Stainless Steel Carriage Bolts are an essential component of any construction, repair, or assembly project. Their unique design and durable construction make them a popular choice for carpenters, builders, and manufacturers worldwide. These bolts are made from high-quality stainless steel, which adds strength, durability and corrosion resistance. They are also quite versatile and can be used for a variety of applications, such as woodwork, metalwork, and automotive.


One of the most significant benefits of using stainless steel carriage bolts is their high resistance to rust, which means they can withstand the test of time, and their aesthetic appeal will remain for years. This property is particularly useful when working with exterior applications that are bound to face the elements.


Stainless steel carriage bolts come in various sizes and dimensions, making them suitable for use in different projects. Carriage bolts typically have a square neck that helps hold the bolt in place while tightening, making installation a breeze. The smooth, round head allows the bolt to sit flush against the surface, giving it a streamlined look. The head itself is designed to contour perfectly with the washers and nuts that are used to secure it.


Another aspect worth noting about stainless steel carriage bolts is their ability to prevent the wood from splitting. They are perfect for building decks, pergolas or constructing any outdoor structure. They are the bolts of choice for such structures as they do not damage the wood, and they can withstand harsh weather conditions.


Another use of stainless steel carriage bolts is in the automotive industry. They are suitable for securing various parts and components such as engines, transmissions, and suspensions. There are various sizes available, making it possible to accommodate any specific automotive project's needs.


In addition to their resistance to rust, stainless steel carriage bolts are also quite strong, able to withstand considerable force and pressure. They are constructed from high-quality materials and therefore can withstand heavy loads and vibration without corroding or breaking down.


One of the most notable features of stainless steel carriage bolts is their elegant appearance. They have a sleek, polished finish that adds a touch of sophistication to any project. When combined with other stainless steel hardware like nuts and washers, they add a professional and polished touch to DIY projects or industrial applications.


In conclusion, stainless steel carriage bolts are a popular choice for builders, manufacturers, and DIY enthusiasts worldwide. Their unique design, strength, durability, and resistance to rust make them a versatile solution for a wide range of projects. Their smooth and sleek design provides an elegant finish, making them perfect for use in decorative applications. Replace your ordinary bolts with stainless steel carriage bolts and elevate your projects to the next level.



Stainless steel carriage bolts, also known as stainless steel round head square neck bolts, have a short square section below the bolt head. The product is made of stainless steel, which has the characteristics of corrosion resistance and rust resistance, so it can be adapted to various outdoor humid environments. In addition, we can also make carriage bolts of other materials according to your actual needs.

Since the head of the carriage bolt is round, there is no design of useful power tools such as cross grooves or hexagon sockets, which can also play a role in preventing theft in the actual connection process. The square neck below the head can be snapped into the slot to prevent the bolt from turning during installation. The bolt can be moved in parallel in the groove, so the range of use is very flexible.
