I guess the plastic part thing should have been a clue, but in my ongoing quest to figure out every way you can mess things up, I messed this up. Lacking the magic hand feel, I do use torque wrenches, and since I had a torque specification for the fixing bolt, I grabbed my small click-type torque wrench and gave this a go. At which point faulty tool operation on my part combined with my lack of hand feel (or even ballpark intuitive sense) for what 6-13 inch pounds feels like, and I stripped the bolt.
In a related story, I've got an FSA Gossamer crank with MegaExo bottom bracket that has an aluminum fixing bolt. Somewhere along the line (I think I'm innocent on this point) that got over-tightened and the first time I tried to remove it (quickly loosing my previously claimed innocence) I rounded off the inside flats and had to a screw extractor to get it out.
Hence, I have an uneasy relationship with fixing bolts.
