Pegler Bulldog TRV Radiator Tail

[blackcab]

Hi

I have got to fit a Pegler Bulldog TRV to a new radiator. Looking at the valve tail, it doesn't have a built in socket for an allen key. Instead it has an (approx) 15mm square nut built in just after the thread.

What tool do I need to use to tighten up the radiator tail please?

Thank you.
