The design of our Carriage Bolt is a perfect blend of functionality and simplicity, making it a popular choice in various fastening applications. The most distinctive feature of the carriage bolt is its rounded, mushroom-shaped head. This head design serves multiple purposes. Firstly, the rounded shape allows for a smooth and flush finish when the bolt is installed, which is aesthetically pleasing and also reduces the risk of snagging or injury from sharp edges. The underside of the head is slightly square or rectangular, which provides a larger surface area for better grip against the material being fastened. This prevents the bolt from rotating when the nut is tightened, ensuring a secure connection.
The shank of the carriage bolt is typically smooth for a certain length near the head, followed by a section of precisely cut threads. The smooth shank acts as a guide during installation, making it easier to insert the bolt through the holes in the materials. The threaded section is designed to engage with the corresponding nut, allowing for a tight and reliable fastening. The length of the shank can vary depending on the specific application requirements, providing flexibility for different thicknesses of materials to be joined.
Our carriage bolts are crafted from high-quality steel, ensuring durability and strength. The surface of the bolt may be treated with finishes such as zinc plating or hot-dip galvanizing to enhance corrosion resistance and prolong the lifespan of the bolt.
1. Secure Fastening: The combination of the rounded head and the square or rectangular underside provides a secure fastening mechanism. As the nut is tightened, the head digs into the material slightly, preventing it from rotating. This ensures that the bolt remains in place, even under conditions of vibration or stress.
2. Easy Installation: The smooth shank of the carriage bolt simplifies the installation process. It can be easily inserted through pre-drilled holes, and then the nut can be tightened using standard tools. The design also allows for quick and efficient installation, reducing the time and effort required for assembly.
3. Corrosion Resistance: With the application of corrosion-resistant finishes like zinc plating or hot-dip galvanizing, our carriage bolts can withstand exposure to the elements. This makes them suitable for both indoor and outdoor applications, such as in construction, furniture making, and automotive repairs.
4. Versatile Sizing: We offer a wide range of sizes for our carriage bolts, including different diameters and lengths. This versatility enables our customers to find the perfect bolt for their specific needs, whether it's for a small-scale DIY project or a large industrial application.
5. Aesthetically Pleasing: The rounded head of the carriage bolt gives a clean and professional look to the finished assembly. It is often used in applications where appearance matters, such as in decorative furniture or architectural projects.

1. Furniture Manufacturing: Carriage bolts are extensively used in furniture making. They are ideal for joining wooden components, such as legs, frames, and panels. The smooth finish of the head and the secure fastening ensure that the furniture is not only sturdy but also looks good. For example, in the construction of tables, chairs, and cabinets, carriage bolts provide a reliable connection while maintaining an aesthetic appeal.
2. Construction Industry: In construction, carriage bolts are used for various purposes. They can be used to attach metal or wooden brackets, braces, and other structural elements. Their corrosion resistance makes them suitable for outdoor construction projects, such as decks, fences, and pergolas. They can also be used in the assembly of prefabricated buildings, providing a strong and durable connection between different parts.
3. Automotive and Machinery Repairs: Carriage bolts find application in automotive and machinery repairs. They can be used to fasten components such as engine mounts, brackets, and guards. The secure fastening and the ability to withstand vibrations make them a reliable choice in these demanding environments.
4. Agricultural Equipment: In the agricultural sector, carriage bolts are used to assemble and repair farm equipment. They are suitable for joining metal and wooden parts of tractors, plows, and other machinery. Their durability and resistance to the harsh conditions of the farm ensure that the equipment remains in good working condition.

Q1: How do I prevent the carriage bolt from rotating when tightening the nut?
A: The square or rectangular underside of the carriage bolt head is designed to dig into the material slightly as the nut is tightened, which prevents the bolt from rotating. However, if the material is too soft or smooth, you can use a washer with a square or rectangular hole that matches the shape of the bolt head underside. This will provide additional grip and prevent rotation.
Q2: Can I use carriage bolts in high-vibration applications?
A: Yes, carriage bolts are suitable for high-vibration applications. The design of the bolt, with its secure fastening mechanism, helps to keep the bolt in place even under continuous vibration. However, it is advisable to check the tightness of the nut periodically in such applications to ensure that the connection remains secure.
Q3: What is the maximum load capacity of your carriage bolts?
A: The maximum load capacity of our carriage bolts depends on several factors, including the size (diameter and length) and the material of the bolt. Generally, larger diameter bolts have a higher load capacity. For specific load capacity information for the bolt you are interested in, please refer to our product specifications or contact our technical support team.
Q4: Are your carriage bolts available in different materials?
A: Currently, our carriage bolts are mainly made from high-quality steel. However, we offer different surface treatments such as zinc plating and hot-dip galvanizing to enhance corrosion resistance. If you have specific material requirements, please contact our sales team, and we will try to accommodate your needs or provide suitable alternatives.
