Value Collection -32160-11/2 Carriage Bolt 5/16-18 1-1/2 in

Product Description

The VALUE COLLECTION -32160-11/2 is a fully threaded carriage bolt designed for general fastening applications in structural and mechanical assemblies. Built to a 5/16-18 UNC thread specification, this bolt measures 1.5 inches in length under the head and features a square neck that locks into place when driven into a mating surface, preventing rotation during nut tightening. Manufactured from Grade 5 steel with a zinc trivalent chromate finish, it delivers reliable corrosion resistance and meets SAE J429 strength standards. Tradespeople and assemblers use this bolt where a clean, low-profile domed head and self-locking neck are required.

This carriage bolt is suited for wood-to-wood, wood-to-metal, and light structural connections across a wide range of trade and industrial applications. Typical install scenarios include equipment mounting, bracket assemblies, HVAC equipment support structures, electrical enclosure mounting, and general fabrication work. The fully threaded shank provides maximum engagement length for the given fastener size, making it a practical choice where thin material stacks are common.

Key Features

• 5/16-18 UNC thread for broad nut and insert compatibility
• Square neck design prevents spinning during installation without a secondary tool
• Fully threaded shank maximizes thread engagement across the fastener length
• Grade 5 steel construction meets SAE J429 mechanical requirements
• Zinc trivalent chromate finish provides corrosion resistance for indoor and light-duty outdoor use
• Inch measurement system; length stated as length under head at 1.5 inches

Compatibility

Designed as a standard UNC carriage bolt for use with 5/16-18 hex nuts, flange nuts, and compatible threaded inserts in wood, metal, and composite material assemblies.

Installation Notes

Installation is performed by inserting the bolt through a pre-drilled hole sized to allow the square neck to seat flush, then securing with a standard 5/16-18 nut and washer. No wrench is needed on the bolt head once the neck is seated, but the mating hole must be sized correctly to allow neck engagement. Follow applicable torque guidelines for Grade 5 fasteners per SAE J429. Fastener replacement in electrical or HVAC equipment should be performed with the system de-energized or shut down per applicable NEC or equipment-specific lockout procedures.
