Fitting bed frame, missing parts

[Josie2022]

Hi all,
I'm putting this bed together. I guess there's a missing part here which tightens the screw. Does anyone know what it is and where I can it from in the UK? (Ideally online)
It is 4CM in diameter.
Happy new year to you all.
Thanks in advance.

You need a half moon bed washer and then a nut to go on the end to tighten it. Probably M8.

Aaah, that's brilliant. Thank you so much for taking the time to answer me : )

you seem to be missing the 2 or possibly 3 probably 10mm locating dowels as that rail is twisted
you need at least one to stop the rail rotating
