How is the screw nailed to the wall
First with the diameter of the nail into the half, and then come up with that nail, then screw into the screw
Use a hammer to make a hole in the wall, and then plug a plastic expansion tube, the last screw.
Use a slightly larger nail than the screw into the wall. After unplugging, use plastic expansion bolts and then screw the screws. The disadvantage is that the strength of the cement is different, and some pull the nails will not care when the wall will tear off the hole.
