What Are Carriage Bolts?
Carriage bolts are a type of fastener designed for use in wood or metal where easy assembly and security are priorities. They are characterized by a round, domed head with no external drive, which makes them difficult to remove without access to the nut holding them in place. This feature also gives the bolt a smooth and aesthetically pleasing appearance on the head side.
As a professional fastener supplier, Xinchi Fastener Co., LTD is glad to introduce some key features and typical uses of carriage bolts:
Features of Carriage bolts:
Domed Head: The head is smooth and round, which not only provides a neat finish but also increases safety by eliminating sharp edges.
Square Neck: Right beneath the head, there is a square section (the shank), which fits into a square hole in the material or sinks into the wood as the nut is tightened. This design prevents the bolt from turning during installation, allowing the nut to be tightened from the opposite side.
Threaded Part: The rest of the bolt is threaded, which allows it to be secured with a nut.
Materials of Carriage bolts:
Carriage bolts are made from various materials including steel (which can be plain, zinc-coated, or stainless), brass, and other materials suitable for specific environmental conditions or applications.
Applications of Carriage bolts:
Wood Construction: Commonly used in wooden decks, docks, and outdoor furniture where a smooth bolt head is needed to prevent snagging and enhance appearance.
Metal to Wood: Useful for fastening metal components to wood, such as in gate construction or attaching metal plates to wooden beams.
Flat Surfaces: Ideal for use in applications where a flat or smooth surface is required for safety or aesthetic reasons.
Installation of Carriage bolts:
To install a carriage bolt, a hole is drilled through the materials to be joined, slightly larger than the bolt’s diameter but smaller than the square shank just beneath the head. As the nut is tightened, the square shank gets embedded into the wood (or fits into a square hole in metal), preventing the bolt from turning.
Overall, carriage bolts are valued for their aesthetic appeal, ease of installation, and the security they offer in various woodworking and metal-joining projects.
