Of special interest to anyone who's Nuts about Bolts:
Penetrating Oils
Machinist's Workshop Mag recently published some information on various penetrating oils that I found very interesting. Some of you might appreciate this.
The magazine reports they tested penetrates for break out torque on rusted nuts.
They are below, as forwarded by an ex-student and professional machinist.
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 oils .......... Average torque load to loosen
*No Oil used .................. 516 pounds
WD-40 ..................... ... 238 pounds
PB Blaster .................... 214 pounds
Liquid Wrench ..............127 pounds
Kano Kroil .................... 106 pounds
ATF*-Acetone mix..........53 pounds *ATF=Automatic Transmission Fluid
The ATF-Acetone mix is a "home brew" mix of 50 - 50 automatic
transmission fluid and acetone. Note this "home brew" released bolts 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 almost as good as "Kroil" For about 20% of the price.
