Value Collection CAI502506000-100BX Carriage Bolt 1/4-20 6in

Product Description

The VALUE COLLECTION CAI502506000-100BX is a 1/4-20 carriage bolt with a 6-inch length under the head, manufactured from Grade 5 steel with a zinc-plated finish. The square neck below the domed head pulls into the work material when the nut is tightened, preventing rotation without a wrench on the bolt side. These fasteners are used across a wide range of trade and light structural applications where a smooth, finished head is required on the visible face. The zinc coating provides a basic level of corrosion resistance for indoor and sheltered installations. Sold in a minimum order quantity of 100 pieces per box.

This carriage bolt is suited for wood-to-wood, wood-to-metal, and similar through-bolt connections found in HVAC equipment bases, electrical enclosure mounting, structural framing, and general mechanical assemblies. The 1/4-20 UNC thread pattern is one of the most common thread standards in inch-system fastener applications, making hardware and replacement nuts easy to source. The 6-inch length under the head accommodates thicker material stacks or applications requiring extended thread engagement.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard inch-system hardware
• 6-inch length under head suits thick material stacks and extended-reach installations
• Square neck locks the bolt in place during nut tightening, no secondary tool needed on bolt head
• Grade 5 steel construction provides increased tensile strength over Grade 2
• Zinc-plated finish delivers basic corrosion resistance for sheltered environments
• Box quantity of 100 supports bulk service and installation work

Compatibility

Designed as a standard inch-system carriage bolt for general-purpose through-bolt fastening applications using 1/4-20 UNC nuts and washers.

Installation Notes

Installation is performed with a standard wrench or socket on the nut side only — the square neck seats into the substrate to hold the bolt stationary. Ensure the mounting hole diameter is sized to allow the square neck to seat flush and lock properly. For structural or load-bearing applications, verify that Grade 5 fasteners meet the specification requirements of the applicable code or engineering standard before installation. Use appropriate washers to distribute clamping load and prevent surface damage.
