Patents #2,046,837 to 2,046,840) for the American Screw Company of Providence, Rhode Island, Phillips succeeded in bringing the design to industrial manufacturing and promoting its rapid adoption as a machine screw standard.

He later sold it to Henry F. Phillips who formed the Philips Screw Company, giving the screw drive the name it is known by to this day. This … Phillips Screwdriver The Phillips screwdriver is also known as a crosshead, because of its cruciform head; however, superior quality drivers, the tip is somewhat rounded.
