الوصف: Screws, nuts, bolts, and washers are common fasteners that work together to join materials: a screw is typically fully threaded with a point, driven into material; a bolt has external threads and a head, pairing with a threaded nut (internal threads) to clamp parts; and a washer (a flat disk) is placed under the head or nut to spread load, reduce friction, and prevent loosening.
