Abstract

Tornillo auto-perforador que presenta una punta de perforación en una extremidad del vástago de tornillo, incluyendo dicha punta un par de acanaladuras que se extienden con ángulos opuestos iguales respecto al eje de dicho tornillo y, que están dispuestas generalmente en lados opuestos del mismo, un par de porciones de lomo que se extienden entre dichas, acanaladuras, cortándose mutuamente dichas porciones de lomo para definir una estrecha punta de cincel, definiendo cada una de dichas acanaladuras un filo de corte y una superficie posterior, teniendo cada acanaladura una configuración compuesta formada por una sección recta que se extiende hacia el exterior a partir del borde externo del vástago y que incluye por lo menos una porción del filo de corte y una sección curva que incluye por lo menos dicha superficie posterior, teniendo dicha sección curva un radio de curvatura sustancialmente uniforme en un plano perpendicular al eje de la acanaladura.
