Screws are tools that utilize the physics and mathematical principles of circular rotation and friction on inclined planes to progressively secure mechanical components. The term "screw" is a general term for fasteners, commonly used in everyday speech. Screws are an indispensable industrial necessity in daily life: from small screws used in cameras, eyewear, watches, and electronics; to general screws used in televisions, electrical appliances, musical instruments, and furniture; to large screws and nuts for engineering, construction, and bridges; and to a combination of small and large screws for transportation devices, planes, trams, and cars. Screws have been a common invention in people's production and life for thousands of years, and from the perspective of application fields, they represent a major invention of humanity.
