Hmnmmmm...not sure that's correct HercMan. They are marked "9.8". When you look up torque specs for an M8X1 9.8 bolt the recommended torque spec is 30 NM. However, these are supposed to be break away bolts in case of an accident and therefore require lower torque settings. That info is from the GM service manual by the way. Also, the bolts are too heavy to be aluminum.
