I bought some recently, and wanted to make a wing bolt. I decided to
MIG the nuts onto some threaded rod. They simply burnt up and melted!
What the heck are they making them of?

Likely a zinc alloy.

Potmetal wingnuts. Good grief! Better bring a magnet next time you
buy bolts at that store, should you choose to ever return.

Ah, but then how will you know they're potmetal and not stainless or
titanium, eh?

Oh, golly, you're right: the magnet won't suffice. Stainless is
easily discernable from potmetal by color, magnet tells the tale of
whether the non-stainless part is potmetal or zinc-plated steel, but
titanium wingnuts would cause some confusion. Don'cha hate it when
careless shoppers get the titanium wingnuts mixed up in the bin with
the potmetal wingnuts?

I'm glad you're the one who said it. g

If you want to use the pot metal nuts, just soft solder them with a
propane torch. The joint will be stronger than the pot metal. G

Just think of them as sacrificial parts to prevent overtorqing and
stripping of the threaded pieces they are screwed onto.

Yes, that's often an issue with me when I visit the local feed store for
wingnuts. Older potmetal is very hard to tell from titanium. I always
bring a pair of vice grips to the store and twist on the wings: if you
can bend the little wings into a pretzel shape and have them spring back
you know it's titanium. If they break then just kinda kick them under
the shelf.

Just ask the guy for some of the copper sulfate they use for control
of aphids, cabbage worms, adult fungus gnats, mealybugs, mites and
thrips. A drop of copper sulfate solution will make a black spot on
potmetal, has no effect on aluminum or titanium.

I agree. Treat with caution! It was only Bunnings "where lower pricees
are only the beginning" (followed by breaking and returning ghe
goods....) G

I reckon these would prevent damage to your _fingers_ ! G

Now another chemical to carry around in a ring on a finger. Hum - might
have to develop a test kit (like pools/spa's testing for chemicals) to test
metals at the scrap yard and the metal stores :-)

Hey, publish what you have so far, why doncha?

A 2% solution of silver nitrate is supposedly used to detect manganize
bronze (Drop turns the metal grey); to sort aluminum from magnesium
(Drop turns magnesium black, does not affect aluminum).
