Coach bolts, also referred to as carriage bolts, are heavy-duty bolts specifically designed to be used in fixing woodworking applications, particularly fastening metal to wood. They are popular choices for environments where tight joints are indispensable. The domed head of carriage bolts is shallow, frequently found in a range of sizes and shapes such as square, circular, and hexagonal. The extended head shape is intended to avoid loosening from one terminal, and it also supports stopping the bolt as it draws with the help of wooden construction.
How Many Types of Coach Bolts are There?
Many different coach bolt types exist; they come up with different specifications and are more suitable for various purposes. Standard types available are countersunk coach bolts and flat head carriage bolts; however, the most frequent carriage bolt types you may work with are given as follows:
- DIN 603 Coach Bolts: This type of bolt is standard and is used with a broad range of fasteners and components. They are used throughout Europe with assured quality, scalability, and easy configuration of different components. These bolts can also be employed with parts that can't support ISO (International Organization for Standardization) or its equivalent. They are frequently used with mushroom-head square neck bolts, representing the bolts corresponding to the DIN metric fixings and fasteners.
- Square Headed Coach Bolts: The coach bolt's square head section ensures that it is configured with the help of a spanner. This allows the user-modified leverage and ensures the installation process is very easy. Their square configuration offers a substantial degree of locking capability. In particular, it is especially to be noted while the bolt is tightened into fragile objects like timber wood. Under the carriage bolt's square head, many square-headed coach bolts have an unthreaded area, offering more strength and being resistant to shear.
Finally, certain coach bolts are designed for outdoor environments and work with pressure-treated timber products. These components have additional corrosion-resistant features to suit their intended configuration environment.
