Value Collection CAI502505000-100BX Carriage Bolt 1/4-20 5 in

Product Description

The VALUE COLLECTION CAI502505000-100BX is a 1/4-20 UNC carriage bolt with a 5-inch length under head and a square neck drive style. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers reliable corrosion resistance and mechanical strength in structural and general-purpose assembly applications. The square neck seats flush into wood or pre-drilled channel to prevent rotation during tightening, eliminating the need for a second wrench on the bolt head. This bolt is sold in a minimum order quantity of 100 pieces, making it well suited for contractors and tradespeople managing bulk fastener inventory on the job site.

This carriage bolt is appropriate for light structural connections, wood-to-wood assemblies, equipment mounting, and general fabrication tasks encountered in residential and light commercial construction. Electricians, HVAC installers, plumbers, and general contractors commonly use 1/4-20 carriage bolts to secure strut channel, equipment mounting plates, and framing components. The zinc plating makes it suitable for dry and mildly humid indoor environments where moderate corrosion resistance is required.

Key Features

• 1/4-20 UNC thread size provides broad compatibility with standard nuts and threaded hardware
• 5-inch length under head accommodates thicker material stacks and standoff applications
• Square neck prevents bolt rotation during installation without a secondary tool
• Grade 5 steel construction offers higher tensile strength than standard Grade 2 fasteners
• Zinc-plated finish provides corrosion resistance in dry and mildly humid environments
• Sold in multiples of 100 to support bulk job-site and shop inventory needs

Compatibility

Designed as a standard 1/4-20 UNC carriage bolt for use with any compatible 1/4-20 hex nut, lock nut, or wing nut and suitable for wood, steel, and composite material assemblies requiring a square-neck anti-rotation fastener.

Installation Notes

Install using a standard wrench or socket on the nut side only — the square neck seats into the material to hold the bolt stationary. Pre-drill a hole sized to the bolt shank diameter to allow the square neck to draw flush on seating. Do not overtighten past material or fitting specifications, as Grade 5 fasteners can strip softer materials at excessive torque. Follow applicable building codes and fastener standards for structural applications.
