A self-centering wall anchor (10, 100) having an outwardly threaded hollow cylindrical body (101, 111) with a flanged proximal end and a cutting distal end. The hollow cylindrical body diminishes in diameter toward the distal cuting end (20, 110) in the form of a pointed dome with a pointed centering tip (22, 103) at the center axis of the anchor. An inner bore (14 105) , extends continuously from its opening at the proximal end of the anchor along the center axis of the cylindrical body to the centering tip at the distal end where it is partially closed because of the disposition of the centering tip at the center axis.

Why it's free to use
- Filed November 15, 1995 and granted February 1, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 15, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 15, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
