what size socket for my nuts?

anyone know what size socket do i need for the hub locknut - will a 2 " fit?

I measured it at just over 51mm (not quite 52mm) - a 2" is 50.8mm. or do i need to purchase "special" hub socket from paddocks or the like?

torque setting is 65nm and i was wanting to be precise when doing it up

52mm is correct
