NutSerts What the deal?

[LibertyTC]

What is the deal with these nut serts?
Kj came with all the factory skids and am going to need to do the front diff & transfer case oil.
The skids have to get removed for this job, so are these Nut Serts re-usable?
Do I need the Nut Herts tools and rivet inserts, or can I simply remove and replace skids without any pain or discomfort....

You can re-use them. Do not go crazy tightening them back up.

Ok Thanks!
This is about to get interesting. Since the welding of the 1" steel down post got welded to the skid plate for the push Bar, hopefully my 2 bolt removable design works.
Due to the fact the the angle iron is blocked in at the bottom, as long as the skid plate can slide backwards a bit it should work. However, if the skid plate has to be dropped directly downwards, the bottom of angle iron may have to get cut, allowing the two bolt design to drop directly downwards..will see what happens. This one is going to get done on lift, no doubt.
