Factory disc brake rotor question

Thanks for posting, I'll get some pics later of assembled and disassembled sets. I thought the "swedge" was on the inside, not the outside. Looks like machine/drill marks on inside of stud holes. I'll get better pics.

No way to swedge beneath the head of the stud. Looks like they machined a smooth flat for the head of the stud to sit against.
