Head Design: Carriage bolts have a rounded, domed head, which provides a smooth, finished appearance when installed. The head is typically countersunk into the surface of the material, creating a flush or slightly raised finish.
Square Neck: Beneath the head of the carriage bolt, there is a square section known as the neck or shank. This square neck prevents the bolt from rotating when installed, ensuring a secure and stable connection.
Threaded Shaft: Carriage bolts have a fully threaded shaft that extends from the head to the end of the bolt. The threads are standard coarse threads, allowing for compatibility with nuts or threaded holes.
Materials: Carriage bolts are commonly made from steel, stainless steel, or brass, depending on the application requirements. Stainless steel carriage bolts are often used in outdoor or marine applications due to their corrosion resistance.
Sizes: Carriage bolts are available in a variety of sizes, including different diameters and lengths, to accommodate various applications. They are typically designated by their diameter, length, and thread pitch (e.g., 1/4"-20 x 2" carriage bolt).
Applications: Carriage bolts are commonly used in woodworking, construction, and outdoor applications where a secure and visually appealing fastening solution is required. They are often used to fasten wood to wood, wood to metal, or wood to concrete.
