Got one of these
https://www.dropbox.com/s/0mcpg949t9..._2208.JPG?dl=0
with a badly damaged philips screw head which I can't get out of
here.
https://youtu.be/XlYNf101RJ0?t=56
The thing is entirely plastic in two parts. I don't care about
wrecking
the
whole screw and what it goes into because I am happy to replace it.
I'd normally just grab the head with some mole grips etc but
cant get the screw unscrewed enough to get a grip on the head,
No easy access to cut a slot in the head and use a flat screw
driver.
Guess it might be feasible with a dremel with a cutting disk. I
have
both.
My initial thought was a screw extractor/easy out but the don't
really
go small enough. The threaded part is only 5.5mm thick. The
smallest
screw extractor is listed as 3mm which might well work with a hole
drilled into where the philips slots used to be.
The other possibility is to glue a plastic rod to the head but I
don't
have a rod of the same plastic and there is no obvious way to work
out what the plastic is to order a rod of the same plastic and
glue.
Is one particular type of plastic normally used on those things ?
I guess superglue and metal rod might work.
Any other alternative I might be having a brain fart about before
I order the smallest screw extractor ?
Not urgent, there is some problem with the windscreen washer
bottle that means it holds very little water but its fine to do
without a washer for a month or two while the extractor arrives.
Jam a small screwdriver or pick under the screw head while turning
the
screw
or do a reacharound and clip it off with a dyke.
You do not NEED to thread it out. Just get a pick under the head and
pry it out. They are not threaded in at the factory - they are
inserted like a "push pin"
These ones arent, what the screw screws into is threaded at the
screw head end and head of the screw is recessed into that so
you cant just cut the head off and drive the body of the screw
thru with a drift.
And the screw wasn't driven in either, the whole thing
goes thru an 8mm hole in a small tab in the body metal
of the front quarter guard and that doesn't have the
strength to retain the outer while you drive the screw
in when the car was made. Its clearly screwed in.
Trust me -
No thanks.
I've installed and removed hundreds of them
Not in this car in this position in the car you havent.
and the way they go in is put the screwdriver tip into the philips
recess on the "screw" and swat the end of the screwdriver.
Not possible in this case because that would bend the
small metal tab that the thing the screw screws into
goes into. And no way to put anything behind that
tab to stop it being bent because that is behind the
plastic cover panel that the device hold onto the car.
Mabe half a turn at the end to snug it up. Trying
to tighten them too much strips the head out.
Doesn't take much to pull the threaded portion out
There is when the screw head is recessed
and the philips socket is damaged enough
so it isnt possible to screw it out even a little.
but easier to just drill the head off and
drive it through with a pin-punch.
That wont work either, because again, that will just bend
the small metal tab that the whole thing goes into.
With the "screw" out of it, it pulls right out.
Yes.
We called them "scrivets"
Yes, but they arent all identical on the question
of whether the screw screws in or is punched in.
What are your qualifications to question how they work
Don't need any qualifications for something as basic as that.
when you have to ask about using an easy out to remove them????
I didn't have to, I chose to, in case someone could
come up with an easier way of getting it out.
I am a mechanic with 50years experience,including installing
and removing them in the very position and application you
reference - just not on Mitto****ty cars. On Toyotas and
Nissans and Mazdas - yes On Chevys and Fords too.
But who didn't even notice that the screw is threaded and has
a philips head on it. There is no point in either if its just driven
in instead of screwed in. And you clearly have no idea about
the metal tab that it goes into which would just bend if it was
driven in instead of screwed in. And you don't realise that
there is no way to get a jaw around it to force it in that way
because the inner jaw can't get past the cover that I am
removing to get to the windscreen washer bottle.
And it isnt a Mitto****ty car either. No warranty claims what
so ever in the 5 year warranty and this is the only potential
failure in the 13 years I have had it since new either.
The "nut" prtion is not solid. It has "fingers" that
spread when you force the threaded pin in..
Yes.
Knock the head off
Not possible, its recessed.
and punch it through.
That's going to bend the metal tab the whole thing goes into.
and wont see the SCREW driven thru. It needs to come out the
way it went in, which is why an extractor likely will work.
You have nothing to loose by trying. The metal tab is a lot
stronger than the threads on the screw portion of your "scrivet"
Not in bending it isnt.
- even on a Mitso****ty. If the tab bends a little,
just straighten it out with your fingers afterwards.
It wont just bend a little.
Look at https://www.comdir.co.uk/scrivets-flush-head-type.html
That is different to this one.

Doesn't work.

Als see: https://www.youtube.com/watch?v=eZKcKJ50Xdw
and the installer tool designed to push in the "screw"
https://www.assytool.com/sp-scrivet.php
Mine doesn't pull out as easily as that one and I can
see that by trying to push out the screw on the one that
I have remove because its philips head isnt wrecked.
After playing with the undamaged one that screwed out
fine, it turns out that it does in fact push in fine until the
head stops it going in any further. And with that one
lose it does in fact push out fine when you push on the
inner end of the screw. And with it half unscrewed, you
can in fact pull it out with your fingers.
But with the damaged one it isnt that easy to get
it out a little bit so you can grip the head with a
pair of pliers and pull it out that way but it likely
will be possible to leaver the head up enough
with a flat screwdriver to be able to grip the
head with a pair of pliers.
Yes, drilling the head off and pushing the body
of the screw thru would work but harder to do
to drill the head off because of the limited
distance from the head to the ground even
with the car on the jack stands.
A hot flat screwdriver should work to get a grip
on the head to unscrew it.
I don't have any drywall screws handy.
I havent actually tried getting it out yet, still botting
the 9 brew beer brewing run and doing other stuff.
Likely will try it on Tuesday.
Thanks for these links, it did get me fiddling with the
loose good one.
also see step 3 in :
https://www.carid.com/images/trailfx...structions.pdf
and https://www.youtube.com/watch?v=oUECZAc1B-I
That doesn't work with mine because you cant get the
screw unscrewed enough to get the pliers under the head.
Also see https://www.youtube.com/watch?v=T1PZzACBiXw
That one clearly shows that it is a screw and if its undamaged
will screw out fine like my other one did, the one in the photo.
And that one goes into a hole in the metal, mine doesn't. And mine
doesn't push in on the one I removed like this one does even if you
put it in a hole in a metal plate, it needs to be screwed in because
it's a much tighter fit into the 'nut' than that one in the video.
And with mine you can chisel the head off either because
the whole thing is recessed into the plastic cover that it
retains, it isnt proud like it is in that youtube.
Or watch this guy fight with one:

That's the same video.
Or you can go nuts like this guy -
