Carriage bolts, also known as coach bolts or round head square neck bolts, are a type of fastener with a distinctive mushroom-shaped head and a square or rectangular neck just below the head. Here are some characteristics of carriage bolts:
Head Shape: Carriage bolts have a rounded, dome-shaped head that protrudes above the surface of the material being fastened. This design provides a decorative appearance and can also serve as a deterrent against tampering or unauthorized removal.
Square Neck: Carriage bolts feature a square or rectangular neck section directly below the head. This neck is designed to fit into a corresponding square or rectangular hole in the material being fastened. The square neck helps prevent the bolt from spinning or rotating during installation.
Threaded Shank: Carriage bolts have a threaded shank that extends from the square neck down to the tip. The threads allow the bolt to be securely tightened into the receiving material, providing a strong and reliable connection.
Smooth Underside: The underside of a carriage bolt’s head is typically smooth and without any sharp edges. This smooth surface helps prevent damage to the material and reduces the risk of injury when the bolt is installed in applications where it may come into contact with people or objects.
Tapered Tip: Carriage bolts often have a slightly tapered tip at the threaded end. This taper makes it easier to insert the bolt into the material during installation and helps guide the bolt into the threaded hole.
Material Options: Carriage bolts are available in a variety of materials to suit different applications. Common materials include steel, stainless steel, and brass, with steel being the most commonly used for general-purpose applications.
Size and Length Variations: Carriage bolts come in various sizes and lengths to accommodate different requirements. The size refers to the diameter of the bolt’s shank, while the length is measured from the underside of the head to the tip.
Securing with Nuts: To fully secure a carriage bolt, a nut is typically used on the threaded end. The square neck of the carriage bolt helps prevent the bolt from turning while the nut is being tightened, making it easier to achieve a secure and stable connection.
Carriage bolts, also known as coach bolts or round head square neck bolts, come in various types to suit different applications. Here are some common types of carriage bolts:
Plain Carriage Bolts: These are standard carriage bolts with a plain, uncoated finish. They are commonly used in applications where corrosion resistance is not a primary concern.
Galvanized Carriage Bolts: These bolts are coated with a layer of zinc to provide enhanced corrosion resistance. Galvanized carriage bolts are commonly used in outdoor or high-moisture environments.
Stainless Steel Carriage Bolts: Stainless steel carriage bolts offer excellent corrosion resistance and are suitable for applications where durability and a clean appearance are important. They are commonly used in marine, food processing, and architectural applications.
Hot-Dipped Galvanized Carriage Bolts: These bolts undergo a hot-dip galvanizing process that provides a thicker and more durable zinc coating compared to standard galvanized bolts. They are ideal for applications exposed to harsh environments or where extended corrosion protection is required.
Grade 5 Carriage Bolts: Grade 5 carriage bolts are made from medium carbon steel and are heat-treated to provide increased strength. They are commonly used in applications where higher tensile strength is required.
Grade 8 Carriage Bolts: These carriage bolts are made from alloy steel and undergo a heat-treating process to achieve exceptional strength. Grade 8 carriage bolts are commonly used in applications where high tensile strength and resistance to shear forces are critical.
Shoulder Carriage Bolts: Shoulder carriage bolts feature an extended shoulder section below the head. This shoulder provides additional bearing surface and can be useful for applications where the bolt needs to align with specific components or act as a pivot point.
Knurled Carriage Bolts: These bolts have a knurled or ridged section below the head, providing improved grip and preventing the bolt from rotating when installed into softer materials.
These are just a few examples of the types of carriage bolts available. The choice of carriage bolt type depends on the specific requirements of the application, including factors such as corrosion resistance, strength, and specialized features.
Carriage bolts, also known as coach bolts or round head square neck bolts, have a wide range of applications across various industries. Here are some common applications of carriage bolts:
Woodworking: Carriage bolts are frequently used in woodworking projects such as furniture construction, cabinetry, and structural framing. Their sturdy construction and ability to securely fasten wood components make them ideal for these applications.
Fencing and Decking: Carriage bolts are commonly used in fence and deck construction. They provide a strong connection between fence posts, rails, and deck boards, ensuring stability and durability in outdoor structures.
Outdoor Structures: Carriage bolts are suitable for assembling outdoor structures like gazebos, pergolas, and playsets. Their corrosion-resistant variants, such as galvanized or stainless steel carriage bolts, are preferred to withstand outdoor elements.
Automotive and Machinery: Carriage bolts are utilized in automotive and machinery assembly, particularly in areas where a strong and secure connection is required. They are often used in engine components, chassis, and equipment manufacturing.
Marine Applications: Due to their corrosion-resistant properties, stainless steel carriage bolts are commonly used in marine applications. They are used for boat building, dock construction, and securing various components in marine environments.
Structural Connections: Carriage bolts play a vital role in structural connections, such as joining beams, posts, and trusses. They provide the necessary strength and stability required for load-bearing structures.
Furniture Assembly: Carriage bolts are widely used in furniture assembly, including bed frames, tables, chairs, and cabinets. Their secure fastening capability ensures the durability and stability of furniture pieces.
Signage and Displays: Carriage bolts are used in the installation of signage, displays, and fixtures. They provide a clean and secure fastening solution while also adding an aesthetic appeal to the overall design.
General Construction: Carriage bolts find applications in general construction projects, including framing, roofing, and structural connections. They are versatile fasteners suitable for a wide range of construction needs.
These are just a few examples of the many applications of carriage bolts. The versatility, strength, and ease of installation make them a popular choice in various industries where secure and reliable fastening is required.

A carriage bolt is a type of fastener that has a domed or countersunk head and a square section beneath the head. It is designed to be used with a corresponding square hole in the material being fastened, preventing the bolt from turning when tightened.
Carriage bolts offer several advantages. They are easy to install, provide a secure and tamper-resistant connection, and are ideal for applications where a smooth and finished appearance is desired. Additionally, their square section beneath the head provides resistance against rotation when tightened.
Carriage bolts are commonly made from various materials, including stainless steel, nickel alloys, duplex steel, copper, brass and many more. The choice of material depends on the specific application requirements such as strength, corrosion resistance, or aesthetic considerations.
Carriage bolts are available in different head styles, including round head and countersunk head. The round head has a domed shape, while the countersunk head is flat and allows for a flush surface when fastened.
The size of a carriage bolt is typically specified by its diameter and length. The diameter is measured across the shank just beneath the head, while the length is measured from the underside of the head to the tip of the bolt.
When installing carriage bolts, it is important to ensure that the square section of the bolt fits snugly into the corresponding square hole. This prevents the bolt from spinning while tightening. Additionally, it is recommended to use washers under the bolt head and nut to distribute the load and prevent damage to the material being fastened.
