Abstract

A device for the placement of recessed nuts, essentially constituted by a lug, preferably metallic, having, at least, two parallel flat faces, crossed by a passage perpendicular to them, in which there is mounted a rod that forms a hexagonal head with a transverse hole and, in said rod, in the part projecting from the opposite side of the mentioned lug, a metallic sleeve is mounted which is fixed to said lug so that it can not rotate and, at the end of the rod, is mounted to the threaded nut is threaded, between whose extreme recesses, tabs are partially lodged in which the aforementioned sleeve ends, and the assembly thus formed is introduced under light pressure until the block is applied against the wall and fastened tightly, in order that he can neither turn nor separate from the wall; maneuver the rod that understands, so that it turns and, in doing so, as it can not rotate neither the sleeve nor the nut, this one is forced to move axially, with what the tabs that determine the axial cuts of the same, are deformed and they curve towards the outside, nailing themselves to the wall, after which, it is enough to let go of the plug and unscrew the threaded rod, which will be separated from the nut, with what will remain, in this form, embedded in the reference hole.
