Different Types of Carriage Bolts, Their Properties, and Applications

Here are some of the most commonly used types of carriage bolts, along with their properties and application areas:

1. Round Head, Ribbed Neck: These carriage bolts are made from low carbon steel. These types of coach bolts have serrated or ribbed shoulders and feature a round head. They are mostly used in soft and ductile metals, plastics and wood.
2. Round Head, Short Neck: These bolts have a round head, and a short and square-shaped shoulder. They have a unified thread pitch, and are generally made from low or medium carbon steel. The short neck of these bolts makes them suitable for use with sheet metal, as a standard size neck can create an obstruction.
3. Flat Head, Square Neck: As the name suggests, they feature a flat head, which gives a lower profile on the top or front side of fastening as compared to that of a round head bolt. These types of coach fasteners are specifically designed for the garage door industry. However, they can also be used for other applications.
4. Fin Neck: The fin neck carriage fasteners are most commonly made from low carbon steel material. These fasteners feature a round head and a flat bearing surface. The bearing surface of these bolts makes a 90° angle with the shank. The fin neck bolts are mainly used in thin plywood.
