Anybody heard of Grade 10.9? Ace hardware has them, however Ive snapped 2 of them (6-8mm) already.

Im getting ready to change my engine mounts out (10*f outside) and dont want to snap the old bolts on the tranny mount.

When I installed my poly tranny mount, I noticed I could torque one of the bolts on the tranny at 27lbs for about 5 turns, worries me.

Is this 10.9 really SAE grade 5 or something?
