in this video I'm going to take a look at how to remove some small rounded off
screws to start off we're going to remove a screw which is a recessed hole
and that has actually been rounded off completely and we can't actually get
that undone and if you try turn it, it's just spinning around on the head
one of the first things you can try is an elastic band this works very well on some damaged screws
simply take the elastic band pull it over the end of the screwdriver bit like
so and in some cases that will actually enable you to grip the screw and
remove it with this example I don't think it's going to work because
it's actually in a recessed hole as well but we will just give that a try
that's not actually doing a great deal so what you can do because the screws
are a lot smaller is you can actually try a latex glove so I'm just going to
take a magnet which is Neodymium I'm just going to place a screwdriver through
that and that will magnetize the end of the driver bit I'm going to rip the thumb off there, put the
screwdriver in there we'll see if that will remove the screw
it does feel like it is undoing there we have actually got the screw out if you
take a look at the end of that you can see that it is quite badly damaged
that's always the easiest option trying an elastic band or a latex glove etc and
also if you've got a magnet that can help to remove the screw from a recessed
hole in this example we have a phone case and a couple of these screws have
been rounded off completely these actually use a 1.5 millimeter hex
key or allen key that is very small and if we use that in some of these we can
actually undo them and remove them again I'll just get the magnets again to pop
that screw out these are so badly stripped that the elastic band method
definitely will not work or the latex glove so with these we're actually going
to use a different technique these are the Trend Micro Grab It bits which are a
type of damaged screw extractor these are designed specifically for use on
small screws like this so what we can do with these is we can take the smallest
size which is that one we could put this into a small drill we can use that end
first to burnish the hole and then we can use that end which is the screw
extractor part and there's every chance that that will undo that screw and pull
it out and actually they are so badly rounded that we don't actually need to
use the burnishing part so I'm just going to put this in the drill I'm
ensuring that the drill is in reverse and I'm also choosing the slowest speed
so I'm now going to get the micro Grab it I'm going to push that into the screw
and I'm gonna slowly try to undo it
and as you can see that works very well indeed you know I just need to remove
that from the end of there and that has gripped it really well
so they are absolutely fantastic and they make this kind of job very easy
indeed another option is to use a left-handed drill bit these actually
work in Reverse so a normal right-handed drill bit turns clockwise these
actually turn and cut anti-clockwise obviously there's gonna be a bit of
swarf this time so I've got the magnet inside of the latex glove that should
collect the majority of this swarf again I want to ensure that the drill is in
reverse and on a slow speed as you can see that actually bit into the screw and
removed it quite easily another thing when you're trying to
remove screws is that sometimes the actual thread on the screw itself is
damaged or the bit that it is screwed into and if that's the case you'll often
find that when you are on screwing it even if the screwdriver head has got
good contact that you can't remove the screw so it's always a good idea in
examples like that to try and get some kind of leverage under the part that you
are removing so for example sometimes you can use your nail
sometimes you might need a bit more leverage using something like that
you simply put that in there lever it up and that can help tremendously when
you're removing some screws especially the threads on the screw are stripped in
this example we've got a couple of T5 screws which are rounded off and that is
the actual driver for them and you can see that these are very small indeed so
there's just not chance at all of us un-doing them the driver just spins around
completely
what you can do with screws like this is you can actually try a piece of tinfoil often
called aluminium foil this is what we use when we are baking etc and sometimes
that will fill the hole enough to enable you to grip it so I'm just going
to put that over the screw and then I'm just going to press down until I find
the hole and then I'm going to try to undo it
and by doing that you'd actually just fill the hole in the screw and that
enabled us to undo it that is very similar to the elastic band or the
latex glove is just something else that you can try if you have a rounded off
screw another thing you can use is super glue or epoxy if you use epoxy it does
take quite a while to go off so I'll just demonstrate this one again as you
can see that just spins around there completely it's not gripping to anything
I'll apply a bit of super glue to the tip of the driver I'll then place that in
there and we'll just give that a couple of minutes so that's been in there for
about a minute and I'll see if we can undo that
and as you can see that works perfectly so that's some of the techniques that
you can use to remove small stripped or rounded screws I hope you found this
