Copper Fastener (3)The drywall screw includes an elongated shaft about an axis, a screw head at one end and threads about the shaft. The screw head has a recess having upper and lower portions. The upper portion is comprised of an upwardly flared thin-walled section having convex and concave interior and exterior surfaces, respectively. The lower portion includes a Phillips head slot for receiving a Phillips head driver. The recess in the head of the drywall screw and the outwardly flared head enables the screw to be driven into the drywall without tearing or loosening the paper overlying the drywall, while simultaneously providing a sufficient recess for receiving the drywall mud finishing compound. In a further form of drywall screw, the upper portion of the screw head is formed by a thin-walled portion defining a conical surface of revolution about the axis of the screw.
