Carriage bolts perform well in many applications due to their unique structure and anti-rotation design. Its diverse material selection and surface treatment methods enable it to adapt to different use environments and needs. From a structural point of view, the round head and square neck design are both beautiful and functional; from the perspective of material and surface treatment, different choices can significantly improve the performance and service life of the bolts. Through reasonable material selection and surface treatment, carriage bolts can provide reliable connection solutions under various harsh conditions and are widely used in construction, machinery manufacturing, furniture assembly and other fields.
Structure
Round head
The head of the carriage bolt is round, smooth and without notches. This design makes it more beautiful in appearance and prevents external damage and corrosion.
Square neck
Immediately below the round head is the square neck, which is designed to prevent the bolt from rotating during installation and ensure the stability of the installation.
Threaded rod
The threaded part below the square neck is used to cooperate with the nut to provide a firm connection.
Features
Anti-rotation design
The square neck design allows the carriage bolt to automatically embed into the wood or metal during installation to prevent the bolt from rotating. This is especially useful when single-sided operation is required.
Beautiful and durable
The round head design is not only beautiful, but also reduces wear and corrosion on the exposed part of the head, extending the service life of the bolt.
Easy to install
Installation in wood or metal does not require special tools, is easy to use, and is suitable for various construction environments.
Material
Carbon steel
The most common material, with good strength and economy, suitable for general application scenarios.
Stainless steel
It has excellent corrosion resistance and is suitable for humid or corrosive environments, such as outdoor construction, shipbuilding, etc.
Alloy steel
By adding different alloy elements, the strength, hardness and wear resistance of the bolt are improved, which is suitable for high-strength connection requirements.
Surface treatment
Hot-dip galvanizing
Forming a thick layer of zinc on the surface of the bolt, providing long-term corrosion protection, suitable for outdoor and humid environments.
Electrogalvanizing
Forming a thin layer of zinc on the surface of the bolt by electrochemical method, providing basic corrosion protection, suitable for general indoor environments.
Nickel plating
Improving the corrosion resistance and appearance quality of the bolt, suitable for application scenarios with high requirements for appearance.
Chrome plating
Forming a bright chromium layer on the surface of the bolt, enhancing wear resistance and corrosion resistance, while improving the decorative effect.
Phosphating
A chemical treatment method that forms a corrosion-resistant phosphating film to improve the corrosion resistance and surface hardness of the bolt.
