Good Torque Wrench?

I seem to have galled the lug threads, and destroyed the lug nuts, on my 5th wheel. I have religiously torqued the nuts to 120 ft- lbs as I was told years ago, but seem to have screwed up anyway. Looks as if I will have to have all 32 lugs repalaced, plus new lug nuts, of course.

Have had a marathon of phone calls dealing with this, but one guy who seemed knowledgeable said I was torquing wrong. He said the torque wrench must be reset to zero after each use, otherwise the actual torque will "creep". He also said torque wrenches must be re-calibrated every couple of years, or the settings become meaningless.

Should this "torqueing" be so complicated? Is there a better wrench than my old "clicker"? Another guy said forget torque wrenches, just tighten with a rachet until you feel resistance, drive 10 miles, and tighten just until you feel resistance, again. I'm beginning to lean his way?
  • I use a Snap-on and it seems to work fine. Have had to replace a couple of studs over the years. They are not hard to do if you are inclined to do so.
  • I have had various torque wrenches over the years from the old beam type to the one I have currently. I have never had any problems with the studs on any of my wheels and never have had it calibrated. Years ago folks used air wrenches to put tires on before disc brakes became standard and problems were not that frequent. But to answer your question directly I am sure you can get state of the art torque wrenches today but in my experiences it really does not matter if it is exactly 120 or 122.5 as long as they are all close. I always torque to 100 foot lbs.
  • A really good torque wrench would be a snap-on, but you probably won't like the price. I use a Chinese one from HF and though it may not be quite as accurate, when I checked it against a known standard it wasn't far off. BTW if your fiver has half inch stud's I believe the proper torque is 100 ft lb.
  • If you have alloy wheels, definitely stick with the torque wrench. If you have steel wheels, not so much.
