Value Collection CAI206209000 Carriage Bolt 5/8-11 9 in

Product Description

The VALUE COLLECTION CAI206209000 is a 5/8-11 UNC carriage bolt with a 9-inch length under head and a square neck, manufactured from Grade 2 steel with a zinc-plated finish. Carriage bolts use a smooth, domed head and a square neck that bites into the material being fastened, preventing the fastener from spinning during installation. This bolt meets ASTM A307 standards, making it suitable for general-purpose structural and mechanical fastening applications. Weighing 0.73 pounds, it is a solid, full-size fastener intended for use by tradespeople, contractors, and maintenance professionals working with wood, metal, or composite assemblies.

This carriage bolt is used in a wide range of residential and light commercial construction and maintenance scenarios, including wood-to-wood connections, fence and gate assemblies, deck framing, equipment mounting, and utility structures. The 5/8-11 thread size is a common heavy-duty designation found in structural framing, dock construction, and trailer or equipment fabrication. The zinc-plated finish provides a baseline level of corrosion resistance suitable for dry or occasionally damp indoor environments.

Installation Notes

Installation is typically performed by carpenters, ironworkers, or general contractors using a standard wrench or socket set to drive the mating nut. Drill a clean, properly sized hole to allow the square neck to seat flush and grip the material without spinning. Avoid over-torquing, which can strip the Grade 2 threads or crush softer base materials such as wood. Follow applicable building codes and structural specifications for fastener grade and spacing requirements.
