Agree best to have tool for stainless, actually ordered a tool today for just that (3-12mm range of Nutserts). All set up ready to go but have to wait until Friday for tool.
Need to do 6mm SS now, will give the nut and bolt method a go in a piece of scrap plate to see as the wait will get the better of me...
I bought a whole kit a while ago, with tool and nutserts. Have only used it a couple of time and found when pulling up the nutsert using the tool I have stripped the thread inside the nutsert. I think I haven't had the tool set right for the thickness of the paneling, but the kit came with instructions that are pretty much useless. So as of late I have just done it by feel with success.
Very handy item to have though.
Yeah, the tools have quite a bit of leverage... on smaller sizes up to about say M6 its easy to pull the mandrel thru the Nutsert if you don't set the tool correctly or lapse into Schwarznegger Mode... goes off with a bit of a bang when it does too, eh :-)Quote:

Did a successful trial set with 6mm SS Nutsert using the bolt / nut and washers method in a piece of discarded body panel (had sharp edges). Solid work to set it though-significant torque was req"d.Quote:

Was able to get my trim tool under the Nutsert flange and lock it from turning and unscrewed/removed the remaining threaded bolt shank. Nutsert remains 80% set in pillar and will finish off when tool arrives. Just have to wait for the tool. Plenty to do.
Commercially these days in our little game we’re on pneumatic (exy priced) nut/riv guns but the old days found any and all methods really appreciated 2 x washers with grease in between prior to readying the serts for squishing [emoji106][emoji106]
EDIT: Preferably shiny SS slippery washers!

Grease is what I recon could have improved outcome. Used small new SS washers.Quote:

If I recall correctly back then John mate, including all above good blokes tips and tricks like ours on the fly. Pretty sure we were happy using mild steel bolts and butchering their bolt threads each second tough sert. Probably a bad plan mate although piffing out MS bolts back then seemed to get the job done easy greasy and home [emoji106][emoji106]

I've had an air hydraulic nutsert/rivnut tool like this https://www.ebay.com.au/itm/Nutsert-...mJZE:rk:1:pf:0
for years now. Less than half the price now to what I paid & IMHO worth every cent if you have more than one or two nutserts/rivnuts to put in ...... & if you have one of these you will tend to find more uses for rivnuts/nutserts in your life.... I guarantee it! If you have a compressor you need one of these.
Picked up a hand operated rotary nut loading structure with 8" handles (M3-M6), compact size but was handwork to set 6mm zinc plate low carbon steel nutserts.

Had success but think air/hydraulic would be a big improvement. Thanks Cuppa
