Value Collection CAI203102000-10LBBX Carriage Bolt 5/16-18

Product Description

The VALUE COLLECTION CAI203102000-10LBBX is a 5/16-18 carriage bolt with a 2-inch length under head, designed for general fastening applications where a clean, round head finish and reliable clamping strength are required. Constructed from Grade 2 steel with a zinc-plated finish, this bolt resists corrosion in light-duty environments and meets standard UNC thread specifications. The square neck directly beneath the head locks into wood or soft material to prevent spinning during nut tightening, making installation straightforward without needing a secondary tool to hold the fastener. Plumbers, electricians, HVAC technicians, and general contractors use carriage bolts like this for equipment mounting, structural connections, and bracket assembly.

This carriage bolt suits residential and light commercial applications where inch-system fasteners are required. Common uses include securing equipment frames, mounting panels, connecting wood-to-metal assemblies, and general structural fastening tasks encountered during mechanical, electrical, and plumbing installations. The 5/16-18 UNC thread size is widely compatible with standard hex nuts and washers available through most trade suppliers.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard inch-system hardware
• 2-inch length under head suits medium-depth fastening applications
• Square neck prevents bolt rotation during tightening without a secondary tool
• Grade 2 steel construction provides adequate tensile strength for general-purpose use
• Zinc-plated finish offers light corrosion resistance in dry and semi-exposed environments

Compatibility

Designed as a general-purpose inch-system carriage bolt compatible with standard 5/16-18 UNC hex nuts, washers, and coupling nuts used in residential and light commercial fastening applications.

Installation Notes

Carriage bolts are typically installed by trade professionals and general contractors using standard hand or power tools. Insert the bolt through a pre-drilled hole sized to the shank diameter so the square neck seats flush and resists turning. Thread a hex nut onto the exposed end and tighten with a wrench — no tool is needed on the bolt head side once the neck is seated. Confirm the hole substrate material is appropriate for the load before torquing.
