Product features

Carriage bolts have been around for centuries. In the early 1800s, they became popular because they were widely used in the construction of carriages and carriage wheels, thus being christened carriage bolts.

Carriage bolts are used to hold together wood with wood, wood with metal and even metal with metal. Their particular shape allows the bolt to be self-locking when placed through a square hole, especially when dealing with metal. Alternatively, it can also be easily placed through a round hole in most kinds of wood, making it a versatile accessory.

Applications

The most common modern applications of carriage bolts are carpentry and wood construction. They are frequently used by homeowners, and also by professional carpenters, for DIY projects, home maintenance and repairs.

Carriage bolts are commonly used because of their ease of use, especially when dealing with wood. Their smooth, dome-shaped heads offer an aesthetic appeal and some amount of safety when used in building wooden decking, decorative fencing, wooden furniture and backyard play equipment. Along with safety, carriage bolts also provide security as they can only be unbolted from one side. They can be used in fixing doors to prevent unscrewing from the wrong side.
