I need a couple metric M10 turnbuckles for my Jeanneau Tonic. All I can find are imperial threads. I only need the body and lower toggle and I'd rather not replace the shrouds so I need M10 threads (lower RH, shroud LH).

Tell me about it.
Time to get hi-tech and invest in a cheap 1/4" - 28 bolt and check out the body thread.
Any suggestions as to who to look at? I've found some EU sites, but search engines are tuned to return mostly US results. I know there is a way to tell Google i only want Canada or EU, but I'd have to look it up.
If you look closely at the first picture, you can see there aren't any threads left to clean up.

I think you'll find that an M6 is approximately 1/4. A M10 is just over 3/8.
I'll email RigRite, I forgot about them.
Thanks.
It might fit. It is a little short and doesn't have toggle ends which means I have to rejigger the toggles. I'm a little concerned about the quality too, $15 seems like it might be too cheap, imperial sized ones run $30-$80 for a 3/8.
Better quality marine turnbuckles have a chrome plated bronze barrel and SS studs. This prevents galling between the SS stud and the barrel.
Of course. I see that now. It doesn't toggle like you need. Aside fromj what dlochner points out.
Oh well.
Another option is to replace the swage ends with sta-lok long stud fittings and go imperial. Saves replacing the wires, but an extra $100 or so.
I'm assuming that was a typo and you meant 3/8-28. 1/4" would just slide through a 10mm female ...
As to the comment on running a tap and die through- I would be hesitant to do that on a structurally loaded fastener. OK using a M10 on a M10 but not to change sizes or thread types. Not sure if that was the intention ...

Mea Culpa, I was focused on the thread, fine vs coarse and really didn't think about size. The last time I dealt with this was with a ¼"-28. The point being, some some metric and some SAE threads can almost fit each other and it is easy to make a mistake. One mechanic made a $7K mistake when he mounted the transmission on my engine using SAE bolts when they were metric threaded. Easy mistake to make, frustrating when you forget that SAE have fine and coarse threading.
In my defense, I was somewhat preoccupied wishing the wind to shift 20° to the right so I could sail and not motor 37 miles.
