Abstract

Tornillo para madera del tipo que comprende una espiga provista de una porción terminal apuntada en un extremo y en su otro extremo una cabeza de introducción de diámetro externo superior al de la espiga adyacente caracterizado porque el tornillo se forma de material de alambre de sección poligonal de configuración maciza en toda su longitud que se retuerce alrededor de su eje longitudinal para formar una serie de canales circunferencialmente espaciados e inclinados respecto al eje longitudinal del tornillo y separados entre sí por las esquinas del material de sección poligonal estando provisto el tornillo de un tipo de rosca para madera formada en la parte periférica del material de manera que se extienda también sobre la porción terminal apuntada del tornillo teniendo la citada rosca sus crestas de máxima profundidad radial en posiciones correspondientes a cada una de dichas esquinas donde el diámetro total de la rosca es igual al diámetro exterior del material retorcido antes del fileteado y teniendo sus crestas de rosca de profundidad mínima o nula en posiciones correspondientes a la profundidad máxima de los canales estando escalonadas relativamente las crestas de profundidad mínima o nula de filetes axialmente adyacentes en dirección circunferencial como consecuencia de la disposición inclinada de los canales a fin de proporcionar resistencia con el tornillo totalmente introducido a una carga de retirada axialmente dirigida comparable a la de un tornillo convencional de tamaño total análogo y de paso de rosca similar totalmente introducido en la misma distancia axial en igual material.
