Looking for a hinge for Ikea Faktum corner cabinet

It is definitely the hinge that connects the two doors. I will try to take a photo and upload it.

so the two pictures are online

You won’t get anything from Ikea for that anymore, and even if they still had hinges in stock in Sweden, you will only find out the spare part number if someone still has a very old assembly manual for the corner cabinet.

Is the distance between the two holes for the screws 45 mm or 52 mm?

The distance is 45 mm!

That's what I thought.

Get yourself:

2 Intermat 9930 TB52
4 spreading sleeves (if necessary, shorten according to the hole depth)
4 pot mounting screws 3.5 x 13
2 cross mounting plates System 9000 with pre-assembled euro screws for 28 mm Lochreihe distance 0 mm, if the pot hole has a distance of 4.5 mm to the edge, with distance 1.5 mm if the distance is only 3 mm.

Thank you very much IKEA expert, I will do that. I will order the material as you described it to me. Just one more question: the online shop you mentioned only has one type of pot mounting screws. Do you mean those that are 4.5 x 13, which I need?
