Phillip Head
screwdriver, named after Henry F. Phillips, a
U.S. businessman from Portland, Oregon and
inventor of the Phillips-head screw and
screwdriver. The importance of the crosshead
screw design is its self-centering properties,
useful on automated production lines. The blade
tip is designed on state-of-the-art machinery so
as to yield quality production. Handle design
has been explained earlier.
