Value Collection 14112CGNFG Carriage Bolt 1/4-20 7in Square Neck

Product Description

The VALUE COLLECTION 14112CGNFG is a partially threaded carriage bolt designed for through-bolting applications in wood, metal, and structural assemblies. Manufactured from 1006/1050 grade steel with a galvanized zinc finish, it provides corrosion resistance in both indoor and outdoor environments. The 1/4-20 UNC thread and square neck beneath the rounded head prevent rotation during tightening without requiring a wrench on the bolt itself. At 7 inches in length under head, this fastener suits deeper assemblies where standard short bolts fall short. It conforms to ASME B18.5 standards for carriage bolt geometry and dimensional tolerances.

This carriage bolt is suited for general construction, wood framing connections, playground equipment, deck hardware, and light structural fabrication. The square neck seats into pre-drilled or punched square holes in wood substrates, locking the bolt in place as the nut is driven from the opposite side. Tradespeople, contractors, and maintenance professionals working in corrosive or exterior environments benefit from the galvanized coating, which resists rust and surface oxidation over time.

Key Features

• 1/4-20 UNC thread for compatibility with standard imperial nuts and hardware
• Square neck design prevents bolt rotation during installation without additional tooling on the head
• Galvanized zinc finish provides corrosion resistance for exterior and wet environment use
• 7-inch length under head accommodates deeper through-bolt assemblies
• Partially threaded shank preserves shear strength along the unthreaded body
• Meets ASME B18.5 dimensional standards for carriage bolts

Compatibility

Designed as a standard imperial carriage bolt for use with 1/4-20 UNC hex nuts and washers in wood-to-wood and wood-to-metal fastening applications.

Installation Notes

Installation is performed by driving the square neck into a matching square-punched or round-drilled hole in a wood substrate so the head seats flush, then threading a washer and nut from the opposite side. Power down any adjacent electrical systems and follow applicable structural fastening guidelines before beginning work. Do not over-torque the nut, as this can strip the wood fibers surrounding the square neck and allow bolt rotation. A standard wrench or socket is sufficient for nut tightening; no tool is needed on the bolt head.
