The advantages of grade 12.9 high-strength screws are introduced, come and collect!

12.9 grade high strength screwIt is a screw with superior performance, with high strength and durability. Because of its easy installation and removal, excellent fastening and high durability, high-strength screws are suitable for household appliances, power tools, automobiles and other mechanical equipment, and are also widely used in industrial applications such as aircraft and ships.

1. High strength

Grade 12.9 high-strength screws are made of alloy steel. Its strength is much higher than that of ordinary screws. It has a very high tensile strength. The tensile strength is 1290Mpa. This is a great improvement for ordinary screws. Meet various high-strength requirements.

2. Corrosion resistance

Grade 12.9 high-strength screws are made of high-strength alloy steel, which can be used in a variety of corrosive environments. They have high corrosion resistance, are not easy to be corroded, can be used for a long time, and are not easy to be damaged.

3. Good fastening

Because the 12.9-grade high-strength screws have high tensile strength and better tightness, they can effectively prevent the screws from loosening, provide a more stable connection, and effectively prevent equipment damage.

4. Easy to use

The installation and disassembly of grade 12.9 high-strength screws are very convenient. Ordinary wrenches and screwdrivers can be used without professional tools, which can effectively improve work efficiency and user convenience.

5. Seismic resistance

Grade 12.9 high-strength screws have good shock resistance, which can effectively prevent the equipment from being damaged by external impact. The use of grade 12.9 high-strength screws can better protect the equipment and improve the safety of use.

Grade 12.9 high-strength screws have many advantages, such as high hardness, high strength, strong tensile bending stress, strong impact resistance, high fatigue resistance, strong bearing capacity, etc. Therefore, it can more effectively resist the tensile bending of structural parts Stress and impact force, thereby effectively preventing damage or deformation of structural parts. It can be used in machinery, aviation, shipping, electronics, automobiles, motorcycles and other industries, and can be used for the assembly of some precision instruments to ensure accuracy requirements. However, due to its higher price, installation and disassembly are more complicated than ordinary screws, so cost and operation complexity need to be considered when using it.
