Holding hex stock in a 3 jaw chuck is one of the easiest things that you will ever do, the chances of spinning that are roughly zero (-:I see what you mean, but if the radius of curvature of the workpiece exceeds that of the bite only those inner two corners will make contact. Think about gripping hex stock with those jaws.
