Value Collection CAI2-1002500-100BX Carriage Bolt 10-24

Product Description

The VALUE COLLECTION CAI2-1002500-100BX is a 10-24 UNC carriage bolt with a 2-1/2 inch length under head and a square neck drive style. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener is built to ASTM A307 standards for general-purpose structural and mechanical applications. The square neck seats flush into wood or soft material to prevent rotation during installation, eliminating the need for a wrench on the bolt head. This bolt is sold in a minimum order quantity of 100 pieces, making it well suited for production assembly, repair work, or job-site stocking.

Carriage bolts in this size range are commonly used in wood-to-wood and wood-to-metal connections across residential construction, HVAC equipment mounting, light structural framing, fence and deck assembly, and general mechanical trade applications. The zinc coating provides a baseline level of corrosion resistance suitable for dry and mildly humid indoor environments. Installation is straightforward and does not require special tooling beyond a standard nut driver or wrench on the mating nut.

Key Features

• 10-24 UNC thread form for compatibility with standard inch-series hardware
• 2-1/2 inch length under head for moderate-depth fastening applications
• Square neck resists rotation when driven into wood or soft substrates
• Grade 2 steel construction meets ASTM A307 fastener standard
• Zinc-plated finish provides baseline corrosion resistance in dry environments
• Sold in multiples of 100 for job-site and production use

Compatibility

Designed as a standard inch-series carriage bolt for general-purpose fastening in wood, metal, and mixed-material connections where a 10-24 UNC thread and 2-1/2 inch under-head length are specified.

Installation Notes

Installation is performed by driving the square neck into a pre-drilled hole sized to grip the neck and prevent spin, then threading a standard hex nut onto the exposed end. Apply a flat washer under the nut to distribute clamping load and protect the mating surface. Follow applicable building or mechanical codes when specifying fastener grade for structural connections. Do not substitute Grade 2 hardware in applications requiring Grade 5 or higher rated fasteners.
