Value Collection CAI502502500-100BX Carriage Bolt 1/4-20

Product Description

The VALUE COLLECTION CAI502502500-100BX is a 1/4-20 UNC carriage bolt designed for general fastening applications in construction, equipment assembly, and structural connections. The bolt features a smooth domed head and a square neck that locks into wood or soft material to prevent rotation during installation. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers reliable tensile strength and basic corrosion resistance. The length under head measures 2-1/2 inches. Sold in a minimum order quantity of 100 pieces, making it practical for job-site stock or production use.

This carriage bolt is suited for residential and light commercial applications including wood framing, deck construction, playground equipment, metal-to-wood connections, and general fabrication. The zinc plating provides a baseline level of corrosion protection appropriate for indoor and sheltered outdoor environments. Grade 5 steel provides a higher tensile strength than standard Grade 2 hardware, making it suitable for moderate-load structural connections where a reliable, rotation-resistant fastener is required.

Key Features

• 1/4-20 UNC thread for compatibility with standard imperial nuts and hardware
• Square neck design prevents bolt rotation during nut tightening without requiring a wrench on the head
• Grade 5 steel construction for improved tensile strength over standard hardware grades
• Zinc-plated finish provides basic corrosion resistance for sheltered and indoor use
• 2-1/2 inch length under head suits medium-depth through-bolt applications
• Sold in multiples of 100 for efficient job-site and production stocking

Compatibility

Designed as a standard 1/4-20 UNC imperial carriage bolt compatible with 1/4-20 hex nuts, washers, and standard imperial fastener hardware used in wood-to-wood and metal-to-wood assemblies.

Installation Notes

Installation typically requires drilling a clean through-hole sized to match the bolt shank diameter so the square neck seats flush and locks properly into the material. Drive the bolt through the workpiece until the square neck is fully seated, then apply a washer and nut to the threaded end and tighten with a standard wrench or socket. Do not use an impact driver directly on the domed head, as this can damage the head profile or dislodge the square neck seating. Follow applicable structural fastening guidelines from the building code authority having jurisdiction when used in load-bearing assemblies.
