A mechanical device for securing nut is characterized, characterized in that it immobilizes it by means of a bushing whose external shape can be any, but inside it has an orifice whose interior surface must be a regulated surface of revolution to receive a part of a piece that we will call the plug. This hole in the bushing can completely pierce the bushing or not pass through it; in which last case, in the resulting fund, there will be a hole to make way for the bolt, screw or lag screw that is to be used. In its lower face this bushing will carry one or more pivots that prevent an eventual rotational movement of the bushing, which replaces the washer until today used. It will also present one or two holes that go through the bushing at the height that suits in each specific case and whose section can be square, polygonal or cylindrical and placed so that they are housed in the corresponding part of the recess that the plug has for this purpose. it is explained later. Furthermore, externally this bushing can carry, whenever it is considered convenient, a recess or housing for a metal strip that in the form of spring or seal prevents an eventual exit of the pins.
