Brake Question (Clicking/Grinding Noise)

It took a little while for it to start. It seems to only be on one side.

It makes a slight grinding noise and a click every rotatation. I thought about the rotor being loose. I know one of the lugs is stripped (sams club) where I cannot tighten it too tight. I thought maybe that may have something to do with it…but there are 4 toehr lugs that are tight…and the one that is stripped is still pretty tight…I can put decent pressure before it loosens again.
