Then why do you say it this way? It's certainly possible to misinterpret what you said. A hamfist
mechanic will have a 90% chance of damaging cranks or the bolts if you go "very, very tight" and
then turn a quarter turn more.
There is a *right* torque for chainring bolts. It's usually around 25 ft-lbs if I recall. Any
tighter and you damage the cranks.
Also -- note BB creaking is almost never from the crank/bb interface. Most frequently it's from the
BB in the frame -- those threads. Load 'em up with anti-seize or use teflon tape in the threads and
it's likely the noise will go away.
