What would be the best way to model a nonlinear bolted gasket connection?

This would be a simulation involving multiple thin sandwiched components with a fully modeled bolt (NOT using built-in bolt connector capability) with no penetration contact specified on the head/shank. I am starting with linear material properties in the non-linear model so as to eliminate any issues I will inevitably run into with non-linear material properties but I am having a really tough time getting the model to converge and i believe it has something to do with the way I am specifying the no penetration contact - i have gotten similar, from very complex to simple models to run in linear static with the same contacts that just refuse to run with the non-linear solver.
