Screws, also called "screw" (screw), "screw" (screw). In fact, screws are known generically, and screws and screw rods are different from each other. Screws are generally called wood screws; they have a pointed tip and have a large pitch and are generally used to fasten wooden and plastic parts. The screw rod is a machine screw (mechanical screw). It is a kind of screw with a flat front end. The screw pitch is small and uniform. It is generally used to fasten metal and machine parts.
The type of screw, whether it is a tiny screw used for glasses or a large screw used in large-scale heavy-electric engineering, has many types. The main purpose is to use a high degree of industrial product to form a fixed one, and if it is used, it often occurs between teeth and teeth. , Too hard to lock the screw head off, or bad teeth lock failure to meet the conditions of use, are all quality accuracy problems. Screws are "quantity products" and are not hand-made artworks. In mass production, they are intended to provide consumers with high-precision, stable quality and affordable prices. The precision of the screws is usually 6g (2nd grade, U.S. specification "IFI" is 2A teeth), and the crude screw used in construction projects is 8g (3rd grade, "IFI" is 1A teeth). The value of screws is very important. There are examples in the world of bankruptcies caused by poor screw quality. There are also examples of aircraft falling down and vehicles being subverted due to poor screws.
There are many names for screws. Each person's name may be different. 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, the meanings are the same. They are all screws. Screws are a common term for fasteners. The principle of the screw is to use the physics and mathematics principle of the object's bevel circular rotation and friction to gradually fasten the tools of the artifact mechanism.
Screws are indispensable in everyday life and industrial manufacturing. Screws are also called industrial rice. Visible screws are widely used. The scope of use of screws are: electronic products, mechanical products, digital products, electrical equipment, mechanical and electrical products. Screws are also used in ships, vehicles, water conservancy projects, and even chemical experiments. This also reflects the importance of screws in the industry, such as the use of precision screws on digital products. DVDs, micro screws for cameras, eyeglasses, watches, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; and large screws and nuts for engineering, construction, and bridges; transportation equipment, airplanes, trams, automobiles. And so on for the size and use. Screws have an important task in the industry. As long as there is industry on the earth, the function of screws is always important.
The type of screw, whether it is a small screw used for glasses or a large screw used in large-scale heavy-electric engineering, has many types. The precision of the screw is usually 6g (2nd grade, the American standard "IFI" is 2A teeth), and the rough screw used in construction projects is 1g class.
The scope of application of screws is so wide, so the screw market is certainly relatively large, the demand is certainly relatively large, and there must be more screw manufacturers in the screw industry.
