Abstract: A self-drilling wall anchor device comprises a threaded member having a first threaded section and a second threaded section that provide different diameters, and an outer sleeve having a through hole that provides connective first area, second area, and third area. A second area diameter of the second area is larger than a first diameter of the first threaded section but smaller than a second diameter of the second threaded section. A third area diameter of the third area is larger than the second area diameter of the second area. When the first threaded section and the second threaded section cooperate with the outer sleeve for drilling, the second threaded section blocks the second area and the third area. Arms of the outer sleeve warp and curl out of a gypsum object, not into the gypsum object. The present invention reaches a favorable gripping effect and a preferable anti-retracting performance.

Abstract: A self-drilling wall anchor device has a central bolt, an outer sleeve and a drilling head. The central bolt has a bolt body, a head and a connection portion. The bolt body has a first thread formed around the bolt body. The outer sleeve is mounted around the bolt body of the central bolt and has a flange, a second thread, a compressed head and a deformable portion. The flange is radially formed on and extends from the proximal end of the outer sleeve. The second thread is formed around the outer sleeve near the flange. The compressed head is formed on the distal end of the outer sleeve and has a through hole. The through hole is defined through the compressed head and has a diameter larger than that of the connection portion and smaller than that of the first thread.
