This is generally directed to a set for a drug delivery Device comprising a First threaded Member (50, 50), a Second threaded Member (40, 60) with a longitudinal axis and a thread (61), which has at least two consecutive Sides (62, 63, 64) with Gress It's different.The First threaded Member (50, 50) and the second threaded Member (40, 60) are adapted and arranged to rotate relatively with each other around the longitudinal Axis of the second threaded Member (40, 60) during the operation of the Joint establishment of the first dose, Threaded Member (50 50) that is shifted axially along the second threaded Member (40)60) from an initial position to a final position with regard to the second threaded Member (40, 60) due to the cooperation of the first Mechanical threaded Member (50, 50) with thread (61).According to this, a Fast part (62, 64) of the thread (61), which has Greater Progress than a slow part (63) of the thread (61), includes a multi thread start and the slow part (63) includes least Beginnings that the Fast part (62, 64).The same is also directed to a drug delivery Device for the establishment and provision of various doses, variables by a user, a Medicine, comprising such a set.La presente está dirigida generalmente a un conjunto para un dispositivo de administración de fármacos que comprende un primer miembro roscado (50, 50), un segundo miembro roscado (40, 60) con un eje longitudinal y una rosca (61), que tiene al menos dos partes consecutivas (62, 63, 64) con avances diferentes. El primer miembro roscado (50, 50) y el segundo miembro roscado (40, 60) están adaptados y dispuestos para rotar relativamente entre sí alrededor del eje longitudinal del segundo miembro roscado (40, 60) durante la operación de establecimiento de dosis del conjunto, el primer miembro roscado (50, 50) es desplazado de ese modo axialmente a lo largo del segundo miembro roscado (40, 60) desde una posición inicial a una posición final con respecto al segundo miembro roscado (40,
