Hmmm... DIN or ISO?

Take a magnet to the studs............don't think they are aluminum?
It takes more torque to move a previously torqued nut than it took to torque it to whatever torque it was torqued to. That's why procedures for re-torquing cylinder head bolts/nuts call for loosening them first, then torquing them again to the proper spec.Update# 2
I just checked my two torque wrenches against one another. I set 600 inch lbs on my small breaker bar and 50 ft lbs on my large (on my car's lug nuts) the larger bar did not move the lug nut at all. So I can assume that they are both set the same, and I assume they are set correctly.
They are original parts, that sprocket had never come off before.
Ok then.........who wants to a take a known good quality, recently calibrated torque wrench and tighten their sprocket fasteners to 80 ftlbs and see what happens ????????? We do know the break away torque has been measured at least once at about 65 ftlbs.
As a couple more data points Honda auto lugs note with 10mm studs are torqued to 80 ftlbs and 12mm studs are torqued to 94 ftlbs. So the numbers are NOT crazy out of the range depending ( of course) on the grade of the fasteners.
So the steel threads stripped from trying to torque the nut, not the threads in the aluminum (which is what I thought happened)?; that is actually good news then; way less damage than I thought had happened. Would run a thread chaser in and out of the hub/carrier anyway if you have one, and put new ones in with some lock-tite. I'm in the 60 ft-lb camp at this point, with lock-tite (for the nuts that is).
"If the Honda ape that normally tightens oil filters has been at it again, the initial torquing to the manual's spec may have actually weakened the metal such that the next time you torque it that high, snap."
Not to derail the sprocket torque thread.......
The oil filter is very likely not over torqued from the factory.........but.........the gasket sticktion more or less sticks the filter in place after a few heat and cool cycles. This a common occurrence and not limited to the NC or Honda in general. The gasket sticks on many vehicle and the technician must be careful not to double gasket the filter if the gasket sticks to the block. Many of the new filters actually crimp the gasket to the filter to avoid the chance it sticks to the block.
