Screws are indispensable industrial necessities in daily life: miniature screws are used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; large screws and screws are used in engineering, construction, and bridges. Caps; transportation equipment, airplanes, trams, cars, etc. are used for large and small screws. 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 miniature screw for glasses or a large screw for large-scale heavy electrical engineering. The accuracy of screws is usually 6g grade (grade 2, the American standard "IFI" is 2A teeth), and the rough screws used in construction projects are 1g grade (grade 3, "IFI" is 1A teeth).
