Cup square hex bolts and nuts, otherwise know as carriage bolts or coach bolts, are generally used in wood. They consist of a plain domed head with a square neck underneath. As the nut is tightened the square pulls into the wood creating a very secure fit and preventing the bolt from turning. Because the head is totally plain, cup square hex bolts make a popular choice where a secure fixing or an enhanced finish is required.
