A carriage bolt, also known as a coach bolt, is a type of fastener used to join two or more pieces of wood or metal together. It is characterized by its distinctive design, which includes a round head and a square or rectangular shank just below the head. The square or rectangular shank is designed to prevent the bolt from turning when it is tightened or loosened, making it a useful choice for applications where a secure connection is required.

Here are the key features of a carriage bolt:

1. Round Head: Carriage bolts have a round head that may be flat or domed. The head is typically smooth and may have a square neck beneath it.
2. Square or Rectangular Shank: The shank of a carriage bolt is square or rectangular in shape, which helps prevent it from rotating when it is installed. This feature is particularly useful when the bolt is used in wood, as it allows for a snug fit in a square hole.
3. Threaded End: The end of the carriage bolt opposite the head is threaded, allowing it to be screwed into a pre-drilled hole in the material being fastened. The threading on a carriage bolt is typically coarse and may be partially or fully threaded, depending on the specific design.
4. Nut and Washer: To secure a carriage bolt, a washer and nut are used. The square or rectangular shank prevents the bolt from spinning, allowing for easy tightening of the nut.
