Carriage Bolts

Carriage Bolts

When you need a strong, secure fastening with a clean, finished appearance, carriage bolts are a dependable choice for the trade. Designed with a smooth, domed head and square neck beneath, they provide a neat look while preventing rotation during installation.

Carriage bolts are commonly used for timber-to-timber and timber-to-metal applications, making them ideal for fencing, decking, garden structures, gates, play equipment and general construction projects. The square section under the head grips into timber as the nut is tightened, allowing for easy installation from one side without the bolt spinning.

These bolts are widely used by builders, landscapers and joiners where both strength and presentation matter. The domed head gives a tidy, low-profile finish, making carriage bolts suitable for visible applications where appearance is important.

Available in a range of sizes and finishes, carriage bolts can be matched to suit internal or external use, depending on the specification. Choosing the correct size and corrosion resistance ensures a secure, long-lasting fixing in demanding environments.

For strong, reliable connections with a clean finish, carriage bolts are a practical and versatile fastening solution. Keep the right sizes in stock and tackle structural timber jobs with confidence.
