I bought very small brass Hex Head screws. I have looked for these for sometime now. I saw these on TESTED it's a You Tube show with Adam Savage hosting. He was one of the hosts of the show Myth Busters. Adam was interviewing a gentleman by the name of Ryan Nagata. Ryan builds wonderful TV and move props of Ray Guns. Check it out! I plan to use them in other types of models. I have a company that makes model UFO's. Kit Kraft was very fast in shipping my items. The price was great too! I have built this model of the Nazi Bell the German's were working on in WWII. These little bolts will go around the bottom of the bell just like the real one had.
