Torque values have gone the way of the dinosaur, and have been for years. Most critical industrial applications use bolt stretch, in the case of stud and nuts, a dial indicator measuring the increased length of the stud. Capscrews, gr 5, gr7, gr8 use a snug fit to remove slack and then an additional 120 degrees of rotation. And so on. Automotive and non critical apps will prolly use the old torque wrench forever. I have one anecdote to share, when working on marine diesels some years ago, we had a schedule for calibrating our tools. The tool guru repeatedly told us to dump our high dollar dials and clickers and get the really old skool scale and pointer style. "They are nearly foolproof and survive the deliberate over torqueing, and the 15 foot drop test that Pan Am gives your tool kits." I have one but it only goes up to 100 ft lb. That's good for everything I do except my pickup lug nuts that require 130. I have a Harbor Frt special for that. I don't know how accurate it is but set at 130 it's definitely over 100.

I am in the same boat as you. Annual Cal per FAA. I have never not had one of mine Snap-on and Crapsman not pass Cal.[/quote] I have a TQFR100a that was sent back because it would not pass. I bought it used in the mid-nineties and used it bunches. [/quote] There is always that one in a million lemon in anything.
