Or failing that, assemble it with Loctite 603 or similar, super strong, and clock it to an eye-pleasing position. With such a large thread (48 mm), no way a mere human can break that Loctite. Also it's fail-safe, because if the loctite did break, all that would happen is the chainwheel would thread a little further on before stopping when It was fully threaded on against the shoulder. Worst-case scenario is it would look like it does now, which ain't all that bad.
