Torque Charts

These charts are meant to be used as guidelines for setting the torque on the NFA-Series electric screwdrivers. The
drivers have a torque scale on the torque adjustment nut showing reference numbers. These numbers determine the
approximate torque setting. Refer to the charts to determine the reference number setting for your torque requirement.

How to Read the Torque Charts

Torque ranges (lbf.in) approximate tightening torque, operated with no load at maximum speed. Verify torque setting
with a torque testing system.
