Abstract

Tornillo formador de rosca, en que los pasos de rosca enrollados en el vástago en sectores periféricos en forma de líneas, respectivamente de tiras, que transcurren en dirección longitudinal, presentan una mayor altura de perfil que en sectores periféricas vecinos, caracterizado porque el vástago, en toda su longitud, presenta una sección transversal de núcleo circular, porque los sectores periférica en forma de líneas, respectivamente de tiras, que presentan la mayor altura de perfil, están superpuestos a las pasos d rosca, de modo empinado helicoidalmente, transcurriendo rededor del contorno del vástago, y parque la mayor altura de perfil de los pasos de rosca está constituida por rodete o prominencias formados sobre los flancos de rosca y puntas.
