If you get a long enough bolt, there is a pretty good unthreaded section on it. They only tend to thread the area likely to have the nut on it, leaving the rest full diameter, at least around here. A 6 inch bolt will probably have 4 1/2 or 5 inches of unthreaded length just below the head. Measure the amount you need unthreaded and go shopping.
