Did you know there are more than 100 different types of screwdrivers. The most popular screwdriver is the Phillips screwdriver. The Phillips screwdriver is used to set a screw with a crossed grooved head. Henry F. Phillips invented both the screw and the driver that bear his name. The Oregon businessman patented two versions of a fastening device for crosshead screws in 1934 and 1936. Phillips intended the screw for use with automatic screwdrivers and marketed it for mass-production industries such as auto manufacturing.
