The screw wont go fully to the hole. and the whole thing with blades are not fixed to the helicopter.

Either the fastener is too short , or it is too large in diameter or the hole in the shaft is too small.

I can't see the top of the shaft but there should be either a hole through the shaft or a notch cut into it. If it's a hole then the top rotor head needs to be positioned so the screw can pass through the hole when tightened.
If it is a notch then the head must be positioned so the screw can seat itself in the notch when tightened to keep the head on and make it rotate with the shaft.
