Abstract

Tornillo de cabeza arrancable (1; 1''; 1") con varias secciones roscadas (3; 3''; 3") y una sección de cabeza (5; 5''; 5"), unido con las secciones roscadas (3; 3''; 3") por medio de un punto de rotura controlada (7; 7''; 7"), habiéndose previsto entre las secciones roscadas (3; 3''; 3") otros puntos de rotura controlada (7; 7''; 7") en forma de disminuciones de sección, caracterizado porque por lo menos un punto de rotura controlada escalonado (13; 13''; 13") está constituido de forma que su par de giro de arranque (aNm) es menor que el par del punto de rotura controlada siguiente, más alejado de la sección de cabeza (5; 5''; 5"), y que el par de giro de arranque (aNm+1) del punto de rotura controlada siguiente vuelve a aumentar respecto del par de giro de arranque (aNm) del punto de rotura controlada escalonado (13; 13''; 13"), porque el par de giro de arranque de los puntos de rotura controlada escalonados (9; 9''; 9") aumenta constantemente en las secciones sin punto de rotura controlada escalonado (13; 13''; 13"), en dirección a la sección de cabeza (5; 5''; 5"), y porque en el punto de rotura controlada escalonado (13; 13''; 13") engrana una herramienta distinta que en las secciones roscadas más alejadas de la sección de cabeza (5; 5''; 5").
