UDH requires the correct axle thread pitch, as the hanger threads to a hollow nut, which the axle threads in to.
There's at least two rear axle head styles (flat and conical Syntace x12), and three reasonably common thread pitches. And an even larger number of widths, even just for 12x148.
Front is just as bad.
