Socket size for m12 prop bolt?

[Ziggy]

Need to tighten the bolts on my prop coupling (again), so I want to get a nice new tight-fitting socket, and can't remember for certain what size I need to go out & buy! Are the nuts & bolts both 19mm? It's an E28 prop btw, so not necessarily the same as E30 stuff, but I figure an M12 bolt's got to be pretty standard?!

17mm is the one you need

You're sure on that? Definitely for m12 bolts? I think E30 ones are M10...

That says the m12 is a 19mm. dunno if that's the same as the prop bolt and nut. hope it helps.
