I'm forseeing the new stem incorrectly installed and thus leaving to a dangerous accident, to themselves and others.
This haphazard is actually common to DIYs as a result of not getting enough torque from silly allen keys of condo tools. Socket wrench is my friend here.
What are you suggesting, that you can't get a quill stem tight enough with a regular allen wrench? That's wrong. You don't actually want to torque it down too tight.
