How to use a torque wrench

Today's bikes are tough, but they're held together by fasteners that mustn't be stressed. Many components come with recommended torque settings. Breach these settings and you may void your warranty.

It now makes sense to use torque wrenches. Torque is a measurement of torsion, a twisting force. A "torque wrench" has a spring-loaded indicator that gives a numerical readout of the amount of torque being applied through it.

To check the recommended torque settings for the components on your bike, visit http://www.weldtite.co.uk where there's a list of recommended settings.

you dont use a torque wrench to undo bolts

you use a breaker bar

[extremeXJ]

you should never use a torque wrench to loosen a bolt.

the counter-clockwise setting is for use with left hand threaded bolts/applications.

Horrible video. You hardly showed us how to calibrate the torque.

@colombiajunior no offence like but thats aload of bull do the heck use them to undo bolts in space and if you have a snap on torque wrench like me you dont wanna use it for that!

[colombiajunior]

@barnettboys13 you can for specific applications. for example when astronauts are in space they use torque wrenches to undo bolts. otherwise u risk breaking a bolt and not getting something out in space. but yea , in most situations ur not gonna worry about that.

As long as you don't exceed the wrench's maximum torque specification, it is not harmful to use it to loosen something (be careful though!). There are rare occasions when you might want to know the torque necessary to remove something as an indication for re-tightening.

You will throw off the calibration if you unscrew it to the point that the handle disengages. As far as I know it will not upset the calibration UNLESS the handle comes loose, but I could be wrong.

So this is a video on how to use a torque wrench? Gawd. If you don't know how to use a torque wrench... don't watch this video!

I thought you use a torch wrench to tighten.

A mechanic buddy of mine says that's the best way to store them because it doesn't keep stress on the spring inside there. I'm not really sure how to set the dial on my torque wrench though that's why I was watching this vid
