Basic Electrical hand Tools. Hand tools are tools manipulated and operated by our hands without the use of electrical energy. Hand Tools and Their Uses. Screw Drivers. Screw drivers are made out of tools steel hardened and tempered at the tip. They come in various size and shapes, which are used to turn or drive screws with slotted heads.
