FYI ...you can install those using the appropriate threaded bolt, I use a cap screw, put a nut and washer on the bolt, thread it into the nut sert with the washer against the exposed face , insert in the panel, then tighten the nut similiar as to how you would a puller, the nut sert will collapse on the panel back and once tight you loosen the nut, remove the bolt. Do a trial part on a piece of sheet stock , you'll see how the nut collapses on the back.....dk
