Abstract
Una llave para tuercas y tornillos, caracterizada esencialmente por que el elemento activo de la misma va dotado de un amplio entrante delantero arqueado, que da lugar a cuatro mandíbulas curvadas, dispuestas de una forma regular y simétrica, y separadas entre sí por tres entrantes asimismo curvados, contra los que van a enfrentarse libremente las aristas de las tuercas, cuyas caras planas, están en coincidencia y reciben el esfuerzo de las cúspides de las antedichas mandíbulas.
