Abstract

Tornillo de cabeza ranurada con una depresión central dotada de un fondo de forma troncocónica y preferiblemente cuatro hendiduras que parten radialmente de la misma y que están desplazadas en 90 grados una con respecto a otra, cuya pared exterior es parte de un tronco de cono invertido que está dispuesto coaxialmente con el eje del tornillo y cuya superficie de base esta situada sobre la superficie de la cabeza del tornillo, caracterizado porque la depresión central presenta por encima del fondo de la misma un tramo de guía cilíndrico conformado sin arranque de virutas, cuya superficie de sección transversal de forma circular coincide con la superficie de cabeza del tronco de cono asociado a las hendiduras.
