does anyone know what the stock hardness would be for a factory CV bolt
I know they are pretty hard but don't want to get too hard and then end up with something brittle the 8.8 and 10.9 seem the most common to find available. does anyone know? |

I believe the stock socket head cap screws are 12.9. Heat treated alloy steel
