if you just have the vehicle-toolkit and no torque-wrench,
which is often the case in emergency situations.
how to put on the right torque ?
Go tight! very very tight
And go back over them, as when you do one tight, when you do the next one tight it can make the one you previously did go slack.
if you don't accidents can happen ::)
