Mejoras introducidas en el objeto de la Patente principal Nº. 233.194 por dispositivo de fijación y seguridad para tornillo-tuerca, caracterizadas porque la tuerca estará dentada sólo en la periferia de su parte inferior, estableciéndose una parte cilíndrica interior lisa y plana que apoyará sobre la arandela de sujeción y ésta sobre la pieza base, facilitando así el desmontaje del sistema roscado y dejando suficiente holgura para que descienda la lengüeta de la arandela.
