Penetration Testing
Penetration testing is a particularly challenging effort. It is a time
consuming process, because it is necessary to fabricate bolted assemblies
and to let them weather naturally for a period of time that is sufficient to
generate a frozen fastener.
Typical
Bolted Assembly in New Condition
The
following procedure was used to perform the penetration test:
1.
A 3/8-16 coarse thread steel nut was bolted to an steel bolt
with 35-foot pounds of torque.
2.
The bolted assembly was allowed to weather for
eight months. A picture of the weathering setup is presented below.
3.
A randomly selected bolted assembly was placed in
a rigid socket.
4.
The bolted coupon was pre-loaded with 40
foot-pounds of torque using a digital electronic torque wrench.
5.
One of the following penetrating oils was applied
to the frozen fastener:
a.
TC-11
b.
WD-40®
c.
Discontinued Product
d.
Discontinued Product
e.
PB™ Blaster®
6.
The amount of time required for the penetrant to
un-freeze the fastener was measured with a stopwatch. Un-freezing was indicated by a drop in the torque reading.
7.
This process was repeated three times for all five
products.
The
penetration test results are presented below.
The table indicates that TC-11 offers the best
penetrating oil performance of any product on the market.
Typical TC-11 penetrating oil experiences are
presented below:
After trying everything from
heat, a large hammer, WD-40®,
pullers, absolutely everything, this flywheel would not come off. I was afraid
that I was going to have to cut it off and buy a new flywheel and crankshaft.
That
would have set me back a little over $900. But as soon as I thought my luck was
gone, TC-11®
to the rescue. I heard about it, thought about it, bought it. For the $10 at a
local ace hardware store it saved me a fortune. Thank you. Danny Walton
"TC-11 can
un-freeze fasteners that I would consider to be hopeless. I was very skeptical
when I first heard about TC-11, but when I saw TC-11 free heavily rusted bolts
in a matter or seconds I was convinced": Colonel Julius Yucker, United States
Air Force (Retired).
We had a customer doing repairs who had a corner crimper that kept jamming up on him. He had to apply a lot of pressure when trying to crimp corners. He came in and asked for a lubricant. We gave him TC-11 and the tool was miraculously repaired. It worked like a charm. We had a guy come in recently who noticed another lubricant we have in stock and we suggested he go for the TC-11 instead. It's not just a lubricant, it also prevents corrosion. We suggest it to anyone who comes in looking for any type of lubricant or corrosion inhibitor.

The lubricants we sell are not penetrants like TC-11. The first time I bought it, I brought in a couple of cases. Now I am buying five or six cases at a time. When you have fittings that are rusted and you can't get them apart, TC-11 is the perfect solution. I tried TC-11 myself here in the store. I couldn't get a stem out of a handle, so I sprayed the inside of the handle and it popped right loose after I let it soak in TC-11. Then I suggested it to a plumber who couldn't get his fittings apart. The stuff just broke right apart. I really think it's a great product. I have even given it to family members to use. It is ideal for lubricating parts and to keep pieces from getting rusty and squeaking.

The first time I used TC-11, I was working on my backyard patio cover. I had a nut and bolt on a bracket that were very heavily corroded. I couldn't break it free dry, but as soon as I used TC-11 it came right apart. I use TC-11 on my boat to spray down the electrical connections and the motor. I have also given TC-11 to a local engine shop.
