Design: Carriage bolts have a distinctive domed head with a square section beneath it. The square section is designed to prevent the bolt from rotating when tightening the nut, making it ideal for applications where you need a flush, finished appearance on the surface. Material: Carriage bolts are typically manufactured from steel, although they can also be found in stainless steel or other materials. The choice of material depends on the specific application requirements, such as corrosion resistance or load-bearing capacity. Thread: The thread of a carriage bolt is typically coarse and fully threaded from the tip to just below the head. This allows for a secure and tight connection when used with a corresponding nut. Square Neck: One distinctive feature of a carriage bolt is its square neck, which is designed to fit into a square hole in the material being fastened. The square neck prevents the bolt from spinning during installation, making it easier to tighten the nut. Applications: Carriage bolts are commonly used in applications where a secure fastening is required, such as in furniture assembly, wooden structures, machinery, and outdoor construction projects. They are often used in combination with a washer and a nut to provide a strong joint.
