accidentally wound torque wrench down past 0 whoops.

[mikojh]

Did this and the wrench went slack tightened it back up to zero could feel the tension gripping at 0 so hopefully its not screwed (I did this about 4 times thinking hmmm this is odd lmao). Would this knock it out of calibration? Phoned draper they couldn't answer. Is it worth getting a replacement?

I would send it to Draper UK or try these people

If you depend on accurate settings then it is a good idea to have items like torque wrenches calibrated regularly.I have four of them and get them done every six months or so.

This is brand new and has already been calibrated. I'm just wondering whether my carelessness and winding it down past 0 would actually knock the calibration.

[Fizzer Thou]

Torque wrenches should always be stored with the preload turned right down.My 1/2" and 3/8" drive wrenches are turned back so that there is little or no tension while waiting for the next time they will be used.It does not put them out of calibration.

I always turn mine back as far as they go so there is no tension.

So its safe enough to take it just past 0 so there is zero tension and can store it like that? Past zero is becomes slack and when going back to zero the tension comes back thought i may have messed the calibration up by taking it past zero buts its quite safe and good practice to do this anyway?

Check it against another torque wrench. If they both click at the same time when set to the same torque setting it's a pretty safe bet that they are both reading correct.

Im quite often dont bother winding mine back, but its old and probably due for replacement. Im guessing its not even within 20%.

Am I correct thinking a weakened spring will always indicate more than force applied = under torqued bolts?

The manual of my torque wrench definitely told me to store it on a low setting but higher than 0 as well. It also said to wind it up and down a few times before use as well (if it hasn't been used in a while), so I always do this.

I read on bcf recently that people don't use torque wrenches now as they can't be bothered.



If there is no Zero mark then do not wind it past the lowest number.
That instruction is possibly to prevent unwinding the center tensioning bolt off the core of the universe. Which maintains our planet's orbital equilibrium.

You know wot you've just gone and done now don't you..

So past zero is fine i.e. no tension g2g then? Don't know why draper have to give conflicting instructions. I've never owned one before hence the probably seen as daft questions.

[mikojh]

Someone from draper has just called me and basically said it should be stored at 10 which is something to do with the spring setting if left at 0. he also said winding it down past that could knock the calibration out and offered me to send mine in to be swapped. Not sure whether to get a replacement now or not as it been set on 0 for the last 24 hours. Their even changing the sticker on the ratchet lol.

First off mate, there is no such thing as a daft question , and secondly - it's up to you if you want to get the replacement - probably wouldn't hurt if they're offering you a new one , but I personally take manufacturers instructions with a pinch of salt - they can be an anal bunch at times!! - I've always wound the spring tension off completely when not in use and never had any problems at all, the only thing I would say is before you use it just wind it up and down a couple of times first then set your desired torque and that should make sure the spring is properly seated.
