When screws were invented, the drivers came into existence because the screws needed to be tighten in metal suits as well as war engines. However, now the time has changed and technology has advanced but the logic remained the same and today we make use of screwdrivers to tighten the screws in modern industrial equipment and other safety devices. The driver is actually a hand tool that has been used for turning the screws and fastening them into some metal or hard wood. These are made of robust quality steel and the tip remains too hard so that it can get a firm grip over the screw. These are also used for the road traffic safety devices that need to be installed at different locations for the safety of the people.
