Yeah, I’ve found they often don’t work all that hot.
I find they work to get the bolt tight enough so that the flange on the outer part grips the ring it is set into, and then I can tighten the bolt the rest of the way without the tool. That is why I’ve never thought to grease the outside, and probably won’t.
