Why do you need one? There are few things (collapsible one-shot
collars is one) that require to be assembled to an accurate torque.
Mostly the function of a torque wrench is to assemble a number of
fasteners to a _consistent_ torque. Short-term repeatability matters,
but accuracy isn't really that big a deal for most tasks.


A lot of mechanics are very strong and a lot of the nuts and bolts -
especially when alloy cases came into common use - are easily broken or
stripped. Hence the other bike repairers friends, the helicoil and broken
stud extractor...

Well worth using a torque wrench so long as you make sure to set the gauge
properly, and, if in doubt, pull it with a spring balance just to make sure.

Mind you, some cylinder head bolts just feel silly tight when one tries to
get them to the figs you may find in a typically translated manual, so some
discretion and common sense may save you the odd embarrassing snap or strip.
