This is a discussion on Grade 8 VS. class 10.9 bolts in the General Tech and Maintenance forum
I need to get some bolts for my turbo project and i was wondering if Class 10.9(i think thats the number) bolts are equivalent to grade 8 bolts?...

No they are not the same but very simular. Grade 8 is what the SAE came out with and grade 10.9 is the metric version. Grade 8 min tensile strenght is 150K PSI and 10.9 is 142.2K. Also the torque capacity of the grade 8 is higher then its metric conterpart.
