Factory disc brake rotor question

Everything I got is used Rob, no new stuff. I see now the splines run into the hub, stick out if the rotor a tad. I've read several threads about swedging.
Studs slip right into rotor that I sandblasted some. Shoulder I'm pointing at is a nice fit, but no press needed. Now to go into the hubs, I would say I will need a press.
