I,

 

Ive got a Halfords torque wrench that ive had for a good few many years now and theres ben a few occasions where I suspect its not clicked when it should have done. Has anyone here had their wrenches recalibrated and if so where and at what cost?

 

Im wondering whether it may be cheaper to just replace it for peace of mind?

when mine was new , I put a bolt in me bench , then tighten it to a torque setting . and I go back and check its the same when I doubt it's working . top tip allways slacken it of when ya finished .

yer you can get em celebrated no idea where tho..

Some auto factors take in bulk torque wrenches and send them off for calibration, not sure on the cost as I just bought new ones as there was a waiting list as they hadn’t quite made the minimum required to send off. I need some ASAP so wasn’t an option to wait.

If itsithe small 3/8 drive one it's cheaper to buy new than calibrate that much I remember.

Assuming you purchase with the trade card.

Might be worth finding a local engineering company to see if the have a Acro torque or similar. You can then check your desired torque setting against the machine.

 

Even if you have the torque wrench calibrated you should still use an Acro torque to see if your selected torque setting is correct.

 

I'm lucky we have a digital Acro Torque which we must use every time we book a torque wrench out. (Aircraft Engineer)

I recalibrated mine with the aid of a youtube video.

Very easy to check accuracy at home. Wrench in vice horizontally. Move a known force further and further away from the pivot until it just 'clicks', that gives the torque exerted which you can compare to the setting on the wrench itself. Just do this at various torque settings as accuracy at one end of the scale does not confirm accuracy at the other.

If you dont mind sending to Norway, i can calibrate it for you.  As long as yours is in the range of 7 - 200 NM.  However, with postage costs from Norway to the UK, you will be nearing the cost of the ebay link above.

I have mine routinely 'calibrated' every year, though, there's never any adjustment done to them, it's merely a check to see it's working within it's scaled range. I have them checked at 20%, 30%, 50%, 70% and 80% of their ranges. I have found with some wrenches, doing a single check isn't enough.

 

Cost in these parts of the world are $60 + GST per wrench and that's to a traceable NATA Standard.

 

Many Calibration Shops who do Electrical Instruments and Industrial Instruments can do them I've found.

Try Norwich Instrument Services.

I used to calibrate the units torque wrenchs doing this same method. We had female 3/8 drive attatced to the wall with a wire that connected to a box. You'd set up the torque you wanted and a +/- tolerance
