Abstract
A self-drilling anchor including a screw and an anchor body configured to receive a shank of the screw, the anchor body including: a flange at an end oriented toward a head of the screw, a threaded portion, a deformable expansion portion between the flange and the threaded portion, and a rotation locking mechanism preventing rotation of the anchor body relative to the wall. The threaded portion is configured to engage with the screw thread and advance in a direction of the flange, by deforming the expansion portion, when the screw is screwed into the threaded portion. The anchor body further includes a piercing element at the opposite end from the flange, the anchor including a fastening mechanism between the screw and the anchor body, the fastening mechanism being detachable by a torque, applied between the screw and the anchor body, equal to or greater than a predetermined torque.
