Screws are versatile threaded fasteners that cut or form their own internal threads as they are driven into a material. They usually have a pointed tip and a full-length threaded shank, and are available with various drive types (e.g., Phillips, Torx, slotted) and head styles (e.g., flat, pan, round). Screws are ideal for joining materials like wood, metal, plastic, or drywall without the need for a pre-tapped hole. Their self-tapping ability makes them efficient for both light-duty and high-strength applications in manufacturing, electronics, and carpentry.
