For screwing a bolt into to pop the rotor loose when removing.

That's what I figured. Just found it odd that the hole was countersunk, and, no matter how closely I looked at photos in the store, could not see evidence of threads.

A number of Honda/Mazda/other applications still use one or more screws to locate the rotor on the hub. The rotor used in this kit is likely based on (or is) the same as a number of other 4-100 Wilwood applications, so the hole is in place.
