Just thought I would share my findings with others to make sure everyone else uses about the same running torque?
Please let me know if you are the same / significantly different!!
Setup was an AN3 or AN4 bolt held in a drill press vice which was clamped to the table so it couldn?t rotate. I then ran the nut onto the bolt so that about 1 thread was showing out the end (so full contact with but threads by the bolt). The scale was read while the nut was in motion, and the wrench was held at the end on the black knob.
Findings were (measured running torque):
AN3 / MS21042-3: 10 in/lbs

AN4 / MS21042-4: 24 in/lbs

As such on my click type torque wrench I would use as the wrench setting:
AN3: 38 in/lbs (28 + 10)
AN4: 109 in/lbs (85 + 24)
Look forward to some concurrence / discussion!
