Abstract
A self centering and drilling wall anchor having an outwardly threaded cylindrical body with a flanged proximal end and a cutting distal end. The distal end has a pointed tip at the long axis of said anchor and is formed with a flute extending from the pointed tip to and communicating with a through bore in the cylindrical body. The flute is defined at its outer edges by a leading cutting edge and a trailing edge, with the leading cutting edge extending radially and proximally from the pointed tip in a plane in common with the axis of the anchor and diverging from the trailing edge to provide access to the flute and the through bore for receiving material cut from the wall by the leading cutting edge.
