The Phillips-head ("crosshead") screw and screwdriver are named after its creator Henry F. Phillips .
A Philips head screwdriver, unlike a flat head screwdriver is slightly tapered to the point and has a characteristic + point or nose.Screws with a "Phillips head" have an inverse + profile rather than a single groove of a normal screw.This means that when the screwdriver is inserted into the screw is catches at 4 points (along the +), rather than along a single line. If you add up the surface area of the groove of a Philips screw to a similar (similar size) single groove screw you will notice that is is much larger; this means that the screwdriver has more surface area on the screw head and that it is divided over 4 contact points. This allows the Philips screw to be tightened with more torque than a traditional screw before the head shears off.
