Be careful of the fasteners you use. While grade 10 bolts have greater tensile strength and hold tighter before stretch brake parts are subject to more torsion (turning) forces and a "high tensile strength" bolt may shatter under extreme torsion rather than bend a bit.
Fasteners used under torsion USUALLY are softer so they don't shatter and allow some movement and return after the torsion forces are removed. Just look at the stock caliper bracket bolts as an example.
Im talking from experience. I dont care what the internet says. Never had any issues, and 2 of my old cars had over 100k of my miles on these bolts.
You have been LUCKY and LOL on the internet try looking up the specs of hardened fasteners and you can see for yourself that it is an issue.
