Phillips screw
X-slot metal pin
A Phillips screw has a cross-shaped indentation in its head, designed to be driven by a matching Phillips screwdriver.
The design allows the driver to cam out—slip free—under high torque, preventing overtightening.
Hand me a Phillips screw, not a flathead.
Named for businessman Henry Phillips, who popularized the design in the 1930s.
