A screw is a type of self-tapping screw, intended for creating removable joints, especially of soft materials such as wood, plastic or plasterboard. Unlike screws, during assembly, screws cut their own thread in the material by applying pressure during rotation. When we think of a screw, we immediately think of universal wood screws, screws for wooden constructions with a plate head, screws for wood constructions with a countersunk head or structural screws.Screws are also called ground screws, which are already very popular anchoring elements in the ground.
