Abstract
A metal plug with a plug screw in a casing for attachment of articles to penetrable material. The plug screw of the plug serves a dual function; fixing the plug in the material and also permitting the variation of the distance of the articles relative to the penetrable material. The plug screw has a plug-screw head at a back end, a constricted diameter portion designated as an intended breaking point, and a front end coupled to a spreading cone, a spreading head, and a fixing head. The plug is anchored in the penetrable material by means of the spreading head in the following way. First, by turning the plug screw by means of the plug-screw head, the spreading head with spreading jaws is pulled onto the spreading cone and the spreading jaws of the spreading head engage in the penetrable material. By further turning the plug screw, the spreading cone is tensioned in the spreading head and the plug screw is broken at the intended breaking point, severing the screw into a front plug-screw part and a back plug-screw part connected by way of the casing. The front plug-screw part fixes the plug in the penetrable material by means of the spreading jaws of the spreading head. The back plug-screw part provides a variation margin for leveling the attached article to the penetrable material.
