There are many names for screws, and everyone may have different names. Some people call them screws, some people call them screws, some people call them standard parts, and some people call them fasteners. Although there are so many names, but the meaning is the same, they are all screws. A screw is a generic term for a fastener. The principle of the screw is to use the physical and mathematical principles of the oblique circular rotation of the object and the friction force to gradually tighten the tool of the utensil.

Screws are indispensable in daily life and industrial production. Screws are also known as the rice of industry. It can be seen that the screw is widely used. The scope of application of screws includes: electronic products, mechanical products, digital products, electrical equipment, electromechanical mechanical products. Ships, vehicles, hydraulic engineering, and even chemical experiments also use screws. Anyway, screws are used in many places. Especially the precision screws used in digital products. Miniature screws for DVD, cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; large screws and nuts are used for engineering, construction, and bridges; transportation equipment, aircraft, trams, automobiles and so on, it is necessary to use large and small screws together. Screws have important tasks in industry. As long as there is industry on earth, the function of screws will always be important.

There are many types of screws, whether it is a very small screw for glasses or a large screw for large-scale heavy electrical engineering. The accuracy of screws is usually 6g (class 2, the American standard "IFI" is 2A teeth), and the rough screws used in construction projects are 1g.

The application range of screws is so wide, so the screw market must be relatively large, the demand must be relatively huge, and there must be more screw manufacturers in the screw industry. When purchasing a professional screw purchasing manufacturer, buyers must first understand some professional basic knowledge of screws, such as screw classification standard specifications and American screw specification table.

If we are going to use a screw, the first thing we need to do is to understand the performance of the screw, which is its characteristics, so that we can use the screw in the right place. Because there are many types of screws, among these screws, the performance of each screw is different, so the screws have different uses. In order to avoid our wrong use of screws, we must have a certain understanding of the performance of the screws, so that we can use the screws in the correct place.

First of all, let's take a look at self-tapping screws. For self-tapping screws, the diameter of self-tapping screws is 0.8mm to 12mm. For these types of screws, they generally have high hardness. Self-tapping screws must be screwed into the test, that is, screw the screw into a test plate, and then check whether the hardness of the screw meets the standard. If it does not meet the standard, it needs to be analyzed. Where is the problem? to find a solution.

There is also a drill tail screw. As the name suggests, the tail of the screw is generally in the shape of a drill tail. The hardness of this kind of screw is also very strong. Compared with ordinary screws, not only the ability to maintain is better, but also in terms of connecting objects. The effect is also very firm. For screws with this performance, no auxiliary processing is generally required. You can directly drill a hole on the object to lock the object, which is not only very convenient to use, but also can greatly improve the work efficiency. This kind of drill screw can be said to be the choice of staff in various fields.
