The cone at its end expands as the anchor is screwed in and, by means of the friction on the walls of the drilled hole, it becomes a highly-secure fastening with no resins needed. It has an anti-rotation grooved fastener (red) that maintains the plug in the same position. It can be used on concrete as well as on other base materials of a lower resistance where greater expansion is required. This plug must be used with the 24 diameter anchors (ASM-24, AFM-24)
