914World.com _ 914World Garage _ bolt hardness question

Posted by: brant Aug 3 2015, 01:28 PM

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'm pretty sure they're 12.9

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