Carriage bolts, also known as coach bolts or cup squares, are a type of fastener that are commonly used in construction and woodworking projects. These bolts feature a round head with a square shoulder that is designed to prevent the bolt from turning once it is tightened in place.

One of the main benefits of carriage bolts is their ability to provide a secure and stable connection between two pieces of wood or other materials. The square shoulder on the bolt is designed to fit snugly against the wood, preventing the bolt from turning or sliding out of place. This makes them ideal for use in applications where a strong and reliable connection is needed, such as building decks, fences, and other outdoor structures.

Another benefit of carriage bolts is their versatility. They come in a variety of sizes and can be used with a variety of different materials, including wood, metal, and plastic. This makes them a versatile option for a wide range of projects, whether you are building a deck, installing a fence, or working on a woodworking project.

When working with carriage bolts, it is important to use the correct tools and techniques. To install the bolt, you will need a drill, a tape measure, and a wrench or socket. The bolt should be inserted through the two pieces of wood or other materials that you are connecting and then tightened with a wrench or socket. Once the bolt is tightened, the square shoulder on the bolt should be flush against the wood, ensuring a secure and stable connection.

Carriage bolts can be found in a variety of finishes, including zinc plated and hot-dip galvanized. Zinc plating is a common finish for carriage bolts and provides corrosion resistance, while hot-dip galvanized is a more heavy-duty finish that provides even greater corrosion resistance.

In conclusion, carriage bolts are a reliable and versatile option for a wide range of construction and woodworking projects. They offer a secure and stable connection, and can be used with a variety of materials and finishes. With the right tools and techniques, you can easily install carriage bolts to provide a strong and stable connection for your project.
