Hello, John Talley here with partzilla.com.
Today we're going to spend a little bit of time talking about thread lockers--
looking at the Permatex line in particular-- also
help you determine which thread locker is going to be best for your application.
Now if you go and do a little bit of research on these, it's almost
overwhelming. I mean, the amount and the different types of
thread lockers that are available it can be a little bit of a daunting
task, and what you're going to find is that there's a lot more out there
than just your typical blue and red thread locker. They make several
different formulas that can address just about every single application that
you're going to run into no matter what you're working on.
As a general rule of thumb, you cannot go wrong by using
thread locker on just every single bolt on your machine, and there's a couple of
advantages other than just holding the nut or bolt in place. But because
this is an anaerobic type sealant, it actually forces air out
and seals in the absence of air. And what that means is
when you actually put it on the threads, it does not activate
until it is actually put together. At that point,
it forces out all the air and then cures. Now here's the other side effect of that:
well guess what? If it's forced out all the air,
that's going to keep corrosion from actually working its way into the
threads and freezing up that particular fastener. Now if you're
in the marine industry, that is invaluable because that
is the harshest environment that I can think of.
Saltwater? It doesn't get much worse than that.
Also it makes it easier to assemble because it acts as a lubrication as
you're putting it together. What I'm going to do now is just walk
you through a flow chart where you can answer simple questions
that will guide you to which product is going to fit best
for your application. The first question you need to ask is,
can you apply this before assembly? In some cases you may have already had
something that's put together that you want to make sure that it holds.
They actually have a product that addresses this particular application.
You actually put it at the top of the threads and it will wick
down into the threads and then actually seal it up
and hold it in place. Now the majority of the thread lockers out there,
they're designed to be applied before you actually assemble it. The next
question we need to answer is the diameter of the thread that we're
talking about. Is it a large diameter, you know, one inch or greater? Or is it a
smaller diameter? Now there is some overlap and there is
no absolute here but this is mainly just a guide
to tell you which way to go. Now if it's a really small,
fine thread, let's say anywhere from a quarter up to a half inch even up to
three quarters, then you want to look into the blue
thread lockers. Your application for the blue thread locker would
typically be for valve cover bolts, water pump bolts, oil pan bolts,
rocker arm adjustment nuts, carburetor studs,
shift lever, brake caliper parts. Typically for bolts that you know you're
going to have to hold in place, but there's a high probability that you're
going to have to pull them out three or four times during the life of
the vehicle, and we want to do that with the minimum
amount of effort. You don't want to have to bring out a heat gun to actually
break it down. Next let's look at your applications for
bolts that may go from half inch, three quarters an inch, and even larger
and they're going to be in a high strength application and/or a
high temperature. That is where you're going to want to
use something in the red threadlocker line.
The red threadlocker series-- particularly-- I love using the red
on the inside of an engine. That way, I know
whatever nut or bolt that I've put in there it's going to get held in place.
Some of the applications are going to be cylinder block studs,
rocker arm studs, ring gear bolts, frame bolts, shock absorber bolts,
your transmission shaft bolts, camshaft sprocket bolts, your idler bearings.
I mean, you name it. If it's inside of your engine, that's absolutely where you
need to use the high temperature thread locker to make sure that those nuts and
bolts and fasteners stay in place. That is going to be the most
high stressed area on your machine. But let's be honest. Are
you gonna keep eight to ten different thread lockers in your toolbox?
Probably not. My rule of thumb for my toolbox,
I at least have a blue and a red on hand because there is a lot of overlap and
just having those two in your box that will get you through
and get the project done for the day. Listen, if you need these or any other
