Wood screws used in carpentry.
Screws are a type of fastener designed to be driven into objects. Most screws consist of a "male" screw thread (external) wrapped around the cylinder. They are inserted into a nut with a "female" screw thread (internal), and are driven in with a drill or screwdriver. Screws have different head styles, which determines their shape, size, and strength, and may also have different drive types, which determines which screwdriver is required to drive them in. Screws are most commonly used in domestic materials, such as doorknobs, power outlets, and electronics, although they see many industrial uses as well.
