I have a buddy who has a torque wrench that looks IDENTICAL to the one in the pic. He had a problem overtightening bolts that only needed 25lb ft for the reason I stated above. 17 would be much worse to "feel" because at 25 it still does not "click" but you can "feel" when it hits it.
Trick is to do it SLOWLY otherwise it clicks (stupid softly) and you continue tightening.
Other people just do not understand how a torque wrench works. I met a guy who thought the wrench would just stop on its own when desired torque was reached.
