Adjusting UPVC Door Hinges to Stop Door Catching Post questions and find answers on glazing, double glazing, upvc glazing, conservatory glazing, fixtures and fittings etc....

I have a uPVC back door that is catching on the top 'pin' or whatever it is called. It needs the door raising a couple of mm. I believe the Allen key under the hinge does this, except I have 2 screws under each hinge. See photo. Which do I turn, or both, and which way do I turn them?
