This is the metric equivalent of grade 8. Grade 8 and all of the other "grades" applies to standard thread hardware.
OP it's really up to you, at the end of the day the 10.9 hardware really doesn't cost more than the low quality stuff and well bend rather shear.
With that said I have plenty of "bolt bucket" bolts holding non important parts of my car together.
A good rule of thumb is if you will feel safer by using a high quality bolt rather than a low quality or random bolt for whatever application you're working on it's probably the better choice.
