torque wrench calibration
Tried to do a search on the above but didnt find anything.
I have a fairly decent looking torque wrench that i have aquired from a family freind but given that i have no idea of its heritage i would like to
get it calibrated before i use it.
- On the assumtion that wrong information is worse than no information.
Does anyone have and suggestions of where i can send it, locally or otherwise (loughborugh).
I dont need any formal calibration certs or anything clearly, although i would be nice to know its been tested correctly.
How much is it likly to cost?

Locost method?
Hold the square drive in a vice with the wrench horizontal. Hang a known weight off the end + calculate the torque. Weight/distance. Job done £0

I did consider that.
- You could even do a number of weights to check the accuracy accross the range.
- Presumably people do do this? How easy is it to then adjust it to correct?
What sort of acuracy would you expect from a mid spec torque wrench?

Search the UKAS website for calibration houses in your area.
TORQUE in the first box with your postcode then check the "Hand torque (tools)" radio box. That will give you your local cal house.
I pay around £20 for a UKAS certificate but if you tell them just for home use, no UKAS required it should be about half that.
Or, if you can bring it up here I can check it on our inhouse test machine.

Its a little bit close to that isnt it.
- For a decent the going rate seams to be around £50.
- But your not wrong, there are quite a few avilable for £15 odd.

How about getting a shear bolt similar to the ones mini's use to hold their steering columns on with - do they shear at a given torque (give or
take a little) ??
if they do, jobs a goodun and for the price of a bolt
