Which screws for TV wall mount on IKEA BESTA Boas TV wall?

Hello,
in my desperate search on the internet, I came across this forum and hope that a solution to my problem can still be found today (on Sunday) – because I am stuck with the assembly.

I bought a Besta Boas TV wall with a Uppleva Ormo TV wall mount.
Although I had asked if all the screws were included, it became clear to me during assembly that screws are once again missing to attach the part to the back panel of Besta Boas.

WHICH screws, size/length do I now need to finally securely attach my TV with the wall mount?

I have a mixed selection of screws in my cabinets, including SPAX 4*35, and would possibly just take 5 or 6 of those instead of the 3 according to the instructions, but I am not sure if such a relatively thin screw would hold the weight of the 32" device...

Can you help??

Many thanks in advance,
Mary

Look at page 24 of the Besta Boas assembly instructions. There are two lock screws, body washers, and wing nuts listed there. As seen on page 9, these should also have been included with Besta Boas.

Thank you for the reply. During the day I then also found the solution... But it is also crap that the instructions for mounting the TV are with the shelf and not with the wall bracket (which you have to buy separately).
