Value Collection CAI202503500-10LBBX Carriage Bolt 1/4-20

Product Description

The VALUE COLLECTION CAI202503500-10LBBX is a 1/4-20 UNC carriage bolt with a 3.5-inch length under the head and a square neck profile. It is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance for general-purpose fastening applications. The square neck seats into pre-drilled holes to prevent rotation during tightening, eliminating the need for a wrench on the bolt head. This fastener is commonly installed by general contractors, maintenance technicians, electricians, and plumbers when securing wood-to-wood or wood-to-metal connections in mechanical and structural assemblies.

This carriage bolt is suited for light-duty structural and mechanical fastening in residential and commercial construction and maintenance work. Typical applications include fastening lumber framing, securing equipment mounting brackets, assembling utility shelving, and anchoring components in low-stress structural connections. The zinc plating makes it appropriate for indoor and dry-environment installations where mild corrosion resistance is sufficient. It follows the inch measurement system with a UNC thread standard, making it compatible with standard 1/4-20 nuts and hardware across trade and construction applications.

Key Features

• 1/4-20 UNC thread size for compatibility with standard inch-system fastener hardware
• 3.5-inch length under head accommodates moderate material stack thickness
• Square neck prevents bolt rotation when tightening nut without holding the head
• Grade 2 steel construction provides adequate strength for general-purpose light-duty connections
• Zinc-plated finish offers basic corrosion resistance for dry or indoor environments

Compatibility

Designed as a general-purpose inch-system carriage bolt compatible with standard 1/4-20 UNC nuts and washers used in residential and commercial fastening applications.

Installation Notes

Installation is typically performed by general contractors, maintenance technicians, or trade professionals as part of structural or equipment-mounting work. Drill a clean through-hole sized to allow the square neck to seat flush and resist rotation before driving the bolt through. Apply a standard 1/4-20 nut and washer on the opposite face and tighten to the connection requirements specified by the applicable building or mechanical code. Do not use impact tools at high torque settings on Grade 2 fasteners, as this grade has lower proof load limits than Grade 5 or Grade 8 hardware.
