Rusted Nuts

Rusted Nuts

Okay, now that the title has caught your eye I’ll start right off the bat saying I have not tried this and, if you do, you do so at your own risk. I’m not a chemist so don’t know if there is any issue with what is noted below.

Alrighty, disclaimer out of the way….

I decided to post this as, for me, I’ll know where I can go to find it should I need it. Or not. My filing system seems to evolve (?) over time.

This was received from a friend via that old arcane method of sharing jokes and other tidbits. That’s right, email. Speaking of which, if you’d like to get alerted when I do take the time to actually post something, just subscribe to my standard RSS Feed or the Email RSS Feed.

The following is the contents of the email with a few editing strokes of the keyboard and formatting changes:

Some of you might appreciate this. For those of you who are mechanically challenged, please forward this to your household repair tech. If you have any input or experience just leave a comment.

Machinist’s Workshop Magazine tested penetrates for break out torque on rusted nuts. They are below, as forwarded by an ex-student and professional machinist, Bud Baker. They arranged a subjective test of all the popular penetrates with the control being the torque required to remove the nut from a “scientifically rusted” environment.

Penetrating OilAverage Loadnone of the above is verified

None 516 pounds
WD-40 238 pounds
PB Blaster 214 pounds
Liquid Wrench 127 pounds
Kano Kroil 106 pounds
ATF-Acetone mix 53 pounds

The ATF-Acetone mix was a “home brew” mix of 50 – 50 automatic transmission fluid and acetone. Note the “home brew” was better than any commercial product in this one particular test. Our local machinist group mixed up a batch and we all now use it with equally good results. Note also that “Liquid Wrench” is about as good as “Kroil” for about 20% of the price.

Hope you found this useful and that you were able to break those old rusty nuts free.
