Carbon Steel	suitable for ordinary conditions, low cost, and good load-bearing capacity. Heat treatment can be performed as needed to increase strength.
Alloy Steel	usually adds elements such as chromium, nickel, and molybdenum to improve strength and high-temperature resistance, and is mostly used in demanding working environments.
Stainless Steel	has good corrosion resistance and is suitable for humid or chemical environments.
Aluminum alloy	It is lightweight and corrosion-resistant, and is suitable for applications where weight is required.
Melting and casting	Select appropriate metal materials for melting and then cast into the basic shape of the bolt.
Cold forging or hot forging	To improve the density and strength of the material, the initial forming of the bolt is usually cold forging or hot forging.
Cutting	Includes mechanical processing processes such as turning and milling, which are used to form the shape of the screw, thread, and head.
Heat treatment	Improve the mechanical properties of the bolt through quenching, tempering, etc., and improve its strength and durability.
Surface treatment	In order to improve corrosion resistance or appearance, the bolt is often galvanized, sprayed, or other surface treatment processes.
Raw material preparation	Select appropriate metal materials, such as steel or alloy materials, and pass acceptance to ensure qualified quality.
Forming	Use forging and other processes to process metal materials into semi-finished products close to the shape of bolts.
Inspection and packaging	After strict quality inspection, qualified bolts are packaged and prepared for shipment.
Hexagonal bolts	The most common shape, with a hexagonal head, is easy to install and remove with a wrench.
Round head bolts	The head is round and is usually used in places with high visual requirements.
