Value Collection -32164-11/4 Carriage Bolt 3/8-16 1-1/4 in

Product Description

The VALUE COLLECTION -32164-11/4 is a 3/8-16 UNC carriage bolt with a 1-1/4 inch length under head and a square neck design. Manufactured from Grade 5 steel with a zinc-plated finish, it delivers reliable corrosion resistance and mechanical strength for general fastening applications. The square neck seats into the mating hole to prevent rotation during installation, eliminating the need for a wrench on the bolt head. Electricians, plumbers, HVAC technicians, and general tradespeople use carriage bolts like this to secure brackets, strut channel, equipment pads, and structural assemblies.

This carriage bolt is suited for light-to-medium duty fastening in both indoor and sheltered outdoor environments. The zinc plating provides baseline corrosion protection appropriate for dry or intermittently damp conditions. Typical applications include securing mechanical equipment mounts, pipe hangers, framing connections, and panel supports where a smooth domed head is required on the finished face of the assembly. Sold individually with a minimum order quantity of 50 pieces per order.

Key Features

• 3/8-16 UNC thread for compatibility with standard hex nuts and hardware
• 1-1/4 inch length under head provides correct grip range for typical light-duty assemblies
• Square neck locks into the workpiece to prevent spinning during nut tightening
• Grade 5 steel construction meets standard medium-strength fastener requirements
• Zinc-plated finish provides baseline corrosion resistance for indoor and sheltered use
• Smooth domed head presents a finished appearance on the exposed face of the joint

Compatibility

Designed as a standard 3/8-16 UNC carriage bolt suitable for use with any matching 3/8-16 hex nut, coupling nut, or threaded insert in inch-measurement fastener applications.

Installation Notes

Installation requires a standard hex nut and washer on the threaded end, tightened with an appropriately sized wrench or socket. The square neck must seat fully into the mating hole to prevent the bolt from rotating during torquing. Ensure the workpiece material and hole size are appropriate for a 3/8-inch carriage bolt before installation. Follow applicable structural or mechanical codes for fastener selection and torque requirements on the specific assembly.
