What are the characteristics of 12.9 grade high strength screws

12.9 grade high strength screwIt is a kind of high quality screw, which is famous for its good mechanical properties and is very popular in the application field. After high-precision processing, it has good toughness and high strength, can meet a variety of complex use environment, with corrosion resistance and tensile strength. The main performance feature is strong tensile strength. Its tensile strength is not only higher than ordinary, but also more stable. Its tensile strength is as high as 12.9, which can meet the strict engineering requirements and ensure that there will be no fracture during use, thus ensuring the safety and reliability of use. In addition, it also has the characteristics of strong corrosion resistance. Its surface treatment technology is exquisite, which can effectively resist acid and alkali corrosion, ensure that it will not be corroded during use, thereby improving the service life.

Grade 12.9 high-strength screws have the characteristics of quality assurance. Each one has undergone multiple rounds of testing to ensure surface quality and internal quality, to ensure compliance with various national standards, reliable quality, and can meet various requirements of customers. All in all, it is a kind of screw with good performance, reliability and quality assurance, which can meet various requirements of customers, and is also one of the widely used screws in the market. It is characterized by high strength and high corrosion resistance. It can effectively part of the stiffness, resistance capacity, so as to meet the requirements of engineering applications. Applications and advantages are as follows:

Strength: The strength can reach 1000MPa, which can meet the general engineering requirements;

2, corrosion resistance: the use of special materials, with corrosion resistance, can resist the erosion of most environments;

3, good structural performance: the structural performance is very good, can meet the general engineering requirements;

4 Low cost: The price is very low, which can greatly reduce the cost of installation and maintenance.

Grade 12.9 high-strength screws can be widely used in engineering machinery, automobiles, ships, construction, petroleum, chemical, metallurgy, mining and other industries, and can provide effective help in installation and maintenance. For example, it can be used in the automotive industry for the installation and maintenance of auto parts, and the rigidity of parts; it can also be used in engineering machinery for large-scale machinery and equipment to improve the rigidity and resistance of the equipment.

The advantages of grade 12.9 high-strength screws are mainly as follows:

1. Fast installation: The installation is very fast, which can greatly save the installation time of the project;

2. Convenient maintenance: maintenance is very convenient, parts can be replaced by replacing the wire, no need to reinstall;

3. Low price: The price is very low, which can greatly reduce the cost of installation and maintenance;

Quality: It can meet the requirements of general engineering applications.

Disadvantages of 12.9 grade high strength screws

Technical requirements: technical personnel must have certain skills and cannot be installed by ordinary workers;

2, poor wear resistance: poor wear resistance, may be due to wear and failure;

3, the price is higher: due to the use of special materials, its price is higher, not suitable for ordinary applications.

Requirements for safe use of 12.9 grade high strength screws:

1. Application range: The application range is very wide, but it cannot be used in special environments such as high temperature and humidity;

2, construction technology: by professional and technical personnel to complete, can not be installed by ordinary workers;

3. Installation process: the process is completed according to the prescribed process and cannot be overloaded;

4. Installation and maintenance: regular inspection must be made to find faults in time and deal with them in time.
