I've put those
in my cart to replace my rusted ones (waiting to gather all my parts before ordering) .
I'm sure it's ok for the diameter which I measured some time ago, and that's the only ones with that diameter on rockauto.
For the head diameter, there's no mention of it (I didn't extrapolate from the picture).
As for the thread length, I guess I've checked there're long enough.. but may double check.
