Check out some store that carries speciallised fasteners. Ace Hardware comes to mind. I'm thinking of a two-part bolt that consists of an outer barrel with a flat, wide head that has in internal thread. The other part has the same head, with an external thread that runs inside the first part. They usually have slots in the heads for tightening and would be the least conspicuous.
