Anyone know if they are 1 or 1.25 pitch. Also, to verify, they are M8 x 50mm right, grade 12.9 at least?

 

i just went through this ordering bolts for my intake... assuming they use the same pitch throughout most of those type of bolts, the ones that fit the intake were 1.25 Pitch. i found that 1mm thread pitch was classified as "special" and it did not fit when i tried to use them. needless to say i have an entire extra box of 1mm pitch bolts i have no use for..

so yes, they should be 1.25 pitch.
