Well, I can tell you where that 2% "goes" When you twist the extension the energy is converted to heat. It warms up the extension slightly. One time is not noticeable, but do it one hundred times, and the extension will be noticeably warmer.

I will stipulate that there will be no practical difference in the torque applied to the bolt with an extension, as long as the parameters for correct wrench usage are followed.

While 2 percent is not a lot to be out, it is significant if you are torquing to above 80% tensile strength and if you consider that most torque wrenches read out up to 10% out when new (especially some of the cheap clickers). I guess thats why I like my beam style wrench, I had it calibrated when I bought it and found it out only 3 percent at 100 ft/pds. Since they don't wear and I have the indicator card from the testing/certification I trust only this wrench.

Manufacturers regularly compensate for socket extension torque loss by purchasing calibrated extensions (no wrenches to calibrate that way) but if you want to know exactly what your getting you need one of these babies.

Socket extension torque sensors

Oh yea...
