If you’ve ever undertaken any sort of home repair project, it’s all but assured you have either used or heard the following phrase: “Hand me the Phillips head screwdriver.” This distinction is key, as one cannot rotate a flat-head screw with a cross-patterned Phillips head tool nor use a flat-head driver with a Phillips screw.
But why have two different kinds of screws at all? What benefits does one have over the other? And why do we call the crosshead screw a “Phillips head”?
According to the National Inventors Hall of Fame, the Phillips in Phillips head refers to Henry Phillips, an inventor who undertook a radical rethink of fasteners. In 1933, Phillips obtained the rights to a socket screw invented by John Thompson that had a cross-slotted rather than slit head. To turn the screw, one had to use a tool that resembled an arrow at the end. (This wasn’t entirely a novel concept, as an inventor named John Frearson patented a cruciform screw in the late 1800s.)
Why did Thompson sell the patent? Apparently he had trouble getting manufacturers interested, as they feared such a screw might be damaged during production due to the deep depression needed in the center.
