Screwdriver

A hand tool, typically with a handle and a hardened steel shaft with a shaped tip (such as a flathead or Phillips head), designed to turn screws. Screwdrivers are used for inserting and removing screws, enabling the fastening and unfastening of various components in construction, repair, and assembly. They come in a wide variety of sizes, tip types, and handle designs, catering to different screw sizes and application requirements. Modern screwdrivers can also incorporate ratchet mechanisms for increased efficiency or be powered by electricity or compressed air.
