The screw is a tool for fastening the parts of the object step by utilizing the physics and mathematical principles of the inclined circular rotation and friction of the object. Screws are a common term for fasteners, a common spoken word. The screw is an indispensable industrial necessity in daily life, such as a tiny screw used by cameras, glasses, clocks, electronics and the like; general screws for televisions, electric appliances, musical instruments, furniture, and the like; large screws and nuts are used for engineering, buildings and bridges; transportation equipment, airplanes, electric cars, automobiles, and the like are used with screws of different sizes. The screw has an important task in industry, and as long as there is industry on earth, the function of the screw is always important. The screw is a common invention in production and life of people for thousands of years, and is the first invention of human according to the application field.
The screw is mainly used for connecting two workpieces together and has the fastening function. The first person describing a spiral is Greek scientist Archimedes (approximately 287 b.c. -212 b.c.). An archimedes screw is a giant helix contained within a wooden cylinder to lift water from one level to another for field irrigation. The true inventor may not be Archimedes himself. Perhaps he just described something already existing. It was designed by skillful artisans who were not ancient egypt to irrigate both banks of the nile river.
During the middle ages, carpenters used wooden nails or metal nails to connect furniture to wooden structures. During the 16 s time, nailers began producing nails with spiral threads that could more securely attach things. That is a small step from the nail to the screw.
The screw is mainly used for connecting two workpieces together to play a role of fastening, and is used on common equipment, such as mobile phones, computers, automobiles, bicycles, various machine tools and equipment, and almost all machines. The screw is an indispensable industrial necessity in daily life, such as a tiny screw used by cameras, glasses, clocks, electronics and the like; general screws for televisions, electric appliances, musical instruments, furniture, and the like.
