Hi Ji,

What is the contact behavior defined between the screw and the block? Is it frictional contact? To me, it looks like that contact occurs at the edge of the hole and it acts as a stress concentrator. That may explain the significantly large stresses you observe at this location. Please consider watching the video below where the topics of artificially large stresses and how to deal with them are discussed.
