What is the equivalent of "knockdown screw" in UK

[threedee]

Looking to buy some "knockdown screws".
Its a screw with a very wide and shallow pan head with a hex drive in it.

Cant seem to find anything like it. Not even ebay. Maybe because i dont know what theyre called in UK, source of the plans is Canada so i'm sure its all because of naming conventions...

They are called Furniture/Bed Bolt + Barrel/Cross Dowel available from all good DIY shops and handy shed on the internet, I have used these guys they are quite good, I buy biscuits from them as their range is brilliant.
