Re: {Chrysler 300} torque wrench



quick comment , i broke a critical bolt once with clicker because I read vernier scale wrong , setting it  . very easy to misread a vernier scale in the moment , or off one whole turn . I hate them . Make a mistake, may cost you an engine block  . 
You hear the click but you don’t really know if that is accurate on a given day. Or how close you are to it clicking as you approach it .   Maybe good in a  factory.  
If beam / pointer is on zero it has to be very near correct , bending of steel is totally repeatable . And you can tell / get a feel as it approaches the desired setting , especially if doing in 3 steps. Reset the clicker 3 times? 
Feel matters a lot as you approach full torque if something not right?   
Last , process of torquing bolts itself will have errors way more than 2-3 % , tapped thread variations , lube , bolt hardness , rolled or cut threads , washers, bolt finish or plating  etc . Why for really precision setting like race rod bolts  they measure stretch .
To each his own . 
Craftsman tools to me every bit as good as snap on , and Kobalt seems ok especially for the $, but it gets down to “like buying bmw for the  kidney grill and free monogrammed driving gloves .”  
And all that is  ok if it makes you happy !

As someone  that has calibrated a lot of torque wrenches, stick with what you have and have them checked periodically.  

Ask 10 guys, and you'll get 10 answers and 9 of those answers will be BS. 

Three types of torque wrenches for the average guy  in their garage.

Beam type. This is your old style torque wrench that has been around forever. Dependable and accurate. A little  hard to read and some parallax error can happen if you don't get your eyeball over the pointer. Generally approx 3% accuracy.

Clicker type. Everyone's favorite. Dial it up  and feel for the click. They are OK, but need to be checked and used periodically. ALWAYS crank it down to a lower setting to store. If you forget, go "exercise" the wrench by tightening some lug nuts or something like that and you'll probably be OK.  Accuracy is usually 4% CW and 6% CCW

Dial Type. These are the most expensive and most fragile of the bunch. Also the most accurate. They are basically a beam type wrench with a dial indicator that measures deflection (kinda over simplified) . They can be very easily overstressed and then they aren't  accurate at all. They really belong in the lab rather than the garage, but your Snap-On rep won't tell you that. Accuracy is 2% for the better ones, 3 % for the cheaper versions but some with are available with 1% accuracy. 

Treat the torque wrench for what it is... a precision tool. It's not a breaker bar. That seems to be the biggest abuse I see.  

The cheap (Harbor Fright) torque wrenches aren't bad. The Snap On reps go berserk when I say this, but I've found just as many bad Snap-On wrenches as I've found Craftsman and whatever brands. It really comes down to the guy with the $40 Harbor Freight wrench might keep it in the drawer with his mics, and the  guy with the Snap-On wrench might use it to break rusty bolts loose. Just take care of it. All the tools are crap now. 

I have the clicker and the beam type in my box. The SK beams are close to celebrating their 50 birthdays and the Utica clickers were some that I pieced together and repaired (and checked) .

I had a look at my old torque wrenches
and made me wonder what do
people like in modern torque wrenches these days.
