I thought it was M8 fine simply as the standard M8 bolt I have didnt thread, it started and then stopped. Could have been dirt but felt like a different thread.

In terms of the mounting, yes, its around 22mm. The parker units I was looking at seem to be larger, might need to look at another option. RS Components has a number of actuators, not cheap, but have stock and variety.
