Value Collection CAI506205000 Carriage Bolt 5/8-11 5 in

Product Description

The VALUE COLLECTION CAI506205000 is a 5/8-11 carriage bolt with a 5-inch length under head, designed for general fastening applications across construction, mechanical, and fabrication work. The square neck under the domed head locks into a mating hole to prevent rotation during nut tightening, eliminating the need for a second wrench on the bolt side. Built from Grade 5 steel with a zinc plating finish, this bolt provides a solid combination of tensile strength and basic corrosion resistance for indoor and sheltered outdoor use. Thread standard is UNC (Unified National Coarse), measured at 5/8-11 thread size.

This carriage bolt is suited for wood-to-wood, wood-to-metal, and structural framing connections where a smooth, round head profile is required on the finished face. Common install scenarios include deck framing, equipment mounting, structural brackets, and general shop fabrication. The zinc-plated finish makes it appropriate for dry to moderately humid environments. It is sold individually and is a standard inch-system fastener compatible with 5/8-inch clearance holes and standard 5/8-11 hex nuts and washers.

Key Features

• Square neck under head prevents bolt rotation during installation without a backup tool
• Grade 5 steel construction provides medium-high tensile strength for structural fastening
• Zinc-plated finish offers basic corrosion protection for sheltered applications
• UNC 5/8-11 thread pattern for compatibility with standard inch-system hardware
• 5-inch length under head suits medium-depth structural connections
• Domed head profile leaves a clean, flush appearance on the exposed face

Compatibility

Designed for use with standard 5/8-11 UNC hex nuts and flat washers in inch-system fastening applications. Suitable for wood, metal, and composite substrates requiring a 5/8-inch clearance hole.

Installation Notes

Installation is typically performed by carpenters, ironworkers, or general tradespeople using a standard socket wrench or impact driver on the nut side. Insert the bolt through a pre-drilled 5/8-inch clearance hole so the square neck seats fully into the material before applying the nut. Apply torque to the nut only — driving the head directly may damage the dome profile or cause the neck to spin out. Follow applicable structural and building codes for fastener spacing and load requirements.
