Value Collection CAI503702000-100BX Carriage Bolt 3/8-16 2in

Product Description

The VALUE COLLECTION CAI503702000-100BX is a 3/8-16 carriage bolt with a 2-inch length under head, designed for general fastening applications in structural, mechanical, and construction assemblies. Manufactured from Grade 5 steel with a zinc plating finish, this bolt provides reliable corrosion resistance and tensile strength for indoor and light outdoor use. The square neck beneath the domed head seats into pre-drilled holes to prevent rotation during nut tightening, eliminating the need for a secondary tool on the bolt side. Sold in a box of 100, this fastener suits bulk procurement for production or job-site use.

This carriage bolt is suited for wood-to-wood and wood-to-metal connections commonly found in framing, equipment mounting, and fixture installation. The 3/8-16 UNC thread pattern is a widely used coarse-thread standard, compatible with 3/8-16 hex nuts and flat washers. Typical applications include deck construction, structural framing, mechanical equipment mounting, and general trade work where a flush, tamper-resistant bolt head is required on the finished side of the assembly.

Key Features

• Grade 5 steel construction for high tensile strength in structural fastening
• Zinc-plated finish provides corrosion resistance for light outdoor and indoor environments
• Square neck prevents bolt rotation during installation without a secondary wrench
• 3/8-16 UNC coarse thread for broad compatibility with standard hardware
• 2-inch length under head suits medium-depth material stacks
• Box quantity of 100 supports bulk job-site or production use

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts and washers in wood, composite, or metal applications requiring a round-head, square-neck carriage bolt per inch-system fastener standards.

Installation Notes

Installation is performed by driving the bolt through a pre-drilled clearance hole sized for the shank diameter, then seating the square neck fully into the material to prevent spin. A standard hex nut and washer are applied to the threaded end and tightened with a wrench or socket. Follow applicable building codes and torque specifications for the joint class when used in structural connections. Do not install in applications requiring stainless steel or a higher-grade fastener where corrosion or load demands exceed Grade 5 zinc-plated specifications.
