Phillips screws are a type of fastener characterized by a cross-shaped socket on their heads. This design allows for better grip and torque when using a Phillips screwdriver, making them easier to drive into materials compared to flat-head screws. They are commonly used in various applications, from furniture assembly to electronics. The Phillips screw was invented in the 1930s by Henry F. Phillips, who aimed to create a screw that would reduce slippage during installation. Today, they are widely used in construction and manufacturing due to their efficiency and ability to self-center, which simplifies the fastening process.
