There are many types of screwdriver available and in recent years many specialist drives have been developed such as Tri-wing, Torq-set and Hexalobular however you are unlikely to come across most of the specialist drives unless you are working in very specific industries.
We will concentrate on the three mainstream screwdriver types that are in use for general purpose and in the automotive industry that are slotted, Philips and Pozidriv.
There is a lot of evidence showing that screwdrivers first came into play in the 15th century. The reason we believe that this is the time that they started appearing is because of screws that have been discovered from that time period.
