Wheel Nut Size

[winnie]

I have done a silly thing, after having new tyres put on I asked the fitter to put cable ties on the hub caps but in the boot of the car C5 2001 2ltr estate I used the wheel spanner socket on something else and mixed it up.

can anyone remind me of the size of the socket that will fit the wheel nut, just in case I need to change the wheel.

All the Citroens we have owned used a 17mm AF socket, preferably a 6 point one.
