Rounded off drain plug

Here’s his test results. My experience is if you were to take those nuts off with a ratchet using any form of oil makes a BIG difference. I doubt there was much rust in the threads. It would have been interesting if he removed the nuts completely.

"Same function"?
You can remove a seriously thread rusted coupling on a 2" dia. piece of galvanized steel water pipe with the Aussie "Best-grip"?
I think I gotta get an Aussie "Best -grip"

I don't see why I wouldn't be able to... along with the 'kit' (4 increasing sizes) I also bought a large one that would handle that size. The gripping principle is similar to that of a pipe-wrench without having to do the 'adjust the jaws' step.

A wee bit of 'your choice' of penetrating spray/oil prior to the job would always help.

The only/largest one (Aussie) that I can find shown on the internet is actually called "Better Grip", and is 16" long.
I think it very unlikely that any 16" long wrench, of any style, would separate an internally rusted coupling from a 2" pipe.
Is there a 24" or 36" long "Better Grip" model?

I just trudged out to the shed and measured the largest one that I bought and, yes, it's the 16". With the jaw fully open (spring loaded/tension) I could attach it to something 2.5". As to if there are larger ones, I don't know as I only purchased the largest that I could imagine ever using and I haven't used the 16" on anything yet. (But I have it! :laughing I have used a couple of the ones in the kit from time to time and they do work as advertised as a wrench/ratchet.

That is a nice looking wrench. Imagine saying schraubenschlüssel just to say wrench. Germans are interesting people, but their word salad bowl overflows.

schraubenschlüsel = wrench, and is composed of the words for "screw key", according to Google Translate.

I'm sure the Germans say it using far less letters.

Any test that rates wd40 as better than kroil....I tend to not believe any of the other results either

 

[mcfarmall]

I agree, LD1. KROIL is effective even on galled stainless steel...if it's not galled too bad. Best stuff I've used in my 28 years of fixing other peoples screw-ups.

FWIW here are the four wrenches that live in a drawer next to my big bench vise - plus the 'bionic' toy I just found in a thrift store to try out.

It is very common to clamp a rusted bolt or something in the bench vise, then reach for one of the four wrenches to get a rusted nut off it.

The bionic toy doesn't go down as small as I expected. Maybe down equal to a half inch wrench. Anything that size and larger that is rusted may not come off with so little leverage. We shall see.
