What are the advantages of 12.9 grade high strength screws?

There are also many types of screws, so they are used in different places. In the future, when purchasing, everyone should also make clear their own needs to purchase. It's like saying that this kind of 12.9-grade high-strength screw may not be well understood by most people. Next, the editor will introduce its advantages for everyone. If you are also interested then read on.

Grade 12.9 high-strength screws are also relatively common in life, and their scope of use is also very wide. This 12.9 grade high strength screw is mainly made of SCM435 alloy steel material in production, which has a small tensile strength of 1220Mpa and a hardness of 39 ~ 44HRC.

Domestic mainly for the textile, hydraulic, injection molding, machinery industry in use. According to the items, we can be divided into 12.9-grade external hexagon screws, 12.9-grade hexagon socket head screws, 10.9-grade countersunk head hexagon socket screws, 10.9-grade semicircular head hexagon socket screws, 12.9-grade set screws, 12.9-grade hexagon socket plug screws and other types. So it is also a variety of types, models are not the same, the scope of use is also different.

As a manufacturer, we suggest that you must make it clear to the manufacturer when purchasing. Our good products and services, excellent technology, and good reputation in the industry is the cornerstone of the company's products sold throughout the country. To live up to the trust of every supplier and buyer. Welcome new and old customers friends to visit our company and order products.

After understanding the types of 12.9-grade high-strength screws and their advantages, let's take a look at other basic information. In fact, this 12.9-grade high-strength screw is now a relatively high variety. Because of its high hardness and tensile strength, its Rockwell hardness can reach 39-44, and its tensile strength can reach 1220N/mm2, but because the shapes of the screws are different, the countersunk head hexagon socket head screws and half-round head hexagon socket head screws produced by the same material can only reach a small tensile strength of 10.9.

It can also fully meet the high requirements of special occasions and components of industrial and mining enterprises for fasteners. As a manufacturer, if you want to produce a good 12.9-grade high-strength screw, it mainly depends on three aspects of raw materials, heat treatment, and laboratory. Our products are made through these three methods. If you want to buy or find a manufacturer for long-term cooperation, then this is definitely worthy of your trust and choice. If you have time, you can find out first, and you will feel more at ease in your choice after you finish the investigation.

After the explanation of the above content, we all know the advantages of this 12.9-grade high-strength screw and its type. In the future, if you buy it, you won't be fooled easily. I hope you can have a further understanding of it after reading it. If you need it, please feel free to contact us.
