Can anyone identify this screw for me?

We bought a second hand bed but some items are missing. I will email the company, but I was wondering if this is a standard part I could buy at a hardware store. Part K on this image. Diameter 16mm.

Maybe a cone point grub screw?

Brilliant, yes thank you I think so.

Another question - we could do with some of those metal cylinder things that you insert in a hole in the wood and then screw a screw through at a right angle.

What are those called?

I think in your second question, you are talking about a cam lock screw.

No, just image searched that, that's not the right thing. That's quite short and wide whereas what I'm thinking of is a longer, narrower cylinder.

I can probably draw a diagram :o

Sometimes they have a slot or cross on top to put a screwdriver in.

the nuts with the holes are Barrel Nuts I think.

yes, or cross dowels...

I googled barrel nuts and they came up with the cross dowels that look exactly the same

Yes that looks like the right thing. Thank you so much! I don't know why they don't just say this on the parts list instead of unhelpfully calling them "k" and "m".

Bolt and barrel nut?

Doh should refresh!

Seems like two names for the same thing. Doesn't matter - as long as I can google it and see if it can be ordered online. Hardware stores closed where we are :(
