Carriage Bolt

Carriage bolts, coach bolt or round head square neck bolts are a type of bolt used to fasten metal to wood or metal strips. 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 usually a shallow dome. The squared section is of the same size as the diameter of the bolt shank, with a plain unthreaded shank.


Carriage bolt are used in covering of roofing. Carriage bolts are extensively used in security fixings, such as the Brenton Bolt where the bolt must only be removable from one side.
