The factory bolts are 16mm heads on 3/8-16 NC threads. This seems like a rather small bolt me, even if there are three of them. Also, I don't particularly like the cantilever design of the bracket attached to the engine. There is a lot of leverage applied to those bolts. They stretch (the grade 5's) get loose, and then begin to fatigue from the flexing of the mount.
