Value Collection -32164-2 Carriage Bolt 3/8-16 2in Grade 5

Product Description

The VALUE COLLECTION -32164-2 is a 3/8-16 UNC carriage bolt with a 2-inch length under head, designed for general fastening applications where a smooth, rounded head and a non-rotating square neck are required. Manufactured from Grade 5 steel with a zinc-plated finish, this bolt provides solid mechanical strength and basic corrosion resistance for indoor and light outdoor use. The square neck locks into the workpiece material during tightening, eliminating the need for a wrench on the bolt head. It is a standard inch-system fastener used by tradespeople, contractors, and maintenance professionals across a wide range of structural and mechanical assemblies.

This carriage bolt is suited for wood-to-wood, wood-to-metal, and light structural connections in residential construction, equipment assembly, and general trade work. The zinc plating makes it appropriate for dry or mildly humid environments. Minimum order quantity is 50 pieces, sold in single-piece package quantity increments.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard nuts and tapped fittings
• 2-inch length under head for medium-depth fastening applications
• Square neck prevents bolt rotation during nut tightening without a secondary tool
• Grade 5 steel construction meets standard medium-strength fastener requirements
• Zinc-plated finish provides basic corrosion resistance in dry and low-humidity environments

Compatibility

Designed as a standard 3/8-16 UNC inch-system carriage bolt compatible with any 3/8-16 hex nut or coupling nut used in general construction and mechanical assembly applications.

Installation Notes

Installation is typically performed by carpenters, general contractors, or maintenance technicians using a standard wrench or socket on the mating nut. Drill a hole sized to the bolt diameter through the mating material so the square neck seats flush and locks. Tighten the nut from the threaded end only — the square neck resists rotation in wood or soft substrates but may require a backup wrench in metal applications. Follow applicable building codes when used in structural connections.
