Value Collection HCI30500375N-025BX Hex Head Bolt Grade A325

Product Description

The VALUE COLLECTION HCI30500375N-025BX is a 1/2-13 UNC hex head bolt manufactured from Grade A325 steel with a bright, uncoated finish. It measures 3-3/4 inches in length under the head and features partial threading, making it suited for structural and heavy-duty mechanical connections where a gripable unthreaded shank is required. Weighing approximately 0.32 pounds each, this fastener meets ASTM A325 standards and is appropriate for applications demanding high-strength bolt specifications. It is commonly installed by ironworkers, structural mechanics, and general contractors working to code-specified connection requirements.

This bolt is used in structural steel connections, heavy equipment assembly, and industrial fabrication applications where ASTM A325 high-strength fasteners are specified. The 1/2-13 UNC thread pattern is a widely used coarse-thread configuration compatible with standard hex nuts and washers. The uncoated finish is typical for interior structural applications or where field painting or coating will be applied after installation. Sold in multiples of 5, this fastener is stocked for job-site use across commercial and industrial construction projects.

Key Features

• Grade A325 steel construction meets ASTM A325 high-strength structural bolt standard
• 1/2-13 UNC coarse-thread pattern for compatibility with standard hardware
• 3-3/4 inch length under head suits medium-depth structural connections
• Partially threaded shank provides a bearing surface in the grip zone
• Bright, uncoated finish suitable for field coating or interior structural use
• Minimum order quantity of 5 units supports job-lot procurement

Compatibility

Designed as an ASTM A325-compliant structural hex head bolt for use with standard 1/2-13 UNC hex nuts and hardened washers in structural steel and heavy mechanical assemblies.

Installation Notes

Installation should be performed by qualified ironworkers or structural mechanics following applicable AISC and RCSC specifications for high-strength bolted connections. Always confirm proper nut grade and washer requirements before installing A325 bolts in structural applications. Torque or tension values must be sourced from the applicable project specifications or engineering documentation — do not assume standard torque without a defined connection design. Verify that the uncoated finish is acceptable for the exposure condition of the connection before installation.
