Rivet Nuts

[RoyKing]

Planning on using some stainless 3/8x16 rivet nuts to hang some skid plates under my Kubota M7060. From my research the two handle pop rivet like guns, fail when using the larger sizes, mandrels break and rivets get crushed unevenly. I found some simple wrench driven setter that looks like it will keep the rivet square.
Anybody experienced with them in the larger size

Those actually work pretty good as they force the pull to be perpendicular to the surface. The large pop rivet type guns sometimes are out of position because they are big and the person doesn't hold them square.

Hey, U can simply use an appropriate bolt/nut combination and while holding the nut pull up the insert with a proper wrench.

How big are you planning on doing? I do 1/4-20 rivnuts all the time with my smaller gun. The problem is people who have no clue who think they must squeeze like a gorilla and put too much stress and while doing that fail to keep the gun at the correct angle. Tht tool you've pictured will work but it's quite a bit slower. If you're only doing a half dozen or so then no big deal. So IMO it's not the tool but the operators who fail and then blame the tool that's the problem.

Want a little speed but not to over stress things.... Use you 1/4 (hex) impact driver with appropriate adapter and socket..... Just go lightly...

After noticing on a lot of car/custom tv shows guy using 1/4 inch impact screw drivers I dug mine out and got a set of Harbor Freight socket adapter and life has been good for "light" work...

I plan on using my impact driver with deep wall socket that way I can push downward while the setters nut moves up into the socket and box wrench on the lower section.

Does anybody have favorite brand of stainless rivnuts, and why

I'm not sure I would use stainless but that's just me.
McMaster Carr is my go to place, close enough that if I order Sunday evening I have it noon Tuesday.
I just make my own "tool" out of a nut and bolt and have never had an issue.

I tried setting some small 10-32 aluminum rivnuts by screwing down on them with a flat washer and it just spun.

My backhoe had some missing and it had hex shaped holes in the boom. I found the correct 8mm steel rivnuts with a hex base to hold it. Had no problem compressing those with a bolt and washer.

I’ve used a lot of the 8mm at work and never had a problem.

I've used Rivnuts often in aircraft.
Not familiar with current applications but can attest they work real good.
But I still have all my Rivnut tools!
LOL, but I have used all my 'nuts' so need to surf the 'net to get more.
Looking to the 'net to re supply!
