I get the torque wrench out occasionally to check, especially if
using some new hardware with different specs. However on a daily
basis, I generally do it by feel. I have come across an amazing
number of over and under torqued connections over the years, though,
so it really is an issue for all of us to watch out for. Even
though I'm not toting a torque wrench up on the roof, I still hand
tighten the final half turn on all connections, to make sure they
are right. I don't run a big crew anymore, but I could see the
advantage in having pre-programmed settings for the new people.<br>

strategy is to have several spares in a multi-bay charger,
and change out when the battery reads 50% (2 bars).
Subjective, I know, but we are talking in-lbs when
tightening rack hardware, not ft-lbs. Anyway, I’ll report
back to the list once I get my programmable M18’s and try it
out.<o:p></o:p></span></p>

I’m curious, how many of us actually use a torque wrench on
the job with any regularity, be it rack or electrical
connections? I have never seen an everyday electrician use
one, even on serious industrial work in a tightly controlled
jobsite. Every lug, connector, fastener has a recommended
torque. I think we all have seen the damage heat causes as
the result of a loose connection.<o:p></o:p></span></p>

noticeably with discharge, and also with higher amp hour
packs. My drill screams with a 5 AH pack! I agree its less
of a drop with discharge than with lead acid or NiiCad, but
its still enough to make torque settings inaccurate.<br>

I understand it, there are 4 buttons on the drill, each
can be programmed to one of 10 torque levels through the
app. And yes the torque levels are 1 – 10, not torque
values. For example, tighten an L-foot to a scrap piece of
rail at each torque increment, measuring after with a
torque wrench, til you have the values of each increment.
Then program the drill buttons to your most often spec’ed
torques, and you’re done. Just press one of the four
buttons on the drill to get the required torque. The
values are set in the drill even with battery removed.</span><o:p></o:p></p>

<p class="MsoNormal">I thought the idea of being to preset
torque RPM settings from the app was good, my reasoning
being have one impact set (by the boss, behind password)
for installing racking lags, another set more delicately
for mounting equipment, etc, but watched one of their
videos and the torque is not calibrated to in-lbs, it's
like a range of 1-4, and the app lets you do a 2-1/2 for
example. The actual torque is up to you to figure
out.....so you still need calibrated hand torque wrenches.<o:p></o:p></p>
