Screw
A screw is a versatile fastening device with a threaded shaft that allows it to be driven into materials for secure attachment. Screws are commonly made from metal, though plastic and other materials are also used. The threading on the shaft creates a strong grip, making screws ideal for applications where a permanent or semi-permanent hold is needed. They come in various types, sizes, and head shapes, suited to different construction, woodworking, and mechanical tasks.
