A carriage bolt, also known as a coach bolt or round head square neck bolt is a form of bolt used to fasten metal to wood.

It is distinguished from other bolts by its shallow mushroom head and that the shank cross-section of the bolt is circular for most of its length, as usual, but the portion immediately beneath the head is formed into a square section. This makes the bolt self-locking when placed through a square hole in a metal strap, or a round hole in most wood. This allows the fastener to be installed with only a single tool, a spanner or wrench, working from one side. The head of a carriage bolt is a shallow dome. The squared section is of the same size as the diameter of the bolt shank, with a plain unthreaded shank.
