[RE-wrenches] Recommendation for torque tools

[william at millersolar.com]

Bill:

We use inexpensive, generic torque wrenches.  It is my impression that
accuracy in torque settings is not crucial.  We discovered that if we wrench
tighten and come back to verify with the torque tool, we have consistently
torqued at a somewhat but not significantly greater value than the tool
would have.  This tells me that hand tightening is not all that bad.

What is a bigger concern is missing critical bolts in the torqueing process.
We have developed some guidelines for this procedure:  We go back and
re-torque every bolt.  No talking or interruptions are allowed while doing
this.  Every crew member is assigned a specific colored felt pen and every
nut must be marked.

William

Wrenches,

Do you have a favorite brand/model of torque wrenches when assembling mounts
to manufacturer's specs? How do you handle calibration?

TIA,
