Step 1 : Introduction to the question " What company gives its name to the cross-shaped (crosshead) screw and screwdriver? "
...
The manufacturing company that gives its name to the cross-shaped (crosshead) screw and screwdriver is Phillips. The Phillips head screwdriver was created and patented by Henry Phillips in the 1930s and was originally used on the 1936 Cadillac. The Phillips screwdriver has a head with pointed edges in the shape of a cross; it fits neatly into the cross slots of a Phillips cross-shaped screw.
The Phillips screw drive (specified as an ANSI Type I Cross Recess) was created by John P. Thompson, who, after failing to interest manufacturers, sold his design to businessman Henry F. Phillips. Phillips is credited with forming a company (Phillips Screw Company), improving the design, and promoting the adoption of his product. The original patent on the item expired in 1966, but the Phillips Screw Company has continued to develop improved designs.
The Phillips screw design was developed as a direct solution to several problems with slotted screws. It addresses questions about increased cam out potential; precise alignment required to avoid slippage and damage to driver, fastener, and adjacent surfaces; and more recent concerns with difficulty driving a screwdriver with powered tools.
