Value Collection 5072CGNFG Carriage Bolt 1/2-13 4.5 in

Product Description

The VALUE COLLECTION 5072CGNFG is a fully threaded carriage bolt designed for structural fastening applications where a smooth, rounded head and a square neck are required to prevent rotation during installation. Manufactured from Grade 1006-1050 steel with a galvanized zinc-plated finish, this bolt provides corrosion resistance suitable for general-purpose indoor and outdoor assemblies. The 1/2-13 UNC thread runs the full 4.5 inches of the shank length under the head, conforming to ASME B18.5 dimensional standards. It is installed by plumbers, electricians, contractors, and maintenance technicians working on equipment mounting, structural connections, and utility framing.

This carriage bolt is suited for residential and light commercial construction, equipment mounting, wood-to-metal connections, and utility support framing. The square neck locks into pre-bored square holes or bites into wood substrate to resist turning, allowing the nut to be tightened from one side without holding the bolt head. It is commonly used in applications where flush-head fastening is required and access to both sides of the workpiece may be limited.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard nuts and hardware
• Fully threaded 4.5-inch shank length under head for maximum thread engagement flexibility
• Square neck prevents rotation during tightening without tools on the bolt head
• Galvanized zinc-plated finish provides corrosion resistance for general-purpose use
• Meets ASME B18.5 dimensional and fastener standards
• Grade 1006-1050 steel construction for reliable strength in standard load applications

Compatibility

Designed as a standard inch-series carriage bolt for use with 1/2-13 UNC nuts and washers in general structural, framing, and equipment-mounting assemblies.

Installation Notes

Installation is performed by the appropriate trade or contractor depending on the application. Power down or de-energize any adjacent electrical equipment before working in proximity to live panels or conductors. Insert the bolt through a pre-drilled hole sized to allow the square neck to seat flush and resist rotation, then apply a washer and nut on the threaded end and tighten to the torque specification required by the assembly drawing or applicable code. Refer to ASME or project-specific fastener requirements when used in structural or load-bearing connections.
