Hi Kip,
This nut requires a socket that is a 2 and 13/64 socket. It is 8 sided
not 6 sided. You can get it here, part # BCS T12, but they want $65 for
it. It DOES have a nice square cut end with no entry taper & fits very well.

Maybe you can borrow one somewhere. Other 12 point sockets of strange
sizes will get a partial grip on the nut. Even a pipe wrench. You can
sometimes get the nut off with a makeshift tool but the nut is quite
thin & should be put back very tight, about 80 - 100 ft-lb. You only get
a couple of chances before ruining a very expensive nut so the correct
socket is very helpful when tightening the nut.
There is a spacer ring between the bearing & the outer flange. The ring
protrusion beyond the flange, with gasket installed, is speced at .001"
to .004". The pressure of the flange on the ring, when the lug nuts are
fully torqued, should assure that the bearing is fully seated in the
hub. A typical gasket measures .010" thick uncompressed, & .004" when
compressed. So if the ring sticks out more than .004" the gasket won't
seal. Use Hylomar HPF or equivalent on all gasket surfaces.
The lug nuts must be evenly torqued to 50 ft-lb for a good gasket seal
& to make sure that the flange seals well. It sometimes happens that
these nuts work loose with the result that the splined hub comes loose.
The first sign of this is oil leaking out of the hub flange. The second
sign is a wheel coming off. The original nuts are self locking & not
recommended for reuse. Most people have success with putting red Loctite
on the used nuts.
