- Someone reminded me of a good way to keep your torque
wrench in calibration for a long time. I'm sure we all
use the clicker style torque wrenches these days - though
I do have a beam type wrench kicking around somewhere.
The trick to keeping a clicker wrench calibrated is to
always reset it to "0" after every time you use it.
-
- To torque a bolt to 30 lb-ft, I'd set it to 15, click
it, then set it to 30, click it, click it 3 more times -
then set the wrench back to "0". Always put it away in a
case set to zero. The idea is to keep the internal spring
from being loaded more than it has to be. If it
stretches, there goes the calibration.
-
- Never use it to remove a bolt if possible. If you
have to use it for that, increase the value by several
points; if the bolt is torqued to 30 lb-ft, set the
wrench to 40 lb-ft (or more) and remove it, then set the
wrench back to zero.
-
- A torque wrench is a valuable tool and only as good
as the guy using it and the way in which it's used.
Someone once said, if you have a $10 head buy a $10
helmet. I'd say if you have a $10 motor buy a $10 torque
wrench.
