Abstract
TORNILLO AUTOCORTANTE CON AL MENOS UNA ROSCA (4) DE UNO O VARIOS HILOS, QUE SE EXTIENDE AL MENOS EN PARTE SOBRE EL ESPARRAGO (1) DEL TORNILLO Y CON UNA CABEZA (2), AL MISMO TIEMPO, QUE EL CANTO (5), QUE FORMA LA ARISTA DE LA ROSCA, ES AL MENOS ONDULADO EN UNA PARTE Y QUE LA ROSCA (4) SE EXTIENDE HASTA EL EXTREMO DE LA PUNTA (3) DEL TORNILLO. LA ARISTA ONDULADA DE LA ROSCA, POSEE EN LA PUNTA (3) DEL TORNILLO MUESCAS (6), QUE INTERRUMPEN LA SUPERFICIE DE LOS FLANCOS. LAS MUESCAS (6) SON ASIMETRICAS, DE FORMA QUE SU SUPERFICIE DE FLANCO (7) DELANTERA EN EL SENTIDO DE ROSCADO ES MAS PENDIENTE QUE LA SUPERFICIE DE FLANCO (8) TRASERA EN EL SENTIDO DE ROSCADO.
