impact screwdriver
 

Harbor Freight sells one of those "tools you put in your toolbox
and only get out rarely when all else has failed." It's called an
impact screwdriver. They've been around forever, and the one I
just got cost less than what I paid for one 55 years ago.

What they are is a very heavy solid steel handle with a coarse
pitched screw thread inside, so to speak. Inside the threaded
area is a mated shaft with reversing toggle, and on the end of the
shaft is a hex holder for various screwdriver bits. The tool is a
heavy duty version of the Yankee drill we all remember. They have
a socket wrench-type of shaft and apparently can also be used on
bolts, but I've never tried that, since I have a pneumatic wrench
that works well. Their best application is in loosening frozen
screws, where an inward application of force and twisting motion
is needed.

To use the impact screwdriver, you place the appropriate bit in
the holder and hold the screwdriver firmly while tapping on it
with a hammer. The impact forces the bit into the screw, helping
to prevent the head from stripping, while the coarse threads make
the bit twist just a tad. Usually, that's enough to break loose a
frozen screw if you're lucky, and you then follow up with a
regular screwdriver to finish the job.

The first one I had I bought as a teen to work on my motorcycle's
engine and had it for around 40 years. During that 40 years, I
probably had to use it a dozen times at the most. However, each
and every time it saved the day for me. The one Harbor Freight
sells appears to be a clone of my old one and I suspect it'll
serve the purpose longer than I'll ever need.

I agree with you that this is a great tool. No batteries or power
required, either. Every toolbox should have one.

Sounds like you have it confused with some other tool, an air impact
tool, maybe?
Had one in my tool box since the 1960's and it was the only thing that
would disassemble the early Honda motorbikes for repair. Worked well
with the retaining screw on many of the import cars brake discs and
drums. We learned to apply Kroil liberally before exceeding the yield
point of the fastener.
Possibly the most under-rated but useful tool around.

Yes. Put it next to the nut breaker. The tool to crack a nut that won't

On a related note, I remember using an impact driver years ago to get

Worked like a charm.

That would be a malfunction between the tool and operator.

It don't happen here...never has.

Tips:

1) Hold your mouth right
2) Bite tongue only as needed
3) Twist tool as needed
4) Get a hammer out

Best $10 you'll ever spend. If you know a tool guy, one of these is a great
stocking stuffer. Like you said, you only need it about once every 1.5
years, but when you do, nothing else will work. If you keep it in the nice
little metal box it comes in, it always looks like new. It does take a
while to learn how to use it, though. And that is to use it FIRST, before
you strip the head off that bolt. One or two smacks, and you're done. Same
for setting a bolt. A couple of smacks, and it's there.

Screwdriver mode? You mean when they have a srewdriver tip in the socket?

The whole point of these things is that they didn't chew the philips screws up.

And one of the tricks is not to twist it all the way before you hit it for tight
screws. That way it applies more force down into the head for the rotational
force it generates, which reduces risk of stripping out the screw head.

These were a requirement for a motorcycle mechanic, as ALL Japanese
motorcycles used phillips oval head screws everywhere. If they were
the least bit tight or stuck, you'd strip out the phillips slot. The
only alternative was an air impact wrench, a 3/8" drive butterfly
model the hands down favorite.

I'd be very leary of a HF driver. It's been my experience that Korean
made drivers are the best, the Japanese made drivers the worst. It's
not the driver at issue here, but the bits. Japanese phillips bits
are like those crappy bits they sell by the gross and lumber yards for
cordless drill guns. They wear out or twist. My Korean phillips bit
looks brand new, 45 yrs later, and I've assembled and disassembled too
many motorcycles to count. Somehow, I don't see Chinese steel hanging
in there for the long haul. Hold out for a Korean driver if you're
going to be doing phillips head screws.

BTW, a 2 lb sledge is perfect for driving:

What they are is a very heavy solid steel handle with a coarse
pitched screw thread inside, so to speak. Inside the threaded
area is a mated shaft with reversing toggle, and on the end of the
shaft is a hex holder for various screwdriver bits. The tool is a
heavy duty version of the Yankee drill we all remember. They have
a socket wrench-type of shaft and apparently can also be used on
bolts, but I've never tried that, since I have a pneumatic wrench
that works well. Their best application is in loosening frozen
screws, where an inward application of force and twisting motion
is needed.

To use the impact screwdriver, you place the appropriate bit in
the holder and hold the screwdriver firmly while tapping on it
with a hammer. The impact forces the bit into the screw, helping
to prevent the head from stripping, while the coarse threads make
the bit twist just a tad. Usually, that's enough to break loose a
frozen screw if you're lucky, and you then follow up with a
regular screwdriver to finish the job.

The first one I had I bought as a teen to work on my motorcycle's
engine and had it for around 40 years. During that 40 years, I
probably had to use it a dozen times at the most. However, each
and every time it saved the day for me. The one Harbor Freight
sells appears to be a clone of my old one and I suspect it'll
serve the purpose longer than I'll ever need.

I dont know what the difference is between Manual Impact and one of
the new 18v impact drivers is, but they are labeled as an Impact
Driver, Some are not big but all major cordless tool makers offer them
and they are cheaper than many drills. I saw at sears several big and
very heavy 24v inpact drivers by maybe Sears and Dewalt that looked
like they could do any job on a car, and there are many more lighter
duty units, lighter than drills for screws. For screws they surpass
drills in heavy work like making decks. Popular Mechanics magazine
just did a review of 9 LiIon Impact Drivers, but not the big ones I
saw at Sears.

I agree with most of this thread except the above "hold the screwdriver
firmly while tapping on it with a hammer".

Tapping it? I hit it with a 2# sledge like notbob mentioned.

The one i have is actually a 3/8" square drive with the hex adapter. I
first bought it when i encountered a camshaft retainer in some v-8 i was
working on that had giant phillips head screws holding it.

Right. They are two very distinct tools that work on two entirely different
principles. Mr. Ransley was in error to compare the two. You MAY be able
to remove some screws with an electric impact, but if it's really in there,
all you will do is either strip it out or break the tip. The shock of the
hammer, coupled with the twist at the moment of shock is what knocks the
fastener loose. If one notices, the bits are black, indicating a hardened
steel. It all happens in an instant, and only happens once per blow. If
you are all lined up, and hit it right, it only takes one to two blows.
What amazed me was the price of these little jewels versus the work they do,
and do well.

It seems to be that the standard statement from anyone who has used a hammer
and impact driver for the first time is, "Aha! Got that sucker." After
that, you can listen to all the falderal you want, and will hear a lot, but
you KNOW what will work to get those BIG suckers out that have been torqued
in purposefully so they will stay. When I ran into my first few before I
got an impact driver, I thought, "How in the world did they get that sucker
in there, and how do I get it out?"

What they are is a very heavy solid steel handle with a coarse
pitched screw thread inside, so to speak. Inside the threaded
area is a mated shaft with reversing toggle, and on the end of the
shaft is a hex holder for various screwdriver bits. The tool is a
heavy duty version of the Yankee drill we all remember. They have
a socket wrench-type of shaft and apparently can also be used on
bolts, but I've never tried that, since I have a pneumatic wrench
that works well. Their best application is in loosening frozen
screws, where an inward application of force and twisting motion
is needed.

To use the impact screwdriver, you place the appropriate bit in
the holder and hold the screwdriver firmly while tapping on it
with a hammer. The impact forces the bit into the screw, helping
to prevent the head from stripping, while the coarse threads make
the bit twist just a tad. Usually, that's enough to break loose a
frozen screw if you're lucky, and you then follow up with a
regular screwdriver to finish the job.

The first one I had I bought as a teen to work on my motorcycle's
engine and had it for around 40 years. During that 40 years, I
probably had to use it a dozen times at the most. However, each
and every time it saved the day for me. The one Harbor Freight
sells appears to be a clone of my old one and I suspect it'll
serve the purpose longer than I'll ever need.

I find they usually break the stud/bolt off.....................Or if
it's in screwdriver mode chew the head up.


Sounds like you have it confused with some other tool, an air impact
tool, maybe?
Had one in my tool box since the 1960's and it was the only thing that
would disassemble the early Honda motorbikes for repair. Worked well
with the retaining screw on many of the import cars brake discs and
drums. We learned to apply Kroil liberally before exceeding the yield
point of the fastener.
Possibly the most under-rated but useful tool around.

Used to be the ONLY thing that would take those humungous short screws out
of starter casings. Boink! Done!




There was also a "Wheel Operated Screwdriver" quite useful for those
flat head slotted starter pole piece screws. I don't know if they are
still in use.

It was like a manual arbor press with a pivoting screwdriver bit turned
by a steering wheel like thing centered around the arbor.

You laid the starter in a V-block, pushed the bit down hard with one
hand on the arbor press handle and then pushed or pulled on the
"steering wheel" with your other hand.

For stuck screws in small portable junk I've jury rigged something like
that by chucking a screwdriver bit in my drill press so I can push down
really hard against the screw head while I pull on the drill press pully
with my left hand. It woilks well.

I too have had an impact screwdriver for maybe 40 years, but it's
screwed up fasteners more often than it's done the job for me. I don't
think about using it much anymore.

Put a screwdriver bit in your impact drill. Same thing.

Wrong.

Agree. Anyone who can say that doesn't have a clue what an impact driver does.



second that. One is totally different than the other.

I have had just the opposite experience. However, I use Kroil or PB Blaster
and let it sit overnight before attacking it. I've never tried it, but with
those penetrants, it might just come out with a regular screwdriver. I've
got a couple of those big mama honkin screwdrivers, but have never had a
lot of luck with stuck screws (machine bolts) with those. My wrists are not
strong enough any more. Just mainly use them on humungous screws or as a
prybar or lever. But don't get TOO energetic.
