I have seat belt mounts that have stripped threads. I'm wonding if HeliCoil's are strong enough in case of an accident. Logic tells me, yes they would be fine if installed correctly, but my gut is a little more nervous than my head. Can anyone tip the scales one way or the other for me?

IT'S NOT 12MM! It's 11mm, and SAE standard cars are 7/16" fine. Same thread, BTW, and it's been that way from the gitgo. Seems the "governing bodies", whoever THAT is, had their act together, just this once. IF you can find an 11mm or 7/16" helicoil of the correct thread pitch, it would be fine. Helicoils, installed properly, are stronger than the parent metal ever was. Generally, you DO have to consider wall thickness, but in this case, the wall thickness is there. As for Rich's claim the bosses aren't there, I don't recall seeing any Porsche since the 356C that didn't have them under the carpet somewhere. My 65 911 even has the shoulder belt anchors, years before they were standard on Porsches. BTW, in cases like this, I suspect the thread damage was caused by someone trying to install, with force, the wrong hardware. The Cap'n |
