Anchor block with bolt prealod questions

Creator

Hi at all, I modeled an anchor block with M24 fixing bolt in foundation. I have some doubts about the friction between the washer and the block ... I see very high actions and I do not see tensions between the two contact surfaces. Do you think I set the contact parameters correctly?

Also if I have hypothetically a preload of 500 N but my bolt region is composed by 126 knots, the specific load in bolt preload must be 500 or 500/126?
