A plate-shaped fastener is used to secure a member or an instrument to a wall of plasterboard so constructed as to be not accessible to its back. A driving portion with a pointed tip and an extension are integrally formed from a single bendable thin metal plate. A cut is formed in the thin metal plate to form the driving portion and the extension. The driving portion is driven into the wall and pulled back against one side of the wall and the extension is bent and pressed against the other side of the wall to sandwich the wall between the driving portion and the extension. A screw is then driven through the member, extension, wall and the driving portion to secure the member to the wall.
