The KILLER anchor is ideal for applications on hollow materials of all kinds as well as on compact materials; in fact, should the materials be solid, the expansion occurs by compression of the same in the hole; in case of hollow materials or interspaces, the screw draws the plug which forms a "knob" within the cavity, ensuring a strong hold.
The edge (collar) on the body of the anchor prevents it to enter inside the hole causing an incorrect expansion and avoids as well any tension on the coating materials.
It is furthermore equipped (the only one in the market) with a threaded end which ensures a screwing without the possibility of rotation in the hole. Finally it has a diametrically opposite cut that ensures an axial guidance for the screw.
