Value Collection HCI30750200N-015BX Hex Head Bolt 3/4-10

Product Description

The VALUE COLLECTION HCI30750200N-015BX is a hex head bolt designed for structural and mechanical fastening applications. It features a 3/4-10 UNC thread and a 2-inch length under head, with partial threading along the shank. Manufactured from uncoated steel to the ASTM A325 material grade standard, this bolt is suited for high-strength structural connections. It is installed by ironworkers, millwrights, and general contractors in steel-to-steel assemblies where torque-controlled or turn-of-nut installation methods are specified. The uncoated bright finish is appropriate for interior or protected environments where surface treatment is applied separately.

This bolt is commonly used in structural steel framing, machinery mounting, and heavy mechanical assemblies requiring Grade A325 fasteners. ASTM A325 specifies minimum tensile strength requirements that make these bolts appropriate for structural bolt group applications as defined in AISC and RCSC specifications. The 3/4-10 UNC thread is a standard inch-series coarse thread widely compatible with standard hex nuts and washers in that thread family.

Key Features

• 3/4-10 UNC coarse thread for broad compatibility with standard hardware
• 2-inch length under head for measured grip range in structural connections
• Partially threaded shank allows load transfer through the unthreaded body in bearing connections
• ASTM A325 material grade meets structural bolt strength requirements
• Uncoated bright finish suitable for field-coated or protected installations
• Inch system of measurement for use with standard SAE tooling and hardware

Compatibility

Designed as an OEM-style replacement or standard-stock hex head bolt for structural and mechanical fastening applications requiring ASTM A325 Grade hardware in 3/4-10 UNC thread size.

Installation Notes

Installation should be performed by qualified ironworkers, millwrights, or mechanical contractors in accordance with RCSC Specification for Structural Joints Using High-Strength Bolts. Always de-energize and lock out equipment before fastener installation on mechanical assemblies. Use calibrated torque wrenches or follow the turn-of-nut method as specified by the project engineer. Do not impact-drive ASTM A325 bolts without verifying the installation method meets the applicable specification.
