Value Collection CAI507506000-020BX Carriage Bolt 3/4-10 6 in

Product Description

The VALUE COLLECTION CAI507506000-020BX is a 3/4-10 carriage bolt with a 6-inch length under head, manufactured from Grade 5 steel with a zinc-plated finish. The square neck under the domed head resists rotation during installation, allowing the nut to be tightened from one side without a wrench on the bolt head. The zinc plating provides a baseline level of corrosion resistance suitable for general structural and mechanical fastening applications. This bolt follows inch-system UNC (Unified National Coarse) thread standards and is sold individually.

Carriage bolts in this size range are used across a broad range of trade and construction applications, including wood-to-wood connections, equipment mounting, structural framing, and general assembly work. The 3/4-10 UNC thread is a common coarse-thread specification found in structural steel, treated lumber connectors, and heavy equipment frames. Installation requires a standard flat washer and hex nut on the through-side. The Grade 5 rating indicates medium-strength steel suitable for general-purpose load-bearing connections where high-tensile-grade hardware is not specified.

Key Features

• 3/4-10 UNC coarse thread for broad hardware compatibility
• 6-inch length under head accommodates thicker material stacks
• Square neck locks into wood or soft substrates to prevent spinning during torque application
• Grade 5 steel provides medium-strength structural performance
• Zinc-plated finish offers corrosion resistance for indoor and dry outdoor use
• Inch measurement system with length measured under head per standard fastener convention

Compatibility

Designed as a standard 3/4-10 UNC inch-system carriage bolt suitable for general structural fastening applications where a Grade 5 zinc-plated fastener is specified.

Installation Notes

Installation typically requires drilling a clean through-hole sized to the bolt shank diameter before seating the square neck flush with the substrate surface. Power down or de-energize any adjacent electrical equipment before working in proximity to live panels or junction boxes. Apply a flat washer and appropriately rated hex nut on the through-side, and tighten to the torque value specified in the relevant structural or equipment documentation. Fastener replacement in structural applications should be performed by a qualified tradesperson in accordance with applicable building codes.
