Its bigger than an inch, but not on tight. I think i just used an adjustable to remove it. It's torque rating is in inch-pounds I beleive.
When i used to have 4-lug, i used to install by hand tightening the nut while turning the rotor, and then maybe 1/8" more. I know not technically right, but i put a lot of miles on this setup like that.
edit: this is the 4-lug stock setup in taking sbout and not SN95 spindkes
