I apologise for being too fussy. I have a syndrome called self preservation. I've noticed Hardly-Worthit drivers don't have this basic human instinct.
Not being too fussy.

Your bolt example is dead-on. However, I can't tell you how many iron, Brembo race rotors I've heard rattle, to include new, out-of-the-box examples. Brake Tech iron rotors do the same. They float freely, without spring washers. IDK, I'm not an engineer. But, I'd think the engineers, who specialize in these components, have a pretty good idea what they're doing. In fact, before floating rotors became mainstream, they didn't have spring washers. When nearly every sportbike started coming with them, people started complaining about the rattling.
