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).

Are you sure it is metric and not a fine thread? ¼” - 28 thread is very close to M10.

Anything made outside of U.S.A. should be metric. Have you tried just using a tap and die to clean the threads?

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 asked because I've gone the M10/1/4"-28 hole a couple of time.

Have you tried RigRite?
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.

Is the one from e-rigging above inappropriate?
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.
