3/8 carriage bolts are a specific size of carriage bolts commonly used in construction and woodworking applications. These bolts feature a smooth, rounded head and a square neck beneath the head, allowing for secure fastening without the need for a wrench on the head side. The 3/8 size designation refers to the diameter of the bolt shank. These bolts are often used in applications where a balance between strength and size is required, such as in furniture assembly, framing, and general construction.
