Cot assembly help

[Sazzlepop22]

Hello, I wonder if anyone can help me.
Trying to assemble a Mamas and Papas Rialto cotbed. M&P don't do replacement parts for this model anymore.
Looking to purchase the thing that goes into this hole but don't know what it's called so can't search ebay for it.
Anyone have any ideas?

I have this and are moving soon so have downloaded the manual off their website - might be worth doing the same to see if it's listed?

Here it is

Thanks for trying but no further forward. I still have the paper copy. The hole where the `K' screws go are missing something to catch the screw. Suspect husband has removed them without noticing. Going to ask a man in B&Q what the part is called. Last resort I'll use super glue haha.

Yeah doesn't help it's not called something or shows what size it is!

Mines in storage so can't get it out for a while so can't measure etc for you

I think they're called cam lock nuts.

Oh actually they might not be, as with those you normally have another hole to line it up and can't see from the pic

They cam nuts, you can get them on eBay ! (We had to order some when we lost all of the cot fixings when moving house)

If you Google ‘cot bolts’ they come up

Hi everyone, thanks for your suggestions. The part we needed is called an "M6 insert nut" which cost 2.50 for a bag of fifty from ScrewFix. Just thought I'd update the thread incase anyone in the future has the same issue as me.
