Drill the hole as big as the butterfly nut, insert the screw into whatever you are hanging, put the butterfly nut on then put the nut through the hole all the way. Pull on the screw end of the molly while screwing it in. Once the butterfly end hits the inside of the hole, you can tighten the screw all the way.
The hole you have to create is huge. I'd opt for a pedestal or table instead.
