ASYNCHRONOUS FAN SCREW A0516-14 LEONE

Leone's range of special screws is the result of extensive experience in the manufacture of expansion screws. The range extends from the classic Pagani fan-shaped screw to the Bertoni screw, and includes a kit for constructing the Class II Twin Wing corrector. The special screws are made of biomedical stainless steel with mechanical precision exceeding one-hundredth of a millimeter. The threads are completely free of surface roughness and guarantee great strength, excellent friction, and non-return.
