Value Collection CAI203711000-025BX Carriage Bolt 3/8-16

Product Description

The VALUE COLLECTION CAI203711000-025BX is a 3/8-16 UNC carriage bolt with an 11-inch length under head and a square neck design. Made from Grade 2 steel with a zinc-plated finish, this fastener meets ASTM A307 standards. The square neck seats into the work surface when driven, preventing rotation during nut tightening without requiring a wrench on the bolt head. This bolt is suited for structural and general-purpose fastening applications in construction, framing, and equipment assembly where a flush, tamper-resistant head profile is required.

This carriage bolt is appropriate for wood-to-wood and wood-to-metal connections in residential and light commercial construction. The zinc plating provides basic corrosion resistance for indoor and protected outdoor installations. Typical applications include deck framing, stair assemblies, playground equipment, and general structural fastening where UNC thread engagement and ASTM A307 compliance are specified. This bolt is sold in a minimum order quantity of 25 pieces per order.

Installation Notes

Installation is performed by tradespeople and general contractors using standard hand tools. The bolt head should be driven into the mating material until the square neck is fully seated and flush before threading the nut. Power down or de-energize any adjacent electrical components before working in proximity to electrical systems. Follow applicable building codes and project specifications for torque and fastener pattern requirements.
