Value Collection CAI502502250-100B Carriage Bolt 1/4-20

Product Description

The VALUE COLLECTION CAI502502250-100B is a 1/4-20 carriage bolt with a 2-1/4 inch length under head and a square neck drive style. Made from Grade 5 steel with a zinc-plated finish, this fastener is built for general-purpose structural and mechanical assembly work. The square neck seats flush into pre-drilled material to prevent rotation during installation, eliminating the need for a wrench on the bolt head. It follows Unified National Coarse (UNC) thread standards and is measured by length under head per inch-system conventions. Suitable for trade and light industrial applications where corrosion resistance and moderate tensile strength are required.

This carriage bolt is commonly used in wood-to-wood, wood-to-metal, and light structural connections across construction, HVAC equipment mounting, electrical enclosure assembly, and general maintenance applications. The zinc coating provides baseline corrosion resistance for indoor and sheltered outdoor installations. Sold in a minimum order quantity of 100 pieces, making it appropriate for contractors and maintenance shops stocking hardware for recurring job needs.

Key Features

• 1/4-20 UNC thread for compatibility with standard nuts and tapped holes
• 2-1/4 inch length under head for medium-depth fastening applications
• Square neck prevents bolt rotation during nut tightening without a secondary tool
• Grade 5 steel construction provides solid tensile strength for general structural use
• Zinc-plated finish offers baseline corrosion protection in dry or sheltered environments
• Sold in 100-piece increments suited for job-site and shop inventory

Compatibility

Designed as a standard 1/4-20 UNC carriage bolt suitable for use with any standard 1/4-20 hex nut or coupling nut in general structural, mechanical, and equipment-mounting applications.

Installation Notes

Installation is performed by hand or with common shop tools and does not require specialty equipment. Insert the bolt through a pre-drilled hole so the square neck seats fully into the material before threading the nut. Tighten the nut from the opposite side using an appropriate wrench or socket; the seated square neck holds the bolt stationary. Ensure the pre-drilled hole diameter matches the bolt shank to allow the square neck to seat properly and prevent spinning.
