Acetone/ATF mixture performance report
It's "out there" on the net that a 50/50 mix of Acetone & ATF is frequently effective
at removing fasteners badly corroded in place.
I've used the mix before myself but today I found a fastener situation where it didn't
help in the least. Applying heat didn't help either......
Milspec fastener AN363-524 is a prevailing torque "lock" nut, 5/16-24 in thread. They
are also found in other thread dimensions as well.
I had to cut the locking segments at the top of the nut off very carefully with a Dremel
to remove it, on what I would call, a slightly corroded thread.
This nut was factory installed inside the door of my '48 Ford truck.....
