Screwing the side panel of IKEA PAX with a rubber lip

Hello,

it's me again with the Pax problem The good piece is assembled so far (thanks to the forum and the PAX entry with the wonderful hint to correctly attach the "A" strips!), now one last problem. It's about screwing on the side strip with a rubber lip to close the gap between the sliding door and the side of the cabinet. This strip is screwed to the door from the inside, see instructions step 37:

My problem is that the screws can only be driven in with quite a bit of force on the one hand, and on the other hand they do not sit completely flush (due to the cylindrical underside of the screw head and the head resting on a part of the frame strip). Is that normal, can someone check on their Pax? I have the feeling that the screws are too big (by the way, I exclude confusion of the screws on my part). By the way: the pre-drilled holes of the side strip with rubber lip fit perfectly on the pre-drilled holes of the frame (see upper photo), and the strip can also be perfectly placed on the frame, so a fundamental assembly error can basically be ruled out.

Hello, it can only be as flush as the plastic strip can conform to the screw head. The stiffness is normal, because the screw has to cut a thread into the sheet metal and the hole is slightly smaller than the core diameter of the screw to prevent it from loosening again. You should use a Pozidrive screwdriver (PZ 2) and not a Phillips. That makes a significant difference.
