Anyone know if these rivnut tools can use stainless rivnuts. Wasn't sure if the tool was strong enough for non aluminium nuts.

I’ve gone through three of those style tools in the past and they will do steel rivnuts but the threads on the mandrels tend to die.
If you e only got a few to fit they’re ok but it’s not a lifetime tool.


I have one of these now and the mandrels are a nicer design and have done more work than the three cheaper ones I had previously.

me got this one https://www.ebay.co....OL/372015414770

top tip don't tight the rivnut all the way up leave a mm gap between nut and gun otherwise they get stuck

i have one that does up to 6mm in steel. i got it as i had a lot to do, but you do not need to have one to fit them and for larger than 6mm i use a bolt some nuts and some washers.

I have this tool, but was contemplating using stainless nuts thinking the threads would be stronger

[nicklouse]

false thinking- stainless is generally weaker that mild steel. Stainless also corrodes mild steel that it is in contact with if damp. look up galvanic corrosion. we use stainless weld nuts and have steel bolts that are a service part so they dont fail.

just use steel ones. stainless is just a pain. did I mention galling?

It's a play on words. Galling means annoying. It was meant as a joke.

Ahhh I see, thought it was some strange meaning for screws or something

Actually galling is when a thread picks up typically Stainless steel and ruins the thread. It’s something we suffer a lot with on Jet engines with certain stainless connectors. Not repairable and invariably means a new pipe and adapter. It’s almost akin to cold welding. A nickel based lubricant can be used on the threads prior to use but only if that component is allowed to have a lubricant used in that system.
