Carriage bolts are a type of fastener used in woodworking and construction projects. They are often used to secure two pieces of wood together, or to attach hardware to a wooden surface. These bolts have a flat, rounded head and a square shoulder beneath the head that prevents them from turning when tightened. They are typically installed by inserting them through a pre-drilled hole and then tightening a nut on the other end. When selecting carriage bolts for a project, it is important to consider the size and length of the bolt. The size refers to the diameter of the bolt shaft, while the length refers to how far the bolt extends into the material. For example, a 5%16% 20 x 1 2 carriage bolt has a shaft diameter of 5/16 inches and a length of 1-1/2 inches. It is important to choose a bolt that is the appropriate size and length for the job to ensure a secure fit. One of the advantages of using carriage bolts is that they provide a clean, finished look. The rounded head sits flush with the surface of the material, creating a smooth and seamless appearance. This makes them an ideal choice for visible applications where aesthetics are important, such as furniture assembly or outdoor structures

Insert the bolt through the hole with the head on the side of the material where you want it to sit. Place a washer and nut on the other end of the bolt and tighten it with a wrench. The square shoulder beneath the head will prevent the bolt from turning as you tighten the nut, ensuring a secure connection.

Their clean appearance, strength, and ease of installation make them a popular choice for a variety of applications. Whether you are building furniture, constructing a deck, or securing hardware, carriage bolts are a practical and effective solution.
