I told him that the acorn nuts wobble, and questioned him on the 10.9 metric stamped on the stud. I paid an extra 30.00, to have the studs changed to 7/16-20. He said"all our studs are marked with that, and indicate the hardness".

The problem is, i was raised before the metric system, so i can t question him. Does anyone know if in fact 10.9 converts into a rockwell number for hardness.

His lugnuts that i received also wobble on the studs. I ve been a machinist since hs (50years) and never felt a thread do that

Metric 10.9 is roughly equivalent to grade 8 SAE hardware.
If it's chinese, then all bets are off......most of that sh!t is junk...bad threads OD and ID
