The Phillips screwdriver is designed to work with the Phillips screw, which was invented by the American Henry F. Phillips, who patented an improved version of the conventional screw with a deep socket and a cruciform slot. Phillips offered his screw to the American Screw Company, and after a successful trial on the 1936 Cadillac, it quickly swept through the American auto industry. With the Industrial Revival at the end of the Great Depression and the upheaval of World War II, the Phillips screw quickly became, and remains, the most popular screw in the world. A main attraction for the screw was that conventional slotted screwdrivers could also be used on them, which was not possible with the P.L. Robertson (with square slot).

A screwdriver is a tool, manual or powered, used for screwing (installing) and unscrewing (removing) screws. A typical simple screwdriver has a handle and a shaft, ending in a tip the user puts into the screw head before turning the handle. The earliest documented screwdrivers were used in the late Middle Ages. They were probably invented in the late 15th century, either in Germany or France.
