Value Collection HCI30500350N-025BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI30500350N-025BX is a 1/2-13 UNC hex head bolt rated to ASTM A325 structural steel standards. It measures 3.5 inches in length under the head and is partially threaded, leaving a smooth shank section near the head for shear-load applications. Manufactured from uncoated steel with a bright finish, this fastener is suited for high-strength structural connections where a recognized material grade specification is required. Ironworkers, structural mechanics, and commercial contractors install this type of fastener in steel-to-steel connections on framing, equipment bases, and structural assemblies.

This bolt fits standard 1/2-13 UNC threaded applications requiring ASTM A325 compliance. It is commonly used in structural steel construction, including beam connections, column splices, and base plate installations. The uncoated finish is appropriate for interior structural applications or where a field-applied coating will be added after installation. Minimum order quantity is 5 pieces.

Key Features

• ASTM A325 rated for high-strength structural steel connections
• 1/2-13 UNC thread size for compatibility with standard hex nuts and washers
• Partially threaded shank provides a smooth bearing surface for shear loads
• Uncoated bright finish suitable for field coating or interior structural use
• 3.5-inch length under head accommodates multi-ply structural steel connections

Compatibility

Designed for use in standard 1/2-13 UNC threaded structural applications requiring ASTM A325 high-strength fasteners. Intended for use with matching heavy hex nuts and hardened washers per applicable structural specifications.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural mechanics following AISC and RCSC specifications for high-strength bolted connections. Use calibrated torque wrenches or tension-control tooling appropriate to the bolt diameter and specified pretension requirements. Do not field-modify thread engagement or shank length. Inspect mating surfaces for burrs or debris before assembly to ensure proper bearing and clamping force.
