This is what happens when you blindly use a torque wrench:
Notice how the bottom bolt is tightened further than the top? Whoever assembled this tightened the bottom bolt first, nearly to spec, then tightened the top. The top bolt hit spec much faster than the bottom bolt because the threads weren't aligned due to the lower bolt being over tightened.
The integrity of a bolted joint relies on all the bolts being evenly tensioned at all times so the circumferential pressure on the clamped part is evenly applied. Learn how to tighten bolted assemblies properly if you are going to work on your own bike. If you feel like you aren't able to tighten bolts by feel, or you merely don't want to learn, take it to a shop. If you can't do it by feel, you can't do it by torque wrench either.
