Grade 12.9 Metric fasteners are specified with a minimum Yield Strength of 165 000psi and a minium Tensile Strength of 185 000psi.
Just a bit less than ARO 2000 series which are in the 215/220 000psi range so can accpet a bit more preload. Certainly good enough for a stock 911S motor I would think but maybe a bit on the limit for 8000rpm race motors. |
