Thanks for sharing! We have purchased a possibly identical tool and some 10-32 inserts from Hanson rivet. Before we use it, I'd like to ask a few questions.

What sort of error? How can we eliminate or at least reduce this error?

Drill a close fit clearance hole for the size you are using in a piece of thicker steel. Put a bolt through the hole, screw the rivnut on the other side so it's tight. Place the rivnut in the mounting hole where you want it and use a powered drill to turn the bolt. Tightening the bolt will pull the rivnut bending portion tight to the mounting hole.
The tool we purchased pulls on the mandrel/bolt linearly, not through torque applied to the threads on the insert. Does pulling it this way result in a good set, or does the buckled part of the wall tend to twist under the torque?

We purchased steel inserts. Has anyone used the aluminum ones, and if so, what have you used them for, and how have they held up? Using a threaded aluminum fastener to secure a chassis or mount a manipulator sounds like a stretch.

Finally, the tool we have has several adjustments in order to fit the specific insert being used, particularly the mandrel extension distance. As we have only purchased a single size insert so far, this should not be an issue, but if you use multiple sizes, how successful have you been at getting students to do the adjustments whenever they change from one size to another?

Edit (addition):

We also use the hand tool. We keep all of our rivet nuts in a special box with the gun.
Are the c-channel and tube spacers part of the bumper? How about the corner brackets?

We will also have a box just for the riveter, inserts, and the less-common sized drill bits needed for these inserts.
