I don't know what the actual answer is, but I say 6 hits without scoring a run is theoretically possible: three hits to load the bases, two fielder's choice outs of the lead runners, then two more singles to load the bases again. Then the 6th hit would be a batted ball into a baserunner. The baserunner would be the 3rd out and the batter is credited with a hit. Or the 6th hit could be, although unlikely, an infield hit where there's an attempted putout at 1st, then the batter rounds 1st in attempt to go to 2nd and is immediately tagged out before the run crosses the plate.
