A Carriage Bolt, also known as a coach bolt, is a type of bolt that is widely used in various applications. Here is a detailed introduction:
It typically consists of a cylindrical shank with a smooth, rounded head. The head is often larger in diameter than the shank and has a flat underside. The top of the head may be either flat or slightly domed.
The shank of the carriage bolt is threaded for a certain length, usually starting from the end opposite the head. The threads are designed to engage with a nut or a threaded hole to secure the bolt in place.
Carriage bolts come in a variety of sizes to suit different needs. The diameter of the shank can range from small sizes like 1/4 inch to larger diameters such as 1 inch or more. The length of the bolt also varies, typically from a few inches to over a foot, depending on the specific application.
They are commonly made of steel, which provides good strength and durability. Some carriage bolts may be made of stainless steel to resist corrosion, especially in applications where exposure to moisture or harsh environments is a concern. Other materials like brass or aluminum may be used in specific situations where weight reduction or resistance to certain chemicals is required.
Carriage bolts are frequently used in woodworking applications, such as joining pieces of wood together in furniture making, construction of wooden structures like sheds or decks. The smooth shank and rounded head help prevent damage to the wood, and the large head provides a good bearing surface to distribute the load evenly.
They are also used in some metalworking applications, particularly when a strong and reliable fastening is needed. For example, in the construction of metal frames or in machinery where components need to be securely held together.
In summary, the carriage bolt is a versatile fastener with distinct features that make it suitable for a wide range of applications in both wood and metalworking, providing a reliable and durable means of joining components together.

HAIYAN is a trusted carriage bolt supplier for construction, OEM, and many other industries. Carriage bolts most commonly have a smooth, domed head with a square section underneath that pulls into the material to prevent spinning during installation. This feature allows for the bolt to be self-locking when installed through a square hole in a metal strap, or a round hole in most woods. It can be installed with a spanner or wrench.
