A Phillips screwdriver is a type of tool designed for driving screws with a cross-shaped (or "+" shaped) socket. It features a pointed tip that fits into the corresponding shape of a Phillips screw, allowing for better grip and torque compared to flat-head screwdrivers. This design helps prevent slipping, making it easier to tighten or loosen screws. Invented by Henry F. Phillips in the 1930s, the Phillips screwdriver has become a standard tool in many households and industries. It is commonly used in assembling furniture, electronics, and various machinery, providing versatility and efficiency in tasks that require fastening.
