Value Collection CAI506204500-025BX Carriage Bolt 5/8-11

Product Description

The VALUE COLLECTION CAI506204500-025BX is a 5/8-11 UNC carriage bolt with a 4-1/2-inch length under head and a square neck profile. It is manufactured from Grade 5 steel with a zinc-plated finish that provides baseline corrosion resistance for general fastening applications. The square neck seats under the bearing surface to resist rotation during tightening, eliminating the need for a wrench on the bolt head. This fastener is a standard inch-system component suited for structural assembly, equipment mounting, and general mechanical work across construction, HVAC equipment installation, and related trades.

This carriage bolt is used in applications where a smooth, domed head is required on the exposed face of the assembly and the fastener must be drawn tight from the nut side only. It is appropriate for wood-to-wood, wood-to-metal, and light structural metal connections. The zinc plating makes it suitable for indoor and dry-to-mildly-humid environments. Typical users include HVAC installers securing equipment pads and frames, general contractors, and maintenance technicians working with standard inch-thread hardware.

Key Features

• 5/8-11 UNC thread for compatibility with standard inch-series nuts and hardware
• 4-1/2-inch length under head accommodates moderate material stack thickness
• Square neck profile locks into workpiece during installation to prevent rotation
• Grade 5 steel construction provides enhanced tensile strength over Grade 2
• Zinc-plated finish offers corrosion resistance for indoor and dry-environment use

Compatibility

Designed as a standard inch-system replacement or stock carriage bolt for use with 5/8-11 UNC hex nuts and washers in general structural and mechanical fastening applications.

Installation Notes

Installation is typically performed by mechanics, HVAC technicians, or general tradespeople using standard hand tools. Insert the bolt through the pre-drilled hole so the square neck seats firmly in the material before threading the nut. Tighten from the nut side only using an appropriately sized wrench or socket. Do not apply heat or weld adjacent to the zinc-plated finish, as this produces hazardous fumes.
