A Phillips Head Screw is a type of fastener characterized by a cross-shaped slot on its head. This design allows for better grip and torque when using a matching Phillips screwdriver, making it easier to drive the screw into materials like wood or metal. The cross shape helps prevent the screwdriver from slipping out, which can be a common issue with flat-head screws. Invented in the 1930s by Henry F. Phillips, the Phillips head screw quickly gained popularity in manufacturing and construction. Its design allows for automatic alignment and insertion, making it efficient for assembly lines. Today, Phillips screws are widely used in various applications, from household items to automotive parts.
