Value Collection HCI30750425N-010BX Hex Head Bolt 3/8-16

Product Description

The VALUE COLLECTION HCI30750425N-010BX is a hex head bolt designed for structural and general mechanical fastening applications. It features a 3/8-16 UNC thread and measures 4-1/4 inches in length under the head. Manufactured from steel to ASTM A325 specifications, this bolt delivers the high-strength performance required in structural steel connections and heavy-duty assembly work. The partially threaded shank provides a bearing surface in the grip area, which is critical for shear-loaded joints. The bright, uncoated finish is standard for indoor or protected installations where corrosion exposure is minimal.

This bolt is suited for structural steel fabrication, heavy equipment assembly, and industrial maintenance applications where ASTM A325 grade fasteners are specified. It is commonly installed by ironworkers, millwrights, and maintenance mechanics working to structural or mechanical specifications that call out high-strength inch-series fasteners. The 3/8-16 UNC thread is one of the most common inch-series thread forms, making this bolt widely applicable across steel construction and machine assembly contexts.

Key Features

• ASTM A325 structural bolt standard for high-strength fastening requirements
• 3/8-16 UNC thread for compatibility with standard inch-series nuts and tapped holes
• 4-1/4 inch length measured under the head for precise grip-length selection
• Partially threaded shank provides a full bearing surface in shear-critical joints
• Bright uncoated finish suitable for dry or protected installation environments
• Steel construction meets the mechanical property requirements of ASTM A325

Compatibility

Designed as an OEM-style replacement or direct-use fastener for structural and mechanical assemblies specifying 3/8-16 UNC hex head bolts meeting ASTM A325 requirements.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or mechanics following the applicable provisions of the AISC or RCSC specification for structural joints. Fastener installation torque should be determined from the project engineering specifications or the RCSC Specification for Structural Joints Using High-Strength Bolts. Always use a calibrated torque wrench or an approved snug-tight or pretensioned installation method as required by the project. Do not reuse A325 bolts in pretensioned applications unless specifically permitted by the engineer of record.
