K/H disc brakes - hub replacement - studs

When I'm pressing the rotor onto the hub, I presume I am actually pressing the studs into the rotor and then pressing the studs/rotor (as a unit) into the hub? or is the rotor a "loose" fit?

Are the original studs swedged in place, or can they just be pressed out?
The rotor is just a PUSH fit on the hub. If you get the proper studs, they PRESS in and hold everything together. Don't worry about staking them...not necessary with the correct studs.
