ABSTRACT:
A self-drilling anchor installable in a wall by means of a screwdriver, the anchor being adapted to receive a threaded fastener serving to hold a fixture against the wall. The anchor includes an externally-threaded shank section having a head engageable by the screwdriver and a longitudinal bore threadably to receive the fastener. Integral with the shank section and extending axially therefrom is a drill section having at least one cutting member and guide means therefor, whereby as the anchor is turned in to the wall by a screwdriver, the cutting member then bores a round hole therein whose bank is engaged by the guide means to ensure circularity of the hole. And as the anchor continues to turn, the shank section enters and taps the hole until its head engages the outer surface of the wall to complete the anchor installation.
