Value Collection HCI21002400G6 Hex Bolt 1-8 24in Grade 2

Product Description

The VALUE COLLECTION HCI21002400G6 is a heavy-duty hex head bolt designed for structural and general-purpose fastening applications. It features a 1-8 UNC thread size with a 24-inch length under the head, providing substantial grip length for thick material assemblies. Manufactured from Grade 2 steel with a hot-dipped galvanized finish, this bolt meets ASTM A307 standards for low-carbon steel fasteners. The partial threading configuration allows the shank to carry shear loads while the threaded section engages the nut or tapped hole. Licensed tradespeople and general contractors rely on this bolt where corrosion resistance and code-recognized fastener standards are required.

This bolt is suited for residential and light commercial construction, structural framing, equipment mounting, and infrastructure projects where galvanized fasteners are specified. Its 24-inch length makes it appropriate for through-bolting thick timber, laminated beams, or stacked structural members. It is also used in utility and agricultural applications where long fasteners and outdoor exposure are common. The hot-dipped galvanized coating provides durable protection in exterior and high-moisture environments.

Key Features

• 1-8 UNC thread size with 24-inch length under head for through-bolting thick assemblies
• Grade 2 steel construction meeting ASTM A307 fastener standard
• Hot-dipped galvanized finish for corrosion resistance in exterior and wet environments
• Partially threaded shank allows shear load transfer along the bolt body
• Inch measurement system with standard hex head for use with common wrenches and sockets

Compatibility

Designed as an OEM-style replacement or new-installation fastener for structural assemblies, timber framing, and equipment mounting applications requiring a 1-8 UNC partially threaded hex bolt to ASTM A307 specification.

Installation Notes

Installation is typically performed by carpenters, ironworkers, or general contractors using standard hex wrenches or impact sockets. Always use an appropriately rated nut and washer matched to the bolt grade and diameter. Consult applicable building codes and structural drawings for torque and assembly requirements before installation. Do not substitute a lower-grade fastener where ASTM A307 is specifically called out on engineering documents.
