Value Collection CAI506202500-025BX Carriage Bolt 5/8-11

Product Description

The VALUE COLLECTION CAI506202500-025BX is a 5/8-11 UNC carriage bolt with a 2-1/2 inch length under head and a square neck design. It is manufactured from Grade 5 steel with a zinc plating finish that provides corrosion resistance for general fastening applications. The square neck locks into wood or composite material to prevent rotation during installation, eliminating the need for a second wrench on the bolt head. Installers and maintenance professionals in construction, mechanical, and light industrial trades commonly use this fastener for structural connections and equipment mounting.

This carriage bolt is suited for through-bolting applications in wood framing, metal brackets, and structural assemblies where a flush, round head profile is required. The 5/8-11 UNC thread is a standard coarse-thread specification widely used in residential and commercial construction as well as general mechanical maintenance. The zinc plating makes it appropriate for indoor or sheltered outdoor environments where mild corrosion resistance is needed.

Key Features

• 5/8-11 UNC coarse-thread specification for broad hardware compatibility
• 2-1/2 inch length under head suits standard through-bolting applications
• Square neck design prevents bolt rotation during tightening without a backup tool
• Grade 5 steel provides solid tensile and shear strength for structural fastening
• Zinc-plated finish adds corrosion resistance for sheltered environments

Compatibility

Designed as a standard UNC carriage bolt for use in wood, composite, and metal through-bolt applications requiring a 5/8-11 coarse-thread fastener with a 2-1/2 inch length under head.

Installation Notes

Installation is typically performed by carpenters, ironworkers, millwrights, or general maintenance technicians using a standard socket or box-end wrench on the nut side. A flat washer and nut should be used on the threaded end to distribute load and secure the connection. Ensure the pre-drilled hole diameter is appropriate for the 5/8 inch shank to allow the square neck to seat flush and prevent rotation. Follow applicable structural or mechanical codes for required torque and fastener grade specifications for the assembly.
