The tip of a Phillips screwdriver features a pointed, cross-shaped configuration that matches the corresponding cross slot in the head of a Phillips screw. This unique shape allows the tool to self-center in the screw recess, providing a more stable and controlled engagement. As the screwdriver turns, the design of the Phillips tip allows for greater torque to be applied than a flathead screwdriver, while also minimizing the risk of the tool slipping out of the screw—a phenomenon known as "cam-out."
