Anchor bolt, characterized in that it is formed by an expansion screw and an expandable sleeve by the action of a conical portion, which for this purpose has the screw in the joining area between its threaded end that is threaded inside of said sleeve and the shank of the screw, causing the continuous rotation of said screw the opening and expansion of the various sectors in which the sleeve is partially subdivided, by virtue of longitudinal notches that reach more than half its length, which when it is opened by the penetration of the screw, it inserts the edges of its enlarged parts against the cylindrical wall of the drill previously made to contain the bolt, establishing its fixation.
