrial settings where galvanized hardware is called out for corrosion resistance.

Key Features

• Grade A325 high-strength steel meets ASTM A325 fastener standard
• Fully threaded shank for maximum thread engagement across full grip length
• Hot-dipped galvanized finish for corrosion resistance in outdoor and wet environments
• 1-8 UNC thread form with 2.5 inch length under head
• Hex head drive style compatible with standard wrenches and impact tools

Compatibility

Designed as an ASTM A325-compliant hex head bolt for use in structural steel and heavy mechanical fastening applications where high-strength inch-series UNC fasteners are specified.

Installation Notes

Installation should be performed by qualified tradespeople in accordance with applicable structural codes, including AISC and RCSC specifications for high-strength bolted connections. Torque values must be determined from the applicable project specification or engineering documentation — do not assume a torque value from this listing. Use appropriate wrenches, torque wrenches, or tension-control tools as required by the connection type. Inspect the galvanized coating for damage before installation and replace any bolt with coating defects in corrosive service environments.
