Ahh, I admit I was puzzled when you referenced new bolts arriving with rotors. I get it now.
I wouldn't know about such things, I usually buy the cheapest aftermarket parts I can find. Even when they come with fasteners I will only sometimes use them as they're often cheesy looking compared to the Mother Volvo originals.
My knowledge of metric and international fastener standards is severely lacking but presuming that the M12 10.9 screw is roughly equivalent to a 7/16" grade 8 fastener (M12 is a little bigger diameter, same material strength, 150ksi), then each of those screws should be good for about 6 tons. Unlikely that they would be compromised during use or even ham-fisted maintenance.
Have a great day!
