Bolt for fastening screws in walls, essentially characterized by the fact that it consists of: a slightly frustoconical piece with a slightly hollow upper part and provided in the lower two-thirds of its length with circular teeth-like cuts of sierra; whose frustoconical piece has a longitudinal groove that divides the lower middle part into two symmetrical parts, and lateral sides, facing and intermediate, framed in slots delimiting them, said lugs being joined at their lower ends to the bases of the grooves by means of easy-breaking weakening points, because those cut in the manner of saw teeth facilitate the penetration of the plug into a previously made hole and because said plug, when inserted by a screw, unfolds its pins as well as the longitudinal halves of the screw. The lower middle part of the whole, and also because sideburns, longitudinal halves and sawtooth-like cuts, prevent unlocking the cleat easily, once this has been inserted by the screw.
