This has come up before (fine vs coarse threads in Al.) and all I can tell you guys and gals is: coarse threads in aluminum and coarse OR fine threads in steel. Don't think you can fool Mother Nature by screwing in a Heli-Coil (or equivalent) as the insert is installed in fine threads. Look it up for yourselves - fine threads in Al will not react the high loads imposed by the bottoming out hydro cylinder. Take a look at all the tapped holes in your Lycoming (or Continental too, though I'm not as familiar with the Cont.) and where there is any load, they're all coarse.
