Patent

CA 2080560

A self-drilling anchor for insertion into a workpiece such as a drywall to secure an element to the workpiece comprises a drilling portion having blade means for drilling a bore of pre-determined diameter into the workpiece, and a threaded portion including a generally cylindrical body of a diameter substantially the same as the diameter of the bore. The body has thread means for tapping into the bore to secure the anchor in the workpiece. The body also has a section having portions of substantially less diameter or lateral extent than the diameter of the bore joining the drilling and threaded portions. The section receives particulate dislodged from the workpiece by the drilling of the bore, thereby preventing accumulation of particulate impeding insertion of the anchor.
