Carriage Bolts, also called Coach Bolts are usually used to fasten metal to metal or metal to wood. The square neck locks the bolt in place while the nut is tightened. Carriage bolts can have either a square or hex head, and may have a ribbed neck rather than a square neck. These bolts were originally used in the construction of carriages and their wheels which is where they get their name.
Carriage bolts are round dome-headed bolts threaded along part of the shank. They are inserted into pre-drilled holes, and the shape of the neck locks into the wood and stops the bolt from turning as it is tightened. The various types of carriage bolts include round neck ribbed neck bolts, round head short neck bolts, flat head square neck bolts, and fin neck bolts.
Common applications of Carriage Bolts are:
- • Wood to metal fastening
- • Wood to wood connections
- • Water treatment systems
