Value Collection 489092PR Carriage Bolt 3/8-16 9 Inch

Product Description

The VALUE COLLECTION 489092PR is a 3/8-16 carriage bolt with a 9-inch length under the head, manufactured from Grade 2 steel with a zinc-plated finish. The square neck seats into wood or other soft materials to prevent rotation during fastening, eliminating the need for a wrench on the bolt side. Conforming to ASTM A307 standards, this bolt is suited for general-purpose structural and mechanical assembly work. Installers and tradespeople working in light construction, equipment mounting, and fixture installation will find this a reliable stock fastener for standard load applications.

This carriage bolt is commonly used in wood-to-wood and wood-to-metal connections across residential and light commercial construction. Typical applications include deck framing, fence assembly, equipment frames, and utility structures. The zinc plating provides basic corrosion resistance in indoor and sheltered outdoor environments. The 3/8-16 UNC thread pattern is widely compatible with standard hex nuts and washers available from any fastener supplier.

Key Features

• 3/8-16 UNC thread for compatibility with standard hardware
• 9-inch length under head for deeper through-fastening applications
• Square neck resists rotation when drawn into wood without requiring a second tool
• Grade 2 steel construction meets ASTM A307 fastener standards
• Zinc-plated finish provides corrosion resistance in sheltered environments

Compatibility

Designed as a general-purpose carriage bolt compatible with standard 3/8-16 UNC hex nuts and washers in wood and light metal fastening assemblies.

Installation Notes

Carriage bolts are typically installed by tradespeople and general contractors using a hammer to seat the square neck flush into the mating material, then tightening the nut from the opposite side with a wrench or socket. Always use an appropriate flat washer and hex nut rated for the load. Follow applicable building codes and structural requirements for the specific application. Do not overtighten in wood substrates, as this can cause crushing and reduce joint integrity.
