Gentlemen,
 
Just a brief clarification about the warning not to use torque driver as a general purpose T-handle:
 
Vast majority of the customers, including you, would not be likely trying to unscrew some much larger fasteners, originally installed with lots of torque.  However there is always a possibility that some of the customers may attempt to do it. 1/4" hex drive has its limitations, typically, it works real well up to 200 inch-lbs. Larger torque may cause damage to this relatively small size drive. On the tightening side, driver does not let the user to exceed 72 inch-lbs., and fully protects 1/4" hex drive from any serious damage. However, if somebody, who is really strong and determined, grabs the driver by the metal arm and attempts to remove some "frozen" fastener, say, larger that 1/4"-20, the value of the torque required to accomplish this task may easily exceed 200 inch-lbs.
 
Also, fasteners, even small size ones,  installed with thread lockers (Loctite and other brands) may be much harder to remove in principle. If you happen to run into the need to remove such fasteners, please use either L-shaped allen hex key, Mountz mini ratchet or other similar tool.
 
People with understanding, like youself, can certainly use the torque driver to remove fasteners installed with use of the same (or similar) torque driver (wrench), by holding it by the metal arm itself, without any issues. I do include Mountz mini ratchet wrench in MG3-SRA to speed up the process in general and to "protect" 1/4" hex holes of the torque driver from excessive stress if somebody decides to remove fasteners installed with much higher torque  than my driver is designed for.  So, this warning is included, let's say, just in case...
 
Boris

The wheeler did and does work, but mine is off on it's calibration.  This is one of those times where you do get what you pay for.
 
You can use the Borka kit for loosening - I use the mini ratchet that came with the kit all the time, and have used the torque bar for loosening as well.  I believe that the printed warning refers to the fact that it will only be accurate to the stated value when turning in a tightening motion.  Boris will have to verify.
 
This is a great piece of kit.  Well thought out, simple, durable, and packable.   The TAB Gear roll up pouch is great also.  I have the SRA Kit, plus a few more bits that I added and it all fits nicely.
 
This is a fine example of you can pay more, but you can't buy better.  When you consider all the torque values you cover with this kit, compared to the individual seekonk wrenches the Borka's value becomes readily apparent.
 
After using my Borka SRA for several months now, I'd buy another without a second thought.

I have a Wheeler and have used it for years quite successfully.  I have checked calibration regularly and it has always been within spec, actually, until recently, better than spec.  It has degraded to +/- 1inlb in the last year.  Still spec... nothing wrong with Wheeler.  I do like the Borka as a "bag unit" better, though.  It is more useful as a field tool.  
Opinion,untempered by fact,is ignorance.

That was in the purpose of the design - to make a "bag unit", field tool... No more, no less.
Thank you for clearly expressing the rational behind Borka products.

What a great tool. I got to use mine today mounting base, rings and scope to rifle.It worked like a charm.... I really like the idea that bits are held in place while using and all parts in the MG5 kit look to be quality stuffThunbs Up

Help me out here....Bucky

There's 2 sides to the bar. One side has a torque value of 36 in pound, the opposite "hole" on the other side is 15 in pounds, I think. 
How does the tool "know" which torque value it's using??

I know this is an old post, but I have checked my Fatwrench often, and recently, and it is dead nuts on its torque settings.  I know that several Fatwrenches have often gone out of spec because they were stored with a load on the spring.  They need to to be stored without a load.

There are probably tens, if not hundreds of millions of pre-set torque drivers, all of which have spring compressed to a certain value (pre-loaded), and they work just fine for many years. Valve springs in car engines are heavily compressed, stay like this for decades and in addition, work for hundreds of millionds of cycles. What I'm saying is that leaving spring compressed can not do any harm unless spring is compresssed to nearly solid height for several years, in which case, there may be indeed something happening which spring engineers call "spring relaxion" - spring looses some portion of intital spring rate, typpically between 5 to 10% in several years. Of course, FAT wrench, being made in China, probably has an extremely high quality spring inside Eek, which needs to be treated in some special ways to work right. Springs made in some less sophisticated, then China, countries, can be left compressed with no loss of accuracy.  Also, I'm exicted to hear that China FAT wrench is accurate within +/-1 inch-lbs. for all torque settings from 10 to 65 inch-lbs.  I'll gladly pay $5,000 to anybody who can submit at least 2 independent third party reports confirming that, because  I can then sell these reports to Chinese maker of FAT wrench for $50,000. They'll pay any kind of money to hear they make the most accurate torque tool in the world...

To the owners of FAT wrench, who claim their wrench to be within +/- 1 inch lbs. for any settings from 10 to 65 inch-lbs. -
 
I was unlucky not to be able to come across anything like that. As an engineer who does torque tools for living, I think it is not feasible. But, I may be wrong, so 
 
here is my bet:
 
Send me your FAT torque wrench, I will then send it to Mountz, Inc in CA, the leader in industrial torque tools, to use their very sophisticated lab, compliant with all world standards, to check for deviation of torque output between 10 and 65 inch-lbs. If you happen to have a FAT torque wrench with just +/- 1 inch-pound deviation for any torque setting from 10 to 65 inch-lbs., I'll buy your torque wrench for $1000. If your torque wrench is not that accurate, and deviation for any setting between 10 and 65 inch-lbs, is more than +/- 1 inch-lbs., you will get your wrench back, but only if you pay $125 cost for the lab check, which would be my cost of doing this procedure at Mountz. 
 
Results of this lab check will be published in public, with reference to the actual owner of the wrench and with full disclosure of all technical details.
 
Anybody wants to take this bet?

My post was not meant to put down the Borka tools.  I had, in fact, planned on purchasing some myself.  My post was to confirm, that in my experience, with my fatwrench, I have had very good luck.  My gun-nut buddy has a Snap On QD150, which is supposed to be pretty accurate, and is in line with my fatwrench.  I have had it for four years.  It has been a good product for me, regardless of where it was made.  Is it as good as the Snap On or Borka, probably not.
 
You forgot to mention magazine springs.  They can stay compressed for decades without ill effects.
 
 
EDIT:
 
I had this reply window open while you posted your other "bet" post.  I like that post a lot.  That is putting your money (and products) where your mouth is.  I can't take your bet, as I don't know if mine is that accurate or not (we compare in 5 in. pound increments against the Snap On -  maybe that is too course, but it is good enough to me), but I will send you my fatwrench if you want to have it tested for your own promotional material, at your expense, and you could let everybody know how it turned out.  It seems like mine is a pretty good one.

Matt,
 
I mean no offense, of course.... Just was having a little fun, but on a serious note, and after spending some time researching torqgue tools, some things become pretty evident. You're right of course, about mag. springs.
 
I do not need to take down FAT to promote my tools. It's just this itch of the enginner, you know. We're like pigs, like to roll in a mud sometimes...
 
In my observations, it's practically impossible to have spring based adjustable torque driver with +/1 inch-lbs. or less deviation for the whole range from 10 to 65 inch-lbs., made in China, Germany or anywhere else... The reason that it is imposiible is simple - linearity of the compression spring, which is limited, say, to decent one only between 25% and 75 % of the load. Which is 1:3 ratio for a decent linearity relative to the load. 10 to 65 is 1:6.5 ratio. Not going to be linear, deviation will vary considerably between low, middle and high settings.
 
But if somebody does have one THAT accurate FAT wrench, I would like to have this "abnormality" as a collectors item. But I do not believe my 1000 bucks is in danger...
 
I'll check with Mountz, if they agree to check out your torque wrench for free, I'll take your offer.

Excellent.

PM me if you want to set it up. I would be very curious about the results. Do you have results on the accuracy of the Borka already? If not, a head-to-head comparison would be great, as the FATwrench is a commonly purchased tool.

Whichever number is facing toward whatever it is your tightening is the number that the tool is using. 
It is in the instructions.

Right, I get that, but wouldn't it be the same torque value?? (I know it's not.)

It's a great piece of kit! I mounted a scope, and checked the action screws on my Remington.

Keep in mind that when you are tightening something, you are applying clockwise tangential pressure onto the groove on the torque wrench handle.  If you flip the torque wrench so that the other set of numbers is facing toward the fastener, you the same clockwise pressure is now trying to bend the torque wrench in a different direction (since you just flipped it), right?
