Anyone have the specs of the bolts for cam sprockets? Diameter and length of the shoulder and thread size and length.

They are 8mm x 1.25 flanged 18mm long with a 13mm head. They are unmarked, but high quality, at least grade 8.8 or better. Mine are not shouldered.

Be sure to torque the bejesus out of them (per service manual)- at least two cases of the sprocket rotating on the cam shaft have been reported (mine being one).
