Value Collection 781136PS Carriage Bolt 1/2-13 10 in Square Neck

Product Description

The VALUE COLLECTION 781136PS is a 1/2-13 carriage bolt with a 10-inch length under head, manufactured from 18-8 stainless steel with a bright uncoated finish. The square neck design locks the bolt in place as the nut is tightened, preventing rotation without requiring a wrench on the bolt head. This fastener follows Unified National Coarse (UNC) thread standards, making it compatible with standard 1/2-13 hardware. It is a reliable choice for structural, marine, and outdoor applications where corrosion resistance is a priority. Maintenance technicians, contractors, and tradespeople working with wood framing, docks, or equipment assemblies commonly specify this bolt type.

This carriage bolt is suited for through-fastening applications in wood, composite, and light structural materials. The 10-inch length under head accommodates thick lumber, stacked panels, or assemblies requiring extended reach. The 18-8 stainless steel construction makes it appropriate for wet, coastal, or corrosive environments where carbon steel fasteners would degrade. It is sold individually and fits standard applications requiring a 1/2-13 hex nut or corresponding hardware.

Key Features

• 1/2-13 UNC thread for compatibility with standard 1/2-13 nuts and hardware
• 10-inch length under head for through-fastening thick assemblies
• Square neck prevents bolt rotation during installation without additional tooling
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Bright uncoated finish — no plating to flake, chip, or interfere with fit
• Inch measurement system; sold as a single-unit package

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, washers, and corresponding hardware in inch-system fastener assemblies.

Installation Notes

Installation typically requires drilling a clearance hole sized to the bolt shank diameter through the mating materials. The square neck seats into the material to prevent spinning while the nut is tightened from the opposite side using a standard wrench or socket. Ensure the bolt is fully seated before applying final torque to the nut. Follow applicable building codes and structural specifications for load-bearing or safety-critical connections.
