Petzl Quark Replacement Bolts?

I'm possibly looking to replace some of the bolts on my quarks. Just had the threads on one fail and I had to drill it out and replace with a new one from Petzl.  Looking at the bolts though they are stamped with 010.9 M and appear to just be 10.9 grade bolts. In future if I want to replace any of them, is it safe to just replace them with any 10.9 bolt with the correct dimensions? I don't know if the bolts they use are any different to these, and I know if I ask them they'll probably say I can't for liability reasons.

I've used stainless M8/10? of the right length from amazon. has to be round head with sunk in hex obviously. I've also used button head bolts to reduce the head width at the front. Check if there M8 or M10 as I cant remember and the length but like this:
