Abstract

VARILLA FILETEADA, TAL COMO UN TORNILLO, CUYO NUCLEO PRESENTA UN DIAMETRO, COMO MINIMO, SENSIBLEMENTE CONSTANTE Y EL FILETE UN PASO, AL MENOS, TAMBIEN PRACTICAMENTE CONSTANTE, COMO MINIMO EN UNA PARTE DE LA LONGITUD DE DICHA VARILLA, PERMANECIENDO LAS ESPIRAS SEPARADAS A TODO LO LARGO DE LA PARTE FILETEADA DE TAL VARILLA, QUE SE CARACTERIZA POR EL HECHO DE QUE LA SECCION TRANSVERSAL (4) DEL FILETE (3) CRECE DESDE LA PROXIMIDAD DEL EXTREMO DIRIGIDO HACIA ABAJO (5) DE LA ANTEDICHA VARILLA HASTA LA PROXIMIDAD DE SU EXTREMO QUE MIRA HACIA ARRIBA (6).
