I've got a teng tool torque wrench which needs re-calibrating. 

 

I used it to its max on the front hub nuts off my car and ever since its been wildly inaccurate - It snapped a wheel stud when I tried to torque the wheel nuts. 

 

I'd rather get it re-calibrated than replace it - Although i'm not massively impressed with it since it shouldn't be damaged since I used it within its rated limits. 

 

Either way, the teng tools website is really hopeless, can't find anything on there. I've tried contacting them but got no response. 

 

I contacted a UK teng tools dealer, he quoted me £60 for re-calibrate it. But the torque wrench was only £65! So may aswell buy another at that price. 

 

Anybody got any other places I could try? 

 

Especially if its somewhere close to Manchester, as I could drop it in rather than post it

Places that sell garage equipment ramps and the like, Tecalemet used to do ours and as a job lot worked out at about £30 but its all about cost and if your wrench can be put back in calibration without replacement of parts. Pop in your local ATS and ask who in your area calibrates their torque wrenches to keep their ISO certification

Do it yourself... plenty of videos on YouTube showing you how.
E.g.

  That will only show you if it's accurate or not, it won't allow you to recalibrate it to the dial.  You would have to test it every time you set it to a new figure, which would be a pain.  Getting it re-done is the best option.

Yes it can be a lengthy process but it does work.
However, if the OP's wrench is so I accurate it's shearing wheel studs then odds are it's knackered

My experience of teng torquewrenches (and indeed their ratchets) is that neither are very good,

If it's a micrometer style torque wrench, remember to turn it back to its lowest setting between uses. And if stored for a period of time, you need to click it a few times at 3/4, 1/2, and 1/4 of max value. And make sure you're storing it where it isn't getting banged around in the toolbox.

I think you're supposed to loosen off the barrel too if you're not using it.

 

Norbar have done mine before and they also offer the service for 3rd party equipment- Not cheapy cheap though....

I do always store it unwound and its sits on a shelf. As for storing it for a period of time, I might only use it twice a year - So does it sitting for 6 months do it any damage? 

 

I'll get in touch with some places and see what prices I get. 

 

If its really inaccurate like it is at the moment could it just be knackered? If it needs parts replacing, then recalibrating then I think it'd be cheaper to just replace it. 

 

I may even just buy one of the £20 clarke ones from Machine Mart. It did me fine before for ball joints and suspension parts - I only replaced it with the teng one when I built my engine...
