You have to get that screw out. I've been surprised at how much force was needed to get one of the two to break loose and I'm using the blue loctite. My biggest fear was stripping one of those bolts. Not sure if you can find an "easyout" that small. If all else fails, you'll just have to get new parts. You'll have to get a new center hub, feathering spindle, blade grips, washers and o-rings. The grips are probably junk and so is the feathering spindle, so you are not loosing as much as you would think.
