CARRIAGE BOLT

A carriage bolt, also known as a coach bolt, is a type of threaded fastener designed with a domed or rounded head and a square shoulder beneath it. Carriage bolts are typically made of steel or stainless steel, providing strength and durability. The distinctive feature of a carriage bolt is the square shoulder or neck beneath the head, which helps prevent rotation when tightening or loosening the bolt. This makes carriage bolts suitable for applications where a smooth exterior surface is desired or where the bolt should not spin when tightened. Carriage bolts are commonly used in woodworking, construction, and other industries where a strong and secure fastening is required. They are often used in conjunction with a nut and washer, with the square shoulder fitting into a corresponding square hole to prevent the bolt from turning while tightening the nut. Carriage bolts are versatile and reliable fasteners, providing a secure and stable connection in a variety of applications.
