1. Full tooth hexagon bolt
Full-tooth hexagonal bolts, as the name suggests, have threads on the entire bolt, which can increase the carrying area of the bolt head and adapt to large loads.Full-tooth hexagonal bolts are mostly used in places that need to withstand large loads, such as bridges, buildings and other structures.
2.Half-tooth hexagon bolt
Semi-threaded hexagonal bolts, also known as semi-threaded hexagonal bolts, are commonly used fasteners and are widely used in various fields such as machinery and equipment, building structures, and vehicle manufacturing.Half-tooth hexagonal bolts have a hexagonal head and threaded rod, which can provide good connection and fixing effect, especially in the case of vibration or the need to prevent loosening.
3. Fine tooth hexagon bolt
Fine-toothed hexagonal bolts, compared with full-toothed hexagonal bolts, have thinner threads and are mostly used in places that require anti-loosening or small loads, such as furniture, small machinery, etc.
The use of hexagonal bolts
1. Construction industry: Hexagonal bolts are widely used in the construction industry because of their large bearing capacity, such as the connection and fixation of beams, columns and other structures in reinforced concrete.
2. Machinery industry: In the machinery industry, hexagonal bolts are used for the assembly and fixing of various equipment, such as machine tools, reducers, etc.At the same time, because of its good anti-loosening properties, it is also used in some parts that need to be anti-loosening.
3. Furniture industry: In the furniture industry, fine-toothed hexagonal bolts are widely used in the assembly and fixing of furniture because of their smaller threads and better anti-loosening properties.
4. Automobile industry: In the automobile industry, hexagonal bolts are also widely used in the assembly and fixing of car bodies, chassis and other parts.
In general, hexagonal bolts are widely used in various industries because of their strong bearing capacity and good anti-loosening performance.In actual use, suitable hexagonal bolts should be selected according to the specific use environment and requirements.About Us
