The best solution is Heli-Coils (or equal). They are even used in aircraft
They do require special, oversized taps and install tools, but are, IMO,
the only way to go.
Search eBay and contact the sellers if they don't list your size.
> It does not seem Time-Nutty but I need help repairing threads in a

> I recently installed a new ion pump in an EFOS2 Hydrogen maser and two of

> have damaged threads.
> The bolts go in fine but wont tighten and if you wiggle the bolt you can
> pull it out.
> I've looked at the various locktight and permatex stuff but am unsure
> that they will do what I want.
> I'm hoping someone has experience with these and can advise me.
> What I hope will happen with the right product is that I apply it to the
> threads, screw in the bolt until it just contacts the lock washer, wait
> until the goop cures, and then
> tighten until the lock washer is compressed and the bolt is tight.
> Just don't know what product to try! Want to be able to disassemble
> without special tools or heating.
> Any help is appreciated!
