The spoke head driver with concave tip fits on all DT Swiss spoke heads and also fits for SAPIM Spokes. The seat of the spoke head in the hub flange can be significantly improved.

After the spokes have been tightend a bit, the spoke heads are hammered gently into the hub using a light hammer (100 g). The back side of the spoke head is slightly pressed into the hub so that an optimal seat for the spoke head is created. After this operation the spoke heads should seat solidly on the hub and should not stick out any more.
