This batch has been upgraded from the previous OEM spec 10.9 to 12.9 grade and increased Rockwell hardness.
Geomet coated for corrosion resistance.
Available individually.
The 12.9 grade allows the bolts to be torqued to 110 lbs-ft for a huge increase in clamping force. OEM is 69-83 lbs-ft for reference.
Possibly a dumb question - are these reusable at the given torque rating? We all over-torque our stock bolts to keep the clunks away, some/all of us then treat the over-torqued bolts as disposable after one or a few uses. If we keep to 110 lbs-ft, can we get more life out of these?

These will tolerate repeated torque cycles but exactly how many is unknown. Assuming the same torque as you put on the OEM bolt, these will definitely tolerate it better.
