Cup Square Hex Bolts and Nuts
Cup square hexagon bolts and nuts (also known as CARRIAGE BOLTS or COACH BOLTS) are mostly used in wood. They have a plain domed head with a square neck underneath. The square pulls into the wood as the nut is tightened for a very secure fit, preventing the bolt from turning. As the head is completely plain they make a popular choice where a secure or decorative finish is required.
