you dont need the tool to install the inserts
Just put the insert in the hole and place a piece of steel plate or flat bar with the corosponding sized hole in it over the nutsert , then put a bolt through the hole and start screwing it into the nutsert, use the steel to press the nutsert into the hole as you do it, then as it tightens up the nutsert will set in place.
i know that desc is a little long winded , but if you do it, it will all make sense.

Have you tried this before?? I have and it only works occasionally. Or you get about half way through pulling the nutsert up and it starts to spin then you cant even undo it unless you can get behind it and hold it. But if you could get behind it you wouldnt need a Nutsert.

Whats the "correct" way to do it?

You use the proper tool, a couple available, for small ones it is like a pop rivet tool or a heavier duty one uses a ratchet to tighten it up and lock it in place.
I've used the bolt method and a really heavy washer on larger ones that are too big for my pop rivet type toolwith great success.

One of the guys at work bodgied up a pop-rivet tool to do M5 inserts. Worked reasonably well until the Production Manager coughed up for a genuine tool.

I had nutserts on my ARB winch bar for spot light mountings on my Rodeo. Crap method I reckon as they spun in their holes and the spotlights vibrated a lot. I ended up ripping them out and mounting the lights straight to the bar.

I have one you can borrow if you wish, I am in Berwick.
Also I have found that elongating the hole slightly with a round file gives the nutsert a mecanical grip as well as the crush and stops it from spinning after a few years of abuse.

try using weld serts they are the same as nut serts but are a lot stronger as they need to be welded into place

Grave dig.
I needed one of these tools to install a "pet barrier" in the back of the P38, unbelievably I could not find any local supplier at a reasonable price.
In the end I bought this one from a UK ebay store. About $40 delivered.
http://cgi.ebay.com.au/ws/eBayISAPI.dll ... 0342890480
Works perfectly and now I suspect I'll be using 6mm nutserts for a lot of stuff
Just thought it might be useful info for someone.

I have used those and they struggle with the steel nutserts.
With the alloy ones it is even more important to ensure the tool is adjusted for material thickness as it is very easy to pull threds.
Also make sure where you place the nutsert is flat on both sides. I have been through about 3 or 4 6mm bits when the double skin behind was not flat and bends the arbour as you pull the nutsert off. They are about $5 ea so no big deal.

I'd expect the hand riveter style would still be hard work on the bigger nutserts, we got the lazy tong style one at work recently and as long as you can get into the space properly it works great. If you could get it for similar money to the one pictured I'd go that style. Also seen a small one that looks like a racheting tap handle but they can be a bit hard to use on bigger stuff also.
I tried the pull it in with a bolt trick on some stainless ones and failed every time. If you can get in behind to tack the nutsert I reckon you are better off tacking a nut in there instead if you are neat.

I use this method but modified a little.
I use several greased flat washers and a greased cap screw to pull the riv-nut up, I use a drilled out nut with a ring spanner to hold the riv-nut in place and a little turned up collar to keep it centred.
Works great, but yeah the real tool is easier if you can find them. I use stainless rivnuts on some things, you need a solid tool to put them in.

Mine looks like this

about 400mm long, pulls 10mm no worries. Was dear though, but will have it for life.

ive done about 6 with the bolt + steel trick, only had 1 that wasn't crimped enought and had to re-do.. probably not as easy to do with the proper tool but still possible.

another way i ve had success is using a nut from a dyna-bolt
it has a serrated back - hold the nut with a spanner & the serated back keeps the nutsert stationary, then use a high grade bolt to wind in/crush the nutsert.
