Probably the only way. Most double flatted nuts, at those torque specs, would need the open end adapter to be made thick enough to use every thousandth of the width of the flats for any life before the nut would be rounded over from the OE adapter wedging itself open. A hex nut, and a box end adapter would be much more practical, but I've not seen those for sale ever, just the OE types. I suppose somebody (typical ID10T) warming a chair would assume we could use a deep socket in that event. If the double flats go all the way to the face of the nut, it shouldn't be that difficult to make a custom box end to fit it.
