I lost the original thread from last year <?> ..
but regardless and irregardless ..
I bought a new torque wrench today - after returning my second
Princess Auto $ 50. unit - both fell apart in my hands -
just doing snow tires in the driveway 2 times per year.
The new $ 120. DeWalt is almost a foot longer ooh ;
has a very fancy plastic case ; Whoo-ooh !
But one point that was made in the original thread -
using it to loosen the lug nuts - the DeWalt has
several warnings to NOT use it to loosen !
The packaging says " limited 1 year warranty "
the web site says " lifetime replacement warranty"
Canadian Tire and Home Depot.
They are just today offering it in a combo
with a breaker bar ... $ 150.
.. the jury is out .. I won't hold my breath ...

I Knowing what their purpose is and what they are used for, I hope you didn
't need that warning. About the only time I could see using one to loosen a
bolt would be if you wanted to see if it was excessively torqued. Even the
n, not sure if you torqued it to 30 that means it will unscrew at 30, might
take more, but there should be a correlation.
A friend of mine was complaining that a tire shop had way over torqued his
lugs. He went back and the manager took a torque wrench, put it on a lug, s
howed him that it clicked at the correct value and said that proved they to
rqued it correctly......

I used my cheapo to loosen the wheel nuts - but I'm pretty sure
that was not the failure cause - they both had screws loosen off -
in different spots . I suspect that homeowner torque wrenches
do not measure the loosening torque . .
< professional tools - perhaps ? >
Re-torquing click does not prove that it wasn't
originally over-torqued ... duh.

Torque wrench reads both directions - has to, otherwize you could
not torque left hand nuts. The "prohibition" against using it for
loosening is the fact that the force released when a bolt snaps loose
is extreme and WILL throw the calibration off in time. If the bolt/nut
is not semi-seized, and comes off easily with no "snap" it will NOT
hurt the wrench - but you don't know how it will come off untill you
try it. That's why the "kits" come with a "breaker bar" - break the
nuts loose with the breaker bar, then run them off with the torque
wrench with the ratchet set to the "off" position. Why else would
they but a reversible ratchet head on a torque wrench????
I'm not arguing with Clare or DeWalt ... except -
.. why do they put a reverse option ?
on the cheap homeowner torque wrench that
is not meant for that task ?
.. and then print strict warnings to never use it
to loosen a lug nut ...

Two reasons. It is cheap to do. You may also want to measure torque on
lef hand thread.
I don't us chisels as screwdrivers even if they fit the slots or gefty
wrenches as hammers. But, this is America, you can if you want to.

The clutch basket nut on my (RIP Bag Lady) now deceased 1976
Shovelhead Harley was a left hand thread that required a 45-55 LB/ft

overtorque , it would crack the clutch hub - taper fit with a key to

I don't understand what that means. There is no need to use any torque wre
nch to loosen bolts, no skilled mechanic would do that. And if you use a to
rque wrench correctly, it will last a long time, especially for occasional
use. I would not buy even a cheap torque wrench and misuse it. Abusing it,
it will likely be way out of calibration long before it falls apart.
I meant for left hand thread *tightening*. When I was an apprentice, I
used to get to do a lot of wheel changing. We had quite a few customers
with LH threads on the LH side of their vehicle's wheels.
I had a cheapie version of this;
that I used on those wheels to get a reasonably consistent torque on all
wheel nuts - in either direction. It was consistency of torque that was
For engine work and any other place where precision was required, the
workshop W&B torque wrenches were used. We had a small one in inch lbs
for auto trans adjustments, a 1/2" drive unit for general work and a
3/4" drive unit for use on trucks and machinery.
Didn't use torque wrenches for loosening bolts - ever.
Nothing astonishes Noddy so much as common sense and plain dealing.

because, like I said, you sometimes need to torque a LEFT HAND
My 1/2 inch drive Snap-On micro-adjusting click torque wrench is now
ell over 40 years old - they don't have the jigs for recalibrating it
any more - and it has been used "in reverse" fairly often - but NOT as
a "breaker bar"
I remember the blurb from a Sturtevant that as long as the needle
pointed at zero it was accurate until the beam broke. I don't think I
have to worry about that in this lifetime. For most things I depend on
my calibrated fingers.
