Value Collection CAI502501500-100BX Carriage Bolt 1/4-20

Product Description

The VALUE COLLECTION CAI502501500-100BX is a 1/4-20 carriage bolt with a 1-1/2 inch length under head, designed for general fastening applications across trade and industrial settings. Built from Grade 5 steel with a zinc-plated finish, it offers a balance of tensile strength and corrosion resistance suitable for indoor and light outdoor use. The square neck beneath the domed head locks into wood or soft substrate to prevent rotation during tightening. This bolt is sold in a minimum order quantity of 100 units per box, making it practical for bulk job-site stocking or maintenance inventory.

Carriage bolts in this size range see regular use in structural wood connections, equipment mounting, HVAC equipment bases, electrical panel supports, and general mechanical assemblies. The 1/4-20 UNC thread is one of the most common inch-series thread specifications, compatible with standard 1/4-20 hex nuts and lock nuts. The zinc plating provides a baseline level of protection against oxidation in dry to moderately humid environments. Tradespeople in HVAC, electrical, and general construction frequently carry this fastener size as a standard consumable.

Key Features

• Grade 5 steel construction for reliable tensile and proof load strength
• Zinc-plated finish provides corrosion resistance in dry and moderately humid environments
• Square neck prevents bolt rotation when tightening a nut from the opposite side
• 1/4-20 UNC thread mates with standard inch-series nuts and threaded hardware
• 1-1/2 inch length under head suits medium-thickness connection applications
• Sold in 100-count box for efficient job-site and shop stocking

Compatibility

Designed as a standard inch-series fastener compatible with any application requiring a 1/4-20 UNC carriage bolt with a 1-1/2 inch length under head and square neck profile.

Installation Notes

Insert the bolt through a pre-drilled hole sized to allow the square neck to seat flush and prevent rotation before threading the nut. Tighten the nut from the exposed end using the appropriate wrench; no tool is needed on the bolt head when the neck is properly seated. Always torque fasteners to values specified by the structural or equipment drawing for the application. Inspect zinc-plated fasteners used in exterior or wet locations, as this finish is not rated for prolonged moisture exposure.
