This image is a reply to those who say this item is not fit for 148x12

you don't need to screw all thread in. about 12mm per side is ok.
Well... if you still doubt that 12mm is not enough, for reference, please look at the stem screws, rotors screws, etc, they are usually about 10~12mm long, so I think you already know if 12mm is enough now.
