With the Rivet Nut Tool under 'Product Function' there are three options.
. Pull-out rivet
. Semi-Automatic Rivet
. Normal
What is the difference between the Three
The pull-out type is to pull out the nut, and the semi-automatic type is to retract the force arm to retract the nut. For the normal, the nut is retracted by rotating the knob at the bottom in the middle counterclockwise.
