Hexagonal cylindrical head bolts, also known as hexagonal cylindrical head bolts. Its main components include the head, screw, and inner hexagon. The head is usually cylindrical, while the screw is cylindrical or conical. The structure of the inner hexagon is its most prominent feature, as its six edges are parallel and the distance between them is equal, which is also the reason for its name.
The application range of hexagonal cylinder head is very wide, and it is suitable for various mechanical equipment, such as automobiles, electrical appliances, construction and other fields. Due to its unique hexagonal structure, it can achieve a tighter fit, improving the stability and reliability of the connectors. At the same time, it can also withstand large torques and has good anti loosening performance.
1. In the field of automobile manufacturing
The hexagonal cylinder head has been widely used in the field of automotive manufacturing. This form is used for engine bolts, tire bolts, chassis suspension point bolts, etc. in cars. The structure of the hexagonal cylinder head can effectively resist the vibration and impact generated by the vehicle during operation, ensuring the safety and stability of the vehicle during operation.
2. Mechanical equipment field
In the production of mechanical equipment, cylindrical head hexagonal fasteners are also very common. On mechanical equipment such as CNC machine tools, cranes, and steel structures, a large number of cylindrical heads with internal hexagons are required. These fasteners can effectively improve the stability and service life of the equipment, ensuring the normal operation of the mechanical equipment.
