Abstract
Abstract A hole repair device employs a dish shaped resilient member having a centrally disposed threaded opening receiving an elongated thin screw having a pointed end. In use the dish member is compressed and pressed through the hole to be repaired and is thereafter rotated back on the screw until the circumferential portion of the dish shaped member engages a continuous area surrounding the hole to be repaired. A suitable filler such as plaster, cement or putty is then filled into the hole against the dish member and the screw is broken off inside the repaired surface of the wall.
