Ikea eccentric screws and Ikea Pax

Hello,
I am currently assembling the Pax and have a question regarding the eccentric screws 113434. I have the problem that the eccentric catches the pin and pulls the boards together, but the eccentric screw (the small round one with and -) does not sit tightly within the recess. I can turn it back relatively easily. From what I remember it used to be different; these eccentric screws always sat very firmly. Or am I mistaken and it is normal that you can turn them back to the left relatively easily, meaning they have some play,

Hello, relatively easy is a relatively individual matter. The eccentrics are not very tight, but also not so loose that you can, for example, easily turn them with your fingernail. In the end, they should click in just a little bit, which you can best feel when you open them again. They can be too loose if the dowel is too long or the hole for the eccentric was drilled with a smaller distance than 34 mm (hole center - board edge).

Hello, thank you for the good answer. I was at Ikea now and it turned out that the recess in the bottom panels was slightly too large, so the eccentric screw did not hold. Problem solved then.
