Front caliper bolt - fine spline or coarse spline?

[SugarBear]

Hey there,
I was wondering if anyone can advise off hand if the front brake caliper bolts on a 2011 gx460 are supposed to be fine spline or coarse? We ordered new ones from Napa, thinking a bolt is a bolt, and we could get the project done today. But we got them home& they are coarse spline, but the bolts that were in there are fine spline. So is Napa just wrong, or did someone screw with our caliper mountsat some point?

Thanks in advance!

As a follow up, does anyone know where we can order the right bolts & get them ASAP?
Thanks!

Interesting. Usually they are M12x1.25 fine spline. Maybe someone helicoiled yours and changed it? That would be odd, but not unheard of.

Meant to say thread pitch, not spline! But M12x1.25 is what ours ended up being. For whatever reason, the bolts supplied by Napa are M12x1.5 instead, so they don't fit. P
