2013~2016 Does anyone know the rotor bolt thread size for rotor removal?

M8 X 1.25 bolt should be a standard size for those push-off hole on most rotors. For my 1998 Honda CR-V that bolt is on the parts list. I did get a couple whenever I was getting OEM pads or rotors. Luckily in Texas, I have never had the need to use the push-off bolt.

You are assuming the rotor is Mazda stock part and not 3rd party off market, in which case the hole and threads may be different.
