What are the advantages of 12.9 grade high strength screws?

12.9 grade high strength screwIt is a screw used for important structural parts. Compared with ordinary screws, it has higher strength and hardness, and can more effectively resist tensile stress and impact force, thereby effectively preventing structural parts from being damaged or deformed.

Grade 12.9 high-strength screws have the advantages of high hardness, high strength, strong tensile bending stress, strong impact resistance, high fatigue resistance, and strong bearing capacity. Its high hardness can effectively prevent the rotation of the screw, so as to better resist the bending stress and impact force of the structural part, and prevent the structural part from being damaged or deformed. In addition, its strength and load-bearing capacity are also very strong, and it can withstand external forces more effectively, making the structural parts less susceptible to damage.

The use of 12.9-grade high-strength screws is very extensive, such as machinery, aviation, shipbuilding, electronics, automobiles, motorcycles and other industries. It is usually used for important structural parts, such as bearing brackets for mechanical structures, automobile engines, etc. In addition, it can also be used for the assembly of some precision instruments to ensure that the requirements can meet the conditions of complex environment and high temperature and high pressure.

The price of 12.9-grade high-strength screws is higher. Compared with ordinary screws, the price will rise a lot, which requires users to consider the purchase cost when using them. In addition, its installation and disassembly are more complicated than ordinary screws. Special tools are required for installation, and it cannot be installed and disassembled multiple times. This is also a disadvantage of it.

There are generally two installation methods for grade 12.9 high-strength screws: one is manual installation, that is, manually, using a specific tool to screw the screw into a specific position; the other is automatic installation, that is, through an automatic device, The screw is screwed into a specific position. However, due to the particularity of 12.9-grade high-strength screws, specific tools, such as screwdrivers, screw screwdrivers, etc., are required for installation. Ordinary tools cannot be used, otherwise the screws will be easily damaged and the use effect will be affected.

There are generally two methods for removing 12.9-grade high-strength screws: one is manual removal, that is, using a specific tool to remove the screws; the other is automatic removal, that is, using an automatic device to remove the screws. Due to the particularity of the 12.9-grade high-strength screw, its disassembly is also more complicated than ordinary screws. Therefore, specific tools are also required for disassembly to ensure the safety and reliability of the screw.
