Rotor Screws...Lessons Learned?
The rotor screws also prevent someone from accidentally pushing the brake pistons in.
If you have the wheels off and use the rotor to turn the steering....you can easily put enough pressure on the pad to push the piston in.
I'm sure there are good reasons that Honda put them there. Best to reuse them if you can.

Guess I am unsure why that would matter? Pushing them in is part of replacing brake pads anyways. Or are you thinking of the scenario that someone does it, does not realize it, backs up afterwards and the pedal goes to the floor? Which does happen to some the first time they do a brake pad swap I am sure... I bet a few garage doors have been run into from that lol
What if you're not swapping pads?
Wheels are off...you're doing suspension work. Nothing at all to the brakes...you grab the rotor and use it to turn the steering...

Yeah I got that part. So I am guessing you are saying the concern is that someone does not realize it and backs into something after cause they did not expect them to be compressed? That was what I was asking. That is a reasonable concern I guess. I think mostly it just makes installing rotors and calipers easier. I have had more cars without those screws than with them so am not concerned if they are missing. As someone else stated, if they get to be where I cannot remove them, they get drilled out and never replaced :P

Yep. Unexpected compression.
I'll admit I don't put them back into any car I plan to track enough to keep swapping rotors. I just keep in mind that they're not on. And if I use the rotor to turn the steering as I mentioned above...I give the brakes a quick test before heedlessly driving off.
But I do reinstall the screws on any other car. A tiny dab of anti-seize and a JIS screwdriver make life easier.
Or replace them with M6 flat mount screws that use a torx or allen keying.
I usually take the car for a quick drive and get the brakes hot then hit the screw with some upside down Canned-Air to super cool it. They come out MUCH easier then. You may still need an impact driver if they are old/seized up bad.

Make sure to use Nickel anti seize when using titanium fasteners.

Little late but for anyone else looking for info on this just grind off the screw head and grind the remainder flat against the hub. The screw serves no purpose outside of an assembly line and is a pain in the ass the likes of which I hope to never encounter again.
grind off the head, hammer on rotor u til it bends over the last bit and pops free, grind any remnants of the screw flat against the hub and keep chugging along. I used a dremel for this FYI and it’s all assuming they don’t just turn right out with a screw driver
