I've never owned a torque wrench but plan to get one soon since I'm having all the tires replaced on my fifth wheel. I want to be sure the mechanic torques the lugs to spec since most like to use impact wrenches. Additionally, I want to recheck the torque shortly thereafter, as recommended. I looked at a Craftsman model today and will also check Harbor Freight.
From what I understand, it's best to get a model that
is good for twice the torque you expect to use (IOW, if your lugnuts take 110 lbs it's best to get a torque wrench rated for about 250 lbs). The reason is that they are more accurate if not used towards the end of the scale. (from what I've read).
