Note that these bolts are grade 10.9 steel, not 12.9, the highest strength. I don't know what is the steel grade for the OEM bolts (cap screws). I couldn't find any M10 x 1.25 pitch 80mm shaft grade 12.9 zinc-plated hex bolts. I did not want to use black oxide coated bolts for corrosion reasons. Grade 10.9 steel has an approximately 17% lower yield strength than grade 12.9. But the 80mm shaft gives 50% more thread bite depth than the 75mm OEM bolts, bringing it almost back to the 16mm of bite that the stock configuration has. No one seems to know the torque setting for tightening the OEM bolts, which could give a clue as to their steel grade. With grade 10.9, zinc coated 10mm shaft diameter screw, you should use 45.2 lbs-ft unless the vendor says otherwise.
