I assume it’s an electric Impact driver, not a torque wrench; unless it allows you to set max torque.
The reason I had different lug nuts for the steel spare was the matting surface on the steel where the lug nut goes was different from the fitting on the alloy wheel, hence the different lug nuts. You’d have to ask the manufacturer if that applies in your case.
Maybe I’m not understanding what you mean by “it’s not going to make good contact with the hub due to the indentation”. The back of both the steel and alloy wheels make contact with the brake drum. The lug nuts are used to secure the wheel against the brake drum. As long as the wheel makes solid contact with the drum, and aligns with the bolt patter, you are fine (I’m leaving wheel offset out of the discussion). The hub goes through the hole in the middle of the wheel, and does not need to make contact with the wheel.
