Value Collection CAI203701000-10LBBX Carriage Bolt 3/8-16

Product Description

The VALUE COLLECTION CAI203701000-10LBBX is a 3/8-16 carriage bolt with a 1-inch length under the head, manufactured from Grade 2 steel with a zinc-plated finish. The square neck seats flush against the material surface to prevent rotation during tightening, eliminating the need for a wrench on the bolt head. The zinc coating provides baseline corrosion resistance for general-purpose fastening applications. This bolt follows the Unified National Coarse (UNC) thread standard and is sized in the inch measurement system. It is a standard stock fastener installed by tradespeople, maintenance technicians, and general contractors in a wide range of structural and mechanical assembly tasks.

This carriage bolt is suited for light- to medium-duty fastening in wood, metal, and composite assemblies. Common applications include equipment mounting, structural framing connections, brackets, and general mechanical assembly in residential, commercial, and industrial settings. The 3/8-16 thread size is widely used across HVAC equipment frames, electrical panel supports, plumbing equipment mounts, and general trade work where a tamper-resistant, flush-seating fastener is required.

Key Features

• 3/8-16 UNC thread for broad hardware compatibility
• Square neck design prevents rotation during installation without a backup wrench
• 1-inch length under head suits standard light- to medium-duty fastening applications
• Grade 2 steel construction provides adequate strength for general-purpose use
• Zinc-plated finish offers baseline corrosion resistance in dry or mildly humid environments

Compatibility

Designed as a standard 3/8-16 UNC carriage bolt for general-purpose fastening applications across trade and industrial assembly work.

Installation Notes

Install using a standard nut and washer on the through side; the square neck seats into a pre-drilled square or round hole to resist spinning during torquing. Power down or de-energize any associated equipment before fastening near electrical or mechanical assemblies. Do not use in applications requiring structural-grade fasteners without confirming the Grade 2 rating meets the load specification. Follow applicable building codes and manufacturer assembly instructions for the parent assembly.
