I always creep up on these M6's ..... 50, 60, 70, then 80 in/lbs max. When I first got an in/lb torque wrench, I thought it was good to go the full 8 ft/lbs (96 in/lbs). I stripped one. I'm surprised it didn't happen sooner than it did. This was a beam type wrench (XJ's fav but then he still likes stock reg/recs, lol) that didn't exactly point to zero anymore so obviously I was going even more. My wallet taught me a valuable lesson there. Getting it fixed at a shop cost more than the Helicoil kit, which I promptly bought afterwards.
