Value Collection CAI204302500-050BX Carriage Bolt 7/16-14

Product Description

The VALUE COLLECTION CAI204302500-050BX is a 7/16-14 UNC carriage bolt with a 2-1/2 inch length under the head and a square neck drive style. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener is built for general-purpose structural and mechanical assemblies where a smooth, rounded head and self-locking square neck are required. The zinc coating provides basic corrosion resistance suitable for indoor and light outdoor applications. This bolt meets ASTM A307 standards, making it appropriate for low-carbon steel fastener applications across construction, fabrication, and maintenance work.

This carriage bolt is suited for wood-to-wood and wood-to-metal connections in residential construction, light commercial framing, equipment mounting, and general fabrication tasks. The square neck seats into a pre-drilled square or round hole in wood, preventing rotation during nut tightening without requiring a wrench on the bolt head. Contractors, carpenters, ironworkers, and maintenance technicians regularly install this type of fastener in decking, fencing, structural frames, and machinery guards.

Key Features

• 7/16-14 UNC thread size for compatibility with standard inch-series nuts and tapped holes
• 2-1/2 inch length under head provides adequate grip length for common structural assemblies
• Square neck design locks into wood or punched material to prevent bolt rotation during installation
• Grade 2 steel construction meets ASTM A307 requirements for general low-carbon fastener applications
• Zinc-plated finish offers basic corrosion resistance for indoor and protected outdoor use

Compatibility

Designed as a standard inch-series carriage bolt for use with 7/16-14 UNC hex nuts and washers in wood, light-gauge metal, and structural assemblies requiring ASTM A307 compliant fasteners.

Installation Notes

Installation is typically performed by carpenters, structural ironworkers, or general maintenance technicians using standard hand or power tools. Insert the bolt through a pre-drilled hole sized to allow the square neck to seat flush and resist rotation, then thread on a washer and nut from the opposite side. Tighten the nut with a wrench while the bolt head remains stationary. Follow applicable building codes and fastener schedules for structural connections.
