Value Collection CAI207503000-020BX Carriage Bolt 3/4-10

Product Description

The VALUE COLLECTION CAI207503000-020BX is a 3/4-10 UNC carriage bolt with a 3-inch length under head and a square neck drive style. Made from Grade 2 steel with a zinc-plated finish, this fastener meets ASTM A307 standards for general-purpose structural and mechanical applications. The square neck seats firmly into wood or pre-drilled material to prevent rotation during installation without requiring a wrench on the bolt head. At 0.451 pounds, it is a solid, full-sized fastener suited for light structural connections, equipment mounting, and general fabrication work handled by contractors, maintenance techs, and experienced DIYers.

This carriage bolt is used in residential and light commercial construction, wood framing, deck and fence assembly, and mechanical equipment mounting. Its zinc plating provides basic corrosion resistance for dry to mildly exposed indoor and covered outdoor environments. The ASTM A307 rating makes it appropriate for general structural bolt applications where high-strength grades are not required. It is sold individually, making it a practical option for small repairs or single-unit replacements.

Key Features

• 3/4-10 UNC thread size for broad compatibility with standard 3/4-inch nuts and hardware
• 3-inch length under head suits typical structural lap joints and through-bolt connections
• Square neck design resists bolt rotation during nut tightening without head tooling
• Grade 2 steel construction meets ASTM A307 general-purpose structural requirements
• Zinc-plated finish provides basic corrosion resistance in dry and covered environments

Compatibility

Designed as a standard inch-system carriage bolt compatible with 3/4-10 UNC nuts and threaded hardware conforming to ASTM A307 specifications.

Installation Notes

Installation is typically performed by carpenters, general contractors, or maintenance technicians using a standard wrench or socket on the nut side. Pre-drill the mating material to the correct diameter so the square neck seats flush and locks without spinning. Torque should be applied to the nut only. Follow applicable building codes and structural connection specifications for the project type when determining fastener quantity and layout.
