Mine is marked 7/8 BSF or 3/4 Whit (worth). If your pocket is deep enough, perhaps get a socket with a 3/4" drive and "T" bar to go with it as you do really have to lean on these to get the right torque. Having said that, I use a 1/2" bar with a lump of gas pipe to extend it. You will also need to make / get a bar which will block the hub from turning whilst you do the nut up. Various patterns exist. Now ignore everything I have said and read this instead !!!
