What tool do I need for this?

[cuppatea]

Hi, can anyone identify what type of key/tool would I need to open this? It is approximately 1cm across but I can work out the exact size - just need to know if there is a name for this specific shape key/tool.

Thank you in advance

I can't make it out, but could it be these?

What are we even looking at here? Has it been pressed on?

No clues or context

It's a lock on something that needs some sort of tool to turn it to open, but I am trying to figure out what tool/key will open it.

If in doubt, sledgehammer.

Possibly Torx socket.

Might it be a starlock washer?

Can you explain a bit more what it is your trying to open? Like give a picture that's not as close.

Nothing will fit through that small hole and allow you to undo that nut, how do you think someone would be able to put the nut there and do it up in the first place?

It's the classic drip feed thread.
