Quote--Mike Noc.
Again not good engineering practice to use a ratchet to undo seized or well torqued up bolts either.
Always a risk they can break and let go suddenly, not what you want when you have all your weight on it. By all means use the ratchet after you have loosened the bolt.
My thoughts on it.
If a bolt is super tight as long as you can set the torque wrench to a figure higher than the normal force required to tighten the said bolt nothing will break.---The torque wrench will let you know when to stop pulling by clicking.---However if you try to continue past that point then it's possible to cause all sorts of damage. To you, the bolt and even the torque wrench.-( this paragraph about undoing a seized bolt )
I believe it to be true that a torque wrench ratchet will be designed to work safely up to the wrenches rated capacity. ( I think this was the point that Simon was trying to make. )
