Default Advice on a stripped thread

I'm a bit bummed out that the Drouyn (aussie) kit I'm restoring has one stripped thread on a floor tom mount. The mount looks very much like a Ludwig, without the logo. This is not as whacky as it seems, since Drouyn purchased parts from Ludwig and Premier too. The hole spacing is perfect for a Ludwig mount. The kit is probably from about 1966. There are a few Ludwig mounts about - unfortunately the one in the USA on eBay has a very chewed up wing nut. Although I'm thinking it's more than likely it's the same thread as the Drouyn. I'm hopeful if I get a Ludwig mount I could use the Drouyn wing-bolt. Are there any MIJ copies that have the 1 7/8" hole pattern? I have next to zero chance of finding another original, which is sad. What do you think about the thread on the bolt being Ludwig sized? Thanks everyone for your help on this resto.

There is a company (their name escapes me) that makes inserts for repairing stripped threads. They screw in and then use a smaller sized screw for the mounting.

Check you local hardware store.

Heli-coil
I haven't used one myself. You might call a machinist for a quote or advice. Good luck!

This is correct! You can repair, and use the old wingnut!

Thanks for those replies. I'm on to it. I knew about Helicoil from my auto adventures, but never seen it in action. For some reason I thought that it meant moving to a different bolt too. Gosh I'd be happy if I could keep the kit original . . .

The machinist my have to drill the hole slightly larger, but he can insert a helicoil with the same inside thread pitch as your wing screw.

You can buy a small tap at your local hardware/tool store & do this yourself...very quick & very simple. Just my 2 cents.

Hey Mikey - a friend needs a few of those MIJ mounts you mentioned. Do you still have some? Do you know what the hole spacing is? Thanks mate.
