Bolt
Product Introduction
A bolt is a mechanical part, a cylindrical threaded fastener equipped with a nut. A type of fastener consisting of a head and a screw (cylinder with external threads). It needs to be matched with a nut and is used to fasten and connect two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
Bolt is a tool that utilizes the physical and mathematical principles of the object's inclined plane circular rotation and friction to gradually tighten the device. Bolts are indispensable in daily life and in industrial production manufacturing. Bolts are also called the rice of industry. It can be seen that bolts are widely used. The application scope of bolts includes: electronic products, machinery products, digital products, power equipment, and electro mechanical machinery products. Bolts are also used in ships, vehicles, water conservancy projects, and even chemical experiments.
Classification
There are many types of bolts:
Classification by material:
1.Carbon steel bolts
Carbon steel bolts are the most common type of bolts and are made of ordinary carbon structural steel. It has the characteristics of high strength, long service life and low price, and is suitable for general machinery, construction, bridges and other fields.
2.Stainless steel bolts
Stainless steel bolts are corrosion-resistant bolts made of stainless steel. It is suitable for use in chemical, marine, food processing and other environments where corrosion resistance is required.
3.Copper bolts
Copper bolts are bolts made of copper, which have electrical conductivity and corrosion resistance and are suitable for use in power equipment, marine equipment and other occasions.
4.Titanium alloy bolts
Titanium alloy bolts are bolts with high strength and light weight, suitable for aerospace, military and other fields.
Classification by shape:
- Hexagon head bolts
- Round head bolts
- Countersunk head bolts
Characteristics and Advantages
Advantages of bolts
1.Strong load-bearing capacity: Bolts have high strength and can withstand large tensile and shear forces, making them widely used in connecting large machinery and equipment and building structures.
2.Convenient disassembly and assembly: Compared with welding and riveting, the connection and disassembly of bolts is more convenient, does not require special equipment and technology, and will not cause damage to objects.
3.Strong adaptability: Due to the replaceability and adjustability of bolted connections, they can be used to connect parts of different materials, shapes and sizes, and are highly adaptable.
4.High reliability: Bolt connections usually use double-bolt or multi-bolt connections, which ensure the firmness and stability of the connection and are widely used in engineering design and manufacturing.
