Well, a 12.9 socket head cap screw seems like the best bet, that new zealand site isn't very informative and he's probably selling SHCS's. Yield stress is 60MPa higher on than the minimum tensile stress of the 10.9 bolt but not sure how brittle they are. I would really want to know more abuot the failure mode before I changed anything.
Any update on this? I am searching for a 12.9 bolt with the correct dimensions but so far all the suppliers I tried can't find one.
