I've always assumed that with pozislot screw it meant you could use either
screwdriver.. Is there realy a special screwdriver?

these ones on ebay say pozi slot
but they dont look like it on zooming in

https://www.ebay.co.uk/itm/1-Piece-1...AhHd V4vUyyZg

- symbol seems to mean flathead
+ symbol seems to mean phillips
are there symbols for pozidrive and pozislot

DIYwiki says:
"Pozislot heads will accept both pozi and slot screwdrivers."
http://wiki.diyfaq.org.uk/index.php/Screws#Pozislot

but one of mine got broken when girlfriend decided to use it somewhere
and now i'm messing up pozislot screwheads in electrical sockets...

PS lots of screw types at:

(but not pozislot)

Most cross-head screws on electrical items are Phillips, my old VDE set only has Phillips or flat although having said that the torque screwdriver VDE set comes with both Phillips and Pozidrive as well as flat.

MK use pozidrive as does Wylex and, ISTR, Hager. Don't know about others

I'd doubt if any UK wiring accessories use Philips head. That's a US thing.

I was surprised to discover recently that the standard has nothing to do
with the Dutch firm of a similar name, but is an American standard.

So:
1. Someone thinks a that will take any kind of driver is a good idea
2. The resulting design doesn't work well with any driver.
3. Driver designed for screws that are a supposed to be a universal fit
but are in fact a poor compromise.

there are loads of types. Ain't life fun. In the soviet union there'd be one type and that would be it. But it would be a poor quality outdated type & everyone would hate it.

It gets worse. I needed to open a Sony TV once and eventually found a weird
tool that seemed to be a cross between a screwdriver and a socket with a pip
in the middle to take the self tapping screws out to merely put in a fuse
which had corroded and thus gone O/C.
I know many companies feel the whole of the public are stupid but the rar
is plastered with warnings about don't open no customer serviceable parts
inside, danger high voltage, so really!

Well I do not know, but I used to use a power supply of the variable kind
bought from Tandy. It was in fact very good. Once again an internal fuse
died, and it was only then I discovered some nut has in fact riveted the top
of the case to the bottom, and I had to drill them out just to put a new
fuse inside. There are some strange things and ideas in this world, I have
come to accept this as normal.
Take the instance of the humble telescopic aerial on a radio. On one very
well known model with a G at both ends of its name, after a year or so, the
mounting for the aerial would pull out of the set before the full length
was untelescoped. On examination, the only thing holding it in was a tiny
groove in the aerial, and a sprung clip that was on the outside of its
socket in which it rotated. The clip simply did not have enough spring in it
to stop the thing slipping over the top of the tiny slot as it wore.


Designers decisions on things are sometimes a little odd, or is it that
somebody trying to reduce costs or make health and safety decisions simple
intervenes and we end up with the resultant screw, screwdriver or other
mechanical part.
Come to think of it, My Sub Woofer died one day, and as I now cannot see to
fix such things, the chap who did told me that in fact the bridge rectifier
had died. He said it was a model which was only rated just above the mean
current of the unit, but whenever it was turned on, merely charging up the
capacitors overran it, and it was just going to go in the end. He had thus
had to fit a bigger one, which of course did not fit the pcb holes and had
to be mounted differently. However it has been very good otherwise, and the
rest of the design is good. Another case of penny pinching by a person who
does not know about surges in current.

"I'd rather die of exhaustion than die of boredom" Thomas Carlyle

In the old days, the tv factory used self tapping screws and air driven
screwdrivers to fit them They were more or less socket hex type heads, but
many of the screws used for parts designed to be removed to get PCBs out or
to change settings or valves had also a pozi or Philips head inside the hex
outside. I even saw some with an ordinary slot which broke through the hex
part, but these did tend to fall to bits on insert since the slot
compressed and the drive slipped.
Even so trying to remove any of these in the filled with a screwdriver was
almost impossible due to the torque used to put them in and most engineers
had a socket set with them. Perhaps not as safe as an insulated screwdriver
around CRTs and capacitors that might still hold a charge, but I never
heard of a fatality!

I don’t buy that. All power diodes have much higher surge ratings than the
continuous rating.

All the ones I remember - mainly on Bush sets - didn't have
any provision for screwdriver removal at all.

Even so trying to remove any of these in the filled with a screwdriver was
almost impossible due to the torque used to put them in and most engineers
had a socket set with them.

Yes - the hex heads had rounded corners between the flats and
the flats sloped slightly - obviously intended for the tool
that they were fitted with to mate with them as quickly as
possible. Thus attempting to use pliers to remove them was
usually impossible as closing the jaws just fired them off the
sloping flats!

That's my take on it too. However I do think that it's rather a bad
idea as neither PoziDriv nor an ordinary slotted screwdriver fits very
well. A Pozi is slightly better and has the advantage of being easier
to locate in the screw but I'd still really prefer *either* slotted
*or* Pozi.
