In general, bolts and nuts is necessary. So what is the bolts and nuts? Bolt in daily life and industrial production and manufacturing, is little not, bolt, also known as industrial meters. The use of visible bolts widely. Nut is nut and bolt or screw fastening screw together to the function of parts, all production machinery must use a component. Below is what are respectively bolts and nuts?
The application range of bolt are: electronic products, mechanical products, digital products, power equipment, mechanical and electrical machinery products. Vessels, vehicles, water conservancy projects, and even chemical experiment is also useful to bolt. It is more than useful to bolt. The precision bolt used above, such as digital products. DVD, camera, glasses, watches and clocks, electron, etc., using micro bolt; TV, electrical products, instruments, furniture and other general bolt; As to bridge engineering, construction, using a large bolt, nut; Transportation equipment, aircraft, trains, cars, etc for the bolt and size. Bolt bears important tasks in the industry, so long as the earth exist in industry, function of bolts are always important. It's very simple and clear know what bolt and the application of bolt.
Nut is nut, according to different materials, the divided into carbon steel, stainless steel, non-ferrous metals such as copper and so on several big types. Based on attributes mainly has GB (GB), German standard (DIN), international standard (ISO), Japanese standard (JIS), American standard (ASTM/ANSI) and other standards. Nut performance rating label consists of two parts Numbers respectively represent the nominal tensile strength value of nut materials and QuJiang ratio. Nut is closely connected parts machinery and equipment, through the inside of the thread, the same specification nuts and bolts to connect together, for example, the M4 - P0.7 nut only with M4 bolts - P0.7 series connection (in the nut, the M4 refers to the nut inside diameter is about 4 mm, 0.7 refers to the distance between the two thread is 0.7 mm). U.s.-made products are the same, for example, a quarter - 20 nut only with 1/4-20 screw (1/4 refers to the nut inside diameter is 0.25 inches, about 20 every inch, there are 20 teeth). So what is the application of nut and nut will be clear at a glance. Hope to be able to comprehensive and specific to deepen your understanding.
