The two screws provide 2-axis adjustment. When adjusting observe what moves for each screw. On my Redwood one screw changes the gap/spacing of the door outward in inward while the other changes the gap where the two doors meet in the center. I have similar adjustable hinges at home which have three screws so that the in addition to in/out and tilt to gap another screw adjust the vertical spacing of each door. One day at Home Depot I reviewed these type of hinges and was surprised to find that there were different types of adjustments that the 2-screw (two different hinges that looked similar) could make. Could be worth the time to do a dry run on an eye level/easy to work with door. You Tube could also be a source for observing how to adjust these hinges.
