I was using my 3" deep draw master die set (The pair of steel plates that clamp the disc of metal between during the first draw) but I couldn't find the bolts.  The only ones I could find that were the right diameter and thread were overly long.  

The wonderful feature about this set-up is that, with the bolts sticking out the bottom of the die set,  they automatically center the MDS over the supporting standoff rings, so that the vessel can't accidentally drag or snag  onto an inside surface of the standoff.  One less thing to go wrong, this way!
