Abstract
An expansion anchor includes a screw and an anchor body configured to receive a shank of the screw, the anchor body including: a flange configured to be directed towards the screw head; a nut-forming portion configured to cooperate with the screw thread; and a deformable expansion portion between the flange and the nut-forming portion. The nut-forming portion is configured to advance in the direction of the flange, by deforming the expansion portion to a deployed state, by screwing the screw in the nut-forming portion. When the anchor is mounted inside a hole in a wall, with the flange bearing against a first face of the wall, the expansion portion in the deployed state forms a continuous contact surface facing a second face of the wall and has a load-bearing section, transversely with respect to the screw axis, which is generally decreasing from the contact surface towards the nut-forming portion.
