I actually ended up combining the two ideas - a long bolt with
a piece of metal flashing cut and then wrapped around the
bolt so it acted as a friction pin, an extra pivoting point and
a sacrificial surface to the threads (as well as removing some
slop).  Doug's point is very well taken though and if you have a
bolt with too much threads, ideally you should fill the
extra threads in with something - JB Weld perhaps?

Best!
