Simulating a bolt pulling through a slot Creo 10.0.7.0

The bolt shouldn't need a nut. I'm just pulling against the slot to see if we can simulate the failure.

I can't imagine that would need to create an imaginary nut for this. What is the best way to create a contact and maintain the cool bolt functionality? (without a nut and another imaginary part for the imaginary nut to connect to) The actual assembly does not have a nut at the end of this bolt and I'm not testing the "pull out" of this bolt in the other part - just the failure of the thin area of the slot.
