There are two types of screws a cross (+) and a flat screw (–) Generally, we cannot use the flat screw when we have only a cross driver.
This ‘Twin Driver’ can be used for any types of screw without changing.
This is the way crossed with 2 flat drivers. It is designed to use 2 flat drivers at the same time, when using a cross screw. When using a flat screw, a flat driver is used.
