Question about Grounding on Metal Box

I recently replaced a receptacle in a metal box. I noticed that box's ground wire is connected to the screw for the internal NM clamps. Is this permitted? I tried to add a green grounding screw to one of the holes, as that's how I've usually seen it done. They were all too large, and the screw wouldn't fit in any of them. What is the best way to fix this, if it can't be attached to the screw for the internal clamps?

Hi, remove the clamp and just use the screw, or put a green ground screw in there if it makes you feel better.
