Value Collection CAI506206000-025BX Carriage Bolt 5/8-11 6 in

Product Description

The VALUE COLLECTION CAI506206000-025BX is a 5/8-11 carriage bolt with a 6-inch length under head, designed for general structural and fastening applications across construction, mechanical, and trade installations. The square neck below the domed head locks into wood or other soft material to prevent rotation during tightening, eliminating the need for a second wrench on the bolt side. Manufactured from Grade 5 steel with a zinc-plated finish, this bolt delivers solid tensile strength and basic corrosion resistance suitable for interior and sheltered exterior use. It weighs 0.552 pounds and conforms to the inch system of measurement with UNC (Unified National Coarse) threading.

This carriage bolt is suited for timber framing, decking, rail assemblies, equipment mounting, and light structural connections where a smooth, rounded bolt head is required on the visible face. The zinc plating provides a protective coating against moisture and oxidation in moderate environments. It is used by carpenters, electricians, HVAC installers, and general contractors when securing structural members, brackets, or equipment frames. The 5/8-11 UNC thread size is a common coarse-thread standard readily matched to standard hex nuts, washers, and coupling nuts.

Key Features

• 5/8-11 UNC coarse thread for broad nut and hardware compatibility
• 6-inch length under head accommodates thick stock and multi-layer assemblies
• Square neck resists rotation when driven into wood or soft material, no secondary wrench needed
• Grade 5 steel construction meets standard tensile and proof-load requirements for structural fastening
• Zinc-plated finish provides corrosion protection for interior and sheltered exterior environments

Compatibility

Designed as a standard inch-series carriage bolt compatible with 5/8-11 UNC hex nuts, flat washers, and lock washers in typical structural and general-purpose fastening applications.

Installation Notes

Installation is typically performed by carpenters, general contractors, or trade professionals using a standard socket wrench or box wrench on the nut side. Power down or de-energize any adjacent electrical equipment before working in confined structural spaces. Insert the bolt through the pre-drilled hole so the square neck seats flush in the material, then thread the nut by hand before applying torque. Do not overtighten in wood substrates, as the square neck can pull through the material if force is excessive.
