Value Collection CAI506209000-015BX Carriage Bolt 5/8-11 9in

Product Description

The VALUE COLLECTION CAI506209000-015BX is a 5/8-11 carriage bolt with a 9-inch length under head, manufactured from Grade 5 steel with a zinc-plated finish. The square neck under the domed head resists rotation during installation, allowing the nut to be driven from one side without holding the bolt head. This fastener follows the Unified National Coarse (UNC) thread standard. It is suited for structural and mechanical assembly applications where a smooth, rounded head profile and corrosion-resistant finish are required. Licensed tradespeople and general contractors select this bolt for wood-to-wood and wood-to-metal connections in both light structural and equipment mounting tasks.

This carriage bolt is commonly used in residential and light commercial construction, equipment frames, dock and fence assemblies, and general mechanical fabrication. The zinc plating provides a baseline level of corrosion resistance appropriate for dry and intermittently wet interior environments. The 5/8-11 coarse thread engages standard hex nuts and washers readily available in trade supply. Typical applications include framing tie connections, joist hardware, and structural bracket fastening where a flush exterior head face is preferred.

Key Features

• 5/8-11 UNC thread for compatibility with standard coarse-thread nuts and hardware
• 9-inch length under head accommodates thick material stacks and through-bolt assemblies
• Square neck locks into wood or soft material to prevent spinning during nut tightening
• Grade 5 steel construction provides reliable tensile and proof-load strength for structural use
• Zinc-plated finish offers corrosion resistance in dry and light-moisture environments

Compatibility

Designed as a standard UNC 5/8-11 carriage bolt for use with matching coarse-thread hex nuts, flat washers, and lock washers in inch-measurement fastener assemblies.

Installation Notes

Installation is typically performed by carpenters, ironworkers, or general tradespeople using a standard wrench or impact driver on the nut side. Drive the square neck fully into the mating material before applying torque to the nut to ensure the head seats flush and the neck locks correctly. Always use an appropriately sized washer under the nut to distribute clamping load. De-energize any adjacent electrical systems and follow applicable building codes before performing structural fastening work.
