Common stainless screws are generally not as strong as common steel so
perhaps steel might be a better choice for brake attachment. I think
I'd just use the steel bolts with a bit of anti-seize which would
insulate them from the aluminum and prevent galvanic corrosion (which
I think that you are worrying about).


I use LiquiMoly mounting paste. It doesn't help locking but prevents
seizing and allows quick adjustments or, as has happened, disconnecting
them after a brake failure (had to pussyfoot it home).

Actually anything that tends to insulate the screw from the base metal
will limit or prevent galvanic corrosion - I even used the silicon
goop that is used to stop leaks around window frames and two years
later found no corrosion :-)


I found that the screws through the 7" extender that was factory mounted
were threaded all the way. So I cut those to length and mounted it all.
The bigger rotors feel great, especially on the rear where I went two
sizes up.

Most of the commonly sold smaller sized fasteners are "all thread" as
I suppose that makes them almost universally "all fit" :-) I believe
that some sizes, perhaps 6mm or larger, are also available with an
unthreaded shank.


Typically the top part is unthreaded, maybe because that saves half a
penny in production:

This is the kind of adaptor that was on there until Friday, just not
from Shimano.
