Can You Describe What This Is/Was Accurately?

Attempt to fix a gas line gone wrong!

A jar of coffee after being microwaved

Coffee was made a tad too strong and solidified

Love the comments up to now, all wrong of course, but all funny! Just as I was hoping.....

It will give you all a laugh at my expense I feel in the end!!!

That is one ugly urinal valve, Andy! psss on it, just tell us.

Seriously, I think it might be some sort of torque coupling device that was terribly underated, or over-driven, then seized up when the bearings upstream went south for the winter.

Del has already posted exactly what it is.....yesterday I believe.....

But thanks for having a go!!

someone's poor attempt at making a custom acorn nut.

Seeing that this is sitting on top of a bed, could this be part of the bed frame? Possibly the base of one of the legs.

That's not a bed, that's a paper towel.

Looks like it was the top of something. Perhaps a wooden 'cork' to some kind of container?

Or maybe an old tap handle for dispensing beer?

Is it this guys' NUTS?

It looks like two nuts welded together on a bolt maybe to facilitate removal of the bolt?

Maybe a shock absorber mount?

Best answer to date, but still wrong.....Also the first one that was not funny!!

Looks like some type of shock isolator.

I don't know what that is, but I bet I can guess your second problem. After you picked that up off that white table cloth(?) or doily (?) or whatever, I bet you had a nasty black spot to remove.

It is a thread die welded to two nuts to chase the threads on a plug.

Looks like the remains of a compression fit finial from an iron bed post.

Previously chrome covered lug nut? Had to rip the chrome cover off just to get the lug nut off?

Closest, but still no cigar.....

Looks like a base for a table lamp turned upside down that caugt fire.

Perfect answer, well done!!

That was it.....

The nuts were damaged the year before last by the tyre company that I previously used, I forgot they were in the car, I had meant to throw them away.

My son-in-law found them and used them again!!! They were only damaged in the "undo" direction, not the doing up direction!!

I managed to get 3 off, but the last one was really difficult, I had two gos with two M20 nuts, did not work/weld properly.

Then I had a friend cut the thread out of both nuts to give more welding room. It went a tiny bit off straight, but still allowed the nut to be removed.....

Big sighs of relief all round!!

Thanks to everyone who commented, especially to "Del the first!"

And thanks for all the funny posts as well....Really great Guys.

Jam nuts with too much jam?

Welding class fail?

The lower rubber/washer looks a lot like an expansion plug.......

Winnie the Pooh's honey jar, turned upside down, to drain the last drop?

I have heard that an exclamation mark can be used as a welding rod in a pinch!

Two nuts that have become securely attached because of bad behavior...Bonnie and Clyde syndrome...

Its a decorative, vintage curtain rod end, standing on a paper towel.

The result of the FLASH, exceeding the speed of sound?

Constipation?

Seriously?

It looks like a coupling or bearing race extractor for a frozen spline coupling or bearing race,where the nut is welded to the frozen part and used as part of gear puller,or pusher.Thread rod into nut,and extract part.

Just to give you a slightly better idea of what it was, check here:-

This is the original box.

This is one of the "least" damaged ones that I managed to get off without using the welder!!

Here is another photo of the problem nut (not me!!):-

The white piece of "lace" is actually a piece of paper kitchen roll, that I use for anything thats dirty and/or needs cleaning!!!

Be careful now and do not speed on the autobahn!!! your wheel bearings have received electric currents that will have damaged them!!

Or perhaps not.....

The ground was placed ONLY on the two nuts for that reason...the bearings therefore had no current through them.

I believe they are fine.

I used two nuts also because of the depth of the recess, so that I could get a spanner/wrench on the last half of the second nut....

It worked out fine....

Thanks for your comments, that will alert others here from making such an error....e.g. never let the welding current pass through sensitive bits!!
