Value Collection CAI206204500-025BX Carriage Bolt 5/8-11

Product Description

The VALUE COLLECTION CAI206204500-025BX is a 5/8-11 UNC carriage bolt with a 4.5-inch length under the head, a square neck, and a zinc-plated Grade 2 steel construction. Carriage bolts are designed for through-bolting wood, metal, and other structural assemblies where a smooth, rounded head finish is required on the bearing surface. The square neck locks into the material to prevent rotation during tightening, eliminating the need for a wrench on the bolt end. This fastener meets ASTM A307 standards and is suited for general-purpose structural and mechanical fastening applications. Installed by contractors, maintenance technicians, and trades professionals across a wide range of construction and fabrication settings.

This carriage bolt is appropriate for residential and light commercial construction, wood framing connections, equipment mounting, and similar general fastening tasks where a flush, burr-free head profile is required on one side of the joint. The zinc plating provides a baseline level of corrosion resistance suitable for dry or mildly humid indoor environments. Fastener size is 5/8-11, meaning 5/8-inch nominal diameter with 11 threads per inch on the UNC thread standard. A standard hex nut and washer are typically used with this fastener on the threaded end.

Key Features

• 5/8-11 UNC thread for broad nut and hardware compatibility
• 4.5-inch length under head suits medium-depth through-bolt applications
• Square neck resists rotation during installation without a second wrench
• Grade 2 steel meets ASTM A307 tensile requirements for general structural use
• Zinc plating provides corrosion resistance in dry and low-humidity environments
• Smooth domed head delivers a clean bearing surface on the visible face

Compatibility

Designed as a general-purpose inch-series carriage bolt compatible with standard 5/8-11 UNC hex nuts, coupling nuts, and washers used in wood-to-wood and wood-to-metal fastening assemblies.

Installation Notes

Installation is typically performed by carpenters, ironworkers, or general maintenance trades. Drill a clean through-hole sized to the bolt nominal diameter so the square neck seats flush and locks without splitting the material. Apply torque to the nut end only using a standard wrench or socket; do not attempt to drive or torque the domed head. Follow applicable building codes and engineer specifications for required torque values and connection design in structural applications.
