Phillips screws are a type of fastener characterized by a cross-shaped slot on their heads. This design allows for better grip and torque when using a Phillips screwdriver, which has a corresponding cross-shaped tip. The shape helps prevent the screwdriver from slipping out, making it easier to drive the screw into various materials. Invented in the 1930s by Henry F. Phillips, these screws became popular in manufacturing and construction due to their efficiency. They are commonly used in a wide range of applications, from assembling furniture to securing electronic devices, thanks to their ability to provide a strong hold.
