What are carriage bolts used for?

In the realm of construction, carpentry, and DIY projects, the humble carriage bolt plays a crucial role, often without much fanfare. Yet, its simplicity belies its significance in securely fastening materials together. Whether you’re constructing a deck, assembling furniture, or working on a structural project, understanding the utility of carriage bolts can greatly enhance your craftsmanship. Let’s delve into what carriage bolts are, their unique features, and the diverse range of applications they serve.

What are Carriage Bolts?

Carriage bolts, also known as coach bolts or round head square neck bolts, are fasteners characterized by their domed heads and square shoulders just beneath the head. The square neck section is designed to prevent the bolt from turning when tightening a nut. This feature makes them ideal for use in applications where one side of the joint can’t be accessed for holding the bolt head, as with traditional hex bolts.

Uses and Applications:

1. Woodworking: Carriage bolts are extensively used in woodworking projects due to their ability to provide strong, secure connections. They are commonly employed in constructing wooden structures such as decks, fences, and playground equipment.

2. Furniture Assembly: When building furniture pieces, especially those requiring disassembly for transportation or storage, carriage bolts are preferred for their ease of assembly and disassembly. They ensure sturdy joints, contributing to the longevity of the furniture.

3. Automotive Industry: In automotive applications, particularly in vintage car restoration, carriage bolts are utilized for their classic appearance and functional reliability. They may be employed in securing various components, including body panels and interior fittings.

4. Infrastructure Projects: Carriage bolts find use in large-scale construction projects such as bridges and buildings. They are instrumental in fastening steel beams, trusses, and other structural elements securely.

5. Playground Equipment: Given their robustness and resistance to loosening, carriage bolts are a popular choice for assembling playground equipment, ensuring safety and durability for children at play.

6. Machinery Assembly: In industrial settings, where machinery components need to be securely fastened to withstand high levels of vibration and stress, carriage bolts serve as reliable connectors.

Benefits of Carriage Bolts:

1. Security: The square neck prevents rotation of the bolt during tightening, providing a secure and stable connection.

2. Aesthetic Appeal: Their distinctive domed heads lend a classic and finished look to projects, making them a preferred choice in various applications where aesthetics matter.

3. Versatility: Carriage bolts are available in a wide range of sizes and materials, making them suitable for diverse applications across industries.

4. Ease of Installation: Their design simplifies installation, requiring only one tool (a wrench or socket) for tightening the nut, as opposed to needing access to both the bolt head and nut.


Despite their unassuming appearance, carriage bolts play a vital role in various industries and DIY projects. Their unique design features, combined with their strength and versatility, make them indispensable fasteners in woodworking, construction, automotive, and other sectors. Understanding the diverse applications and benefits of carriage bolts can empower craftsmen and builders to create sturdy, long-lasting structures and products. Whether you’re constructing a backyard deck or assembling furniture, carriage bolts are sure to be a reliable and essential component of your toolkit.
