Any recommendations on a riv nut tool?
4mm-8mm THREADED RIVNUT RIVET NUT INSERT SETTING TOOL on eBay (end time 12-Dec-10 10:44:20 GMT)
Or pay the extra for something like this.

And another option.

I managed to break 2 of the first type it was okay for the smaller rivnuts but when used for the larger ones they sprained. May have been too much pressure or nut up to the job not sure.
I have one similar to the cheap one.. it's great for using smaller sizes and ali inserts but is a real struggle with M8 stainless ones
If I was starting a new build I would go for the second one.
If I only had half a dozen or less to do I would get the cheap one
We had a demo of the second one at Newark earlier this year.
It was so unbelievably effortless, even with stainless rivnuts, that we suspected he was using extra thin rivnuts.
So we took some of our own stainless 8mm items along the day after only to find that it coped just as easily!
So we bought one.
Recommended.

I bought the first one and broke it, should've got the second one.
I repaired my el cheapo by replacing the center pivot with the circlipses on by a bolt.
What happens with the cheap ones is that when you put pressure on that the sides open up and the circlipses bend, a bolt with large thick washers
won't budge and keeps the tool in 1 piece, so might do that before breaking it 
I used the bolt + steel plate + g-clamp method.
have not had the need to buy a tool (or replace the one that broke on the second nut)
(FYI if you are not familiar with the method, drill a hole in the steel plate, insert bolt and screw rivnut onto the other side. Then insert the
rivnut where you want it to go and use the g-clamp to hold it down, then just tighten the bolt and the rivnut is installed.
I used this only with ali rivnuts not sure how steel one will cope)

That sounds interesting but I'm not quite seeing in my head, and chance of a sketch?
I've got the 3rd type. Very robust & easy to use. Looks like it's a bit more compact that the 2nd type also.
I have a large, one like # 1, but the # 3 gets very handy expecially when working on the driveshaft tunnel. I had to destroy the 31 type one when after incerting the rivnut there wasn't enough room to remove it.
I bought one of these...

cost me £55 from a show but never regretted the expense.. a superb tool and excellent for setting tougher rivets as well...
only drawback is it is a bit large so you cant always get into those small places...
I have one of RIVNUT/NUTSERT SETTING TOOL SILVERLINE M4, M5, M6 & M8 on eBay (end time 26-Oct-10 18:55:56 BST) for about
12 months, pulls 8mm steel rivnuts easily,and has had plenty of use
I did something similar when I had a small number of M8 steel rivnuts to set (didn't warrant buying a tool as there were so few to do).
I would recommend a good smear of grease on the bolt, and a few greasy washers under the nut, to help things along. Don't expect the bolt to
last too long either, as it takes a fair bit of force.
