Value Collection CAI207504500-020BX Carriage Bolt 3/4-10

Product Description

The VALUE COLLECTION CAI207504500-020BX is a 3/4-10 UNC carriage bolt with a 4.5-inch length under head, manufactured from Grade 2 steel with a zinc-plated finish. The round dome head and square neck design pull into the work surface as the nut is tightened, preventing rotation without requiring a wrench on the bolt head. Meets ASTM A307 fastener standards. Weighing approximately 0.60 pounds, this bolt is suited for general structural and construction fastening applications where corrosion resistance and a smooth finished head are required.

Carriage bolts in this size range are commonly used in wood-to-wood and wood-to-metal connections in construction, framing, and equipment assembly. The 3/4-10 thread size and 4.5-inch under-head length make it appropriate for applications involving thicker stock or multi-layer assemblies. The zinc plating provides moderate corrosion resistance suitable for dry and semi-exposed interior environments. Installation is straightforward and does not require specialized tools beyond a standard wrench or socket for the mating nut.

Key Features

• 3/4-10 UNC thread size with 4.5-inch length under head
• Square neck prevents bolt rotation during nut tightening without a secondary tool
• Grade 2 steel construction meets ASTM A307 standards
• Zinc-plated finish for moderate corrosion resistance
• Inch measurement system; compatible with standard UNC hardware

Compatibility

Designed as a standard 3/4-10 UNC carriage bolt for general-purpose fastening applications requiring a flush round head and square-neck anti-rotation design.

Installation Notes

Installation typically requires drilling a through-hole sized to match the bolt shank diameter so the square neck seats flush and locks against rotation. Apply a flat washer and hex nut on the threaded end and tighten with a standard wrench or socket. Power down or de-energize any adjacent electrical equipment before working in the installation area. Follow applicable structural and building codes for fastener spacing and load requirements.
