Riv nut installation tool

I have the nutsert tool that so resemble the rivet gun....however I personally think the other nutsert tool that is hand held and used a wrench and allen wrench does the better job of installing the tool due to what I think is the ability to apply a bit greater pressure very much like the home made unit above... I just set aside in a baggy the amount of nutserts to install the roof rack on my 51 Plymouth 2 door wagon..these pups give you the ability to pull the fat out of the fire so to speak
