Dry goods sharing, one minute to take you to understand the 12.9 high-strength screws

In large-scale engineering projects such as trams and airport terminals,12.9 grade high strength screwIt has become a good choice; in the construction of high-rise buildings, the use of 12.9-grade high-strength screws can greatly improve the safety and strength of the building. In addition, 12.9-grade high-strength screws are also widely used in petrochemical, energy and communications fields.

Whether it is the development of mechanical production or the continuous expansion of modern fields, 12.9-grade high-strength screws are an essential material. Our research and application of this material also makes China's industrial manufacturing potential continue to increase. Grade 12.9 high-strength screws will bring stronger and better protection for our construction and development in the future.

Grade 12.9 high-strength screw is a very important connection tool, which is widely used in various fields such as wind energy, aerospace, and automobiles. Its strength can reach more than 120kgf/mm², can withstand greater tension, shear, torque and other forms of force, widely used in various fields. Let's take a look at the application of grade 9 high-strength screws.

Wind farm wind turbine blades need to withstand greater wind, in order to ensure safety and stability, must choose high-strength 12.9 grade screws to fix the blade and blade, to ensure that the blade does not fall off, to ensure the normal operation of the fan.

Various connectors in automobiles need to have high tensile and compressive properties. In particular, important components such as the engine and gearbox must be fixed with high-strength screws to ensure that the engine can resist the huge pressure caused by high-speed driving and prevent the parts from loosening and falling off and causing danger.

Shipbuilding needs to withstand the harsh marine environment, so it is important to use safe materials. In order to ensure the safety of the ship, high-strength screws must be used when fixing the motor, blades and other parts to ensure that the ship can withstand strong winds and waves and ensure work safety.

Aerospace manufacturing has very high requirements on the strength and wear resistance of the connector. Therefore, connections in airplanes and other aircraft must be secured with high-strength screws. This can not only ensure flight safety, but also effectively extend the service life of the equipment.

In the machinery manufacturing industry, high-strength screws are usually used to fix parts on machines, especially in the assembly of various heavy machinery and equipment. Such as machine tools, cranes, metallurgical equipment, paper machines, etc., the use of high-strength screws can ensure the stable operation of the machine and improve work efficiency.
