I can see in the below picture that the center bolts are threaded 8mm. Not all SE's shipped with this setup. Some, including my own, had these holes bored out to accept a 10mm though bolt. I've opened them up myself on other blocks without too much effort. A pass though 10mm bolt and nut is what I use on my plate to prevent these from shearing off and damaging the case.
