Value Collection HCI30750450N-010BX Hex Head Bolt 3/4-10

Product Description

The VALUE COLLECTION HCI30750450N-010BX is a 3/4-10 UNC hex head bolt manufactured from Grade A325 steel with a bright uncoated finish. It measures 4.5 inches in length under the head and features partial threading, making it well suited for structural and heavy-duty mechanical connections where a bearing-length shank is required. The bolt conforms to ASTM A325 standards, a common requirement in steel construction and high-strength fastener applications. Weighing approximately 1 pound per unit, it is sold individually. Licensed tradespeople including ironworkers, structural mechanics, and commercial contractors rely on this fastener type for bolted steel connections governed by recognized load standards.

This bolt is used in structural steel assemblies, heavy equipment fabrication, and commercial construction applications where high-strength fasteners meeting ASTM A325 requirements are specified. Partially threaded bolts of this type are commonly called out in connection designs that require a smooth shank in the grip zone to resist shear loads. Typical install scenarios include beam-to-column connections, base plate anchoring, and heavy mechanical equipment mounting where torque and clamp load values are defined by engineering specifications or governing codes.

Key Features

• Meets ASTM A325 high-strength structural bolt standard
• 3/4-10 UNC thread size for compatibility with standard heavy-duty hardware
• Partial threading provides a smooth shank in the grip zone to handle shear loads
• Bright uncoated finish — suitable for painted or coated assemblies after installation
• 4.5 inches length under head for use in thicker connection stacks
• Sold individually with no minimum order quantity above one unit

Compatibility

Designed as an ASTM A325-compliant hex head bolt for structural steel and heavy mechanical fastening applications requiring a 3/4-10 UNC thread pattern and partial threading configuration.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural mechanics following the applicable provisions of AISC or project-specific engineering drawings. Bolt torque, pretension, and inspection requirements are governed by the connection design and must not be assumed from generic values. Always verify nut and washer specifications match the bolt grade before assembly. Do not impact-drive or field-modify this fastener.
