Reisser do stainless screws called Retinox, but they're not twinthread,
probably not cheap either.

I (OP) have some of them, sort of middling prices and they're OK but
not as good as Turbo Ultra in many ways. For a given diameter they
appear very thin and have no sort of rifling/cutting point.

I always prefer to pre-drill a hole. It saves the wood plitting
