Value Collection HCI31000300N-005BX Hex Head Bolt Grade A325

Product Description

The VALUE COLLECTION HCI31000300N-005BX is a heavy-duty hex head bolt designed for structural and mechanical fastening applications. Manufactured from steel to ASTM A325 material grade standards, this bolt features a 1-8 UNC thread size and measures 3 inches in length with a partially threaded shank. The partial thread design provides additional shank strength in high-load bearing joints. This bolt is appropriate for use by millwrights, ironworkers, structural steel erectors, and general contractors working on steel-to-steel connections where ASTM A325 compliance is required.

This hex head bolt is suited for structural steel construction, machinery assembly, and heavy industrial fastening applications. The partially threaded configuration is commonly specified in bolted moment connections and shear tab assemblies where the unthreaded shank spans the interface between joined members. It is appropriate for both new construction and retrofit structural work where ASTM A325-rated fasteners are called out on engineering drawings.

Key Features

• ASTM A325 material grade meets structural bolt standards for high-strength steel fastening
• 1-8 UNC thread size for compatibility with standard heavy-hex nuts and structural hole tolerances
• 3-inch length with partially threaded shank for shear-critical load paths
• Steel construction provides high tensile and proof load capacity
• Hex head drive style compatible with standard impact wrenches and torque tools

Compatibility

Designed as a structural replacement or direct-use hex head bolt for applications specifying ASTM A325 Grade, 1-8 UNC thread, 3-inch length, partially threaded fasteners.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural trades following AISC and RCSC bolt installation specifications. Fasteners must be installed with the appropriate heavy-hex nut and hardened washer where required by the connection design. Power down and de-energize any associated electrical or mechanical systems before working in the connection zone. Do not reuse ASTM A325 bolts that have been fully tensioned, as they may not be suitable for reuse per RCSC guidelines.
