Abstract

La presente invención se refiere a un tornillo de fijación, caracterizado porque comprende: un vástago roscado; una punta formada en un extremo del vástago roscado, para acoplarse con una pieza de trabajo teniendo la punta una superficie troncocónica exterior y una superficie cilíndrica interior; una cavidad formada en la punta entre las superficies exterior e interior, cooperando la cavidad con la superficie troncocónica exterior para formar entre ellas una cuña anular que termina en un borde circular para acoplar la superficie de la pieza de trabajo,, antes del moleteado, definiendo el borde circular un primer plano; y un moleteado circunferencial para acoplar la pieza de trabajo, dicho moleteado circunferencial siendo formado sobre una porción de la superficie troncocónica exterior de la punta que forma una pluralidad de crestas y raíces circunferencialmente espaciadas, que se extienden desde la porción de la superficie troncocónica exterior más alejada del primer plano hacia, pero sin extenderse hasta el borde circular, los extremos terminales de los dientes definen un segundo plano paralelo al primer plano.
