Normally if your assembled parts are modeled whit shell elements and you want stress in your screw you can use beams (with the section properties like your screw) as for bolts or rivets. In the hole you must build a spider.

Hope this help

If you are using a solid model, one can use artifical low temperature to create desired tension preload in the bolt/screw.
