how to stop a motion at a right position and simulate Deformation

I want to build a model to simulate motion of screw. Below Picture shows my Model. The green part is a screw, and the gray part is a solid mass. But now there is a problem about the model, i.e. the screw will across the mass. But in fact this is of course impossible. So how can i set the model, when the head of screw contact of the mass, this motion can stop or only a deformation but not across the mass.
