Hi, what torque wrench/screwdrivers do you folks use?? What do you think about the Klein 25pc set. Its a bit pricey.
That’s pretty cooloccasionally use a torque tool on head bolts and always on anything on aircraft (since there is an inspector standing there watching) .
residential electric, have never used a torque tool, rely on muscle memory or with copper or aluminum go by first feel of yield. Even doing hvac flare have never had a leak going by first feel of yield. Last time using torque tool on non-aircraft electrical was over 30 years ago inside Minuteman missile silo.
caveat - after 70+ years of using fasteners (since before 10 YO) until about age 70 was within 5% when anyone checked. Have found that I need to 'recalibrate' every year as strength decrease is now noticeable.
And stuff I had put in the car trunk has somehow gained weight when I went to remove it.Have found that I need to 'recalibrate' every year as strength decrease is now noticeable.
Oh no!Anyone on 2017 code and newer and not using a torque tool is violating the code
2023 NEC 110.14(D) Terminal Connection Torque.
Tightening torque values for terminal connections shall be as indicated on equipment or in installation instructions provided by the manufacturer. An approved means shall be used to achieve the indicated torque value.
2020 NEC 110.14(D) Terminal Connection Torque.
Tightening torque values for terminal connections shall be as indicated on equipment or in installation instructions provided by the manufacturer. An approved means shall be used to achieve the indicated torque value.
2017 NEC 110.14(D) Installation.
Where a tightening torque is indicated as a numeric value on equipment or in installation instructions provided by the manufacturer, a calibrated torque tool shall be used to achieve the indicated torque value, unless the equipment manufacturer has provided installation instructions for an alternative method of achieving the required torque.

Side note: At an IAEI class they asked how many of the over 100 attendees owned a torque driver ( less then a third ) and how many send it out for yearly calibration ( what's that ! ) That was a few years before pandamic so hopefully more electricians now own at least one torque driver.Hi, what torque wrench/screwdrivers do you folks use??

Thankfully they took out the calibration requirement in the 2020 NEC.Side note: At an IAEI class they asked how many of the over 100 attendees owned a torque driver ( less then a third ) and how many send it out for yearly calibration ( what's that ! ) That was a few years before pandamic so hopefully more electricians now own at least one torque driver.
But, the way I read it, the AHJ can still require it to be calibrated because they have to approve it.Thankfully they took out the calibration requirement in the 2020 NEC.
