Default Why aren't all screws pozidrive?

I go out of my way to get pozidrive screws - what's the big idea with people still using straight ones? Eg in sockets.

Pozidrive selfcentres, and doesn't slip out. And I find it's less likely to burr.

Yes torx would be even better, but pozidrive is a start.

It's an age-old truism. Men will quickly fall asleep after having sex.
And I know why, too.
It's because they've been up half the night begging for it.

I was attempting to fit a couple of cheap "made in China" TV sockets
today. In each socket, 4 screws in total and 3 different styles of cross
heads.

Builders in these parts seem to be adopting screws with a square hole
(don't know what they're called). They allow very high torque to be
applied.

Is the shaft of the screw equally strong? I've snapped screws by applying too much torque.

Oh kind of, it's an age thing and I'm young enough to remember slotted
but it's a bit prissy (in me too).

Torx (or less so Allen) look better than than slotted to me, although
it's a bit context dependent.

Yes, they don't seem very common here - it's all Phillips for normal
work, and Robertson or Torx for anything that needs something a bit more
heavy-duty. Or at least, that's what I've found on the DIY side of
things, anyway.

It makes sense to me though - there's no point throwing another standard
into the pot when what you have covers all bases.

Reed and Prince is one sufficiently different (thinner) from a
Philip's to warrant a seperate driver and there was another which was
like the pozi dimensionally but without the gripper and this could be
made from a Philip's driver by filing back.
I came across another simple cross head "common" design in electrical
and cabinet work in which the blade thickness of the driver narrowed
to the edge of the screw head but can't remenber the name of this one
either.

no extra x so they they be phillips ... yet angle is wrong and Phillipos
drivers simply cam out.


Sometimes it's just a truncated philips head that is required, touch
the end of the driver with a grinder.

A straight screwdriver can be sharpened forever.
Pozidrive a couple of times if you're careful.

Pozidrive is only practcal on hardened screws.

The head on pozidrive is quite easy to chew up too.

Screws on electrical terminals generally have slotted heads. Perhaps

Sacrificial screwdriver method used here. Heat up the end of the
screwdriver in a flame then apply to slot or crosshead and the paint

Slotted screws are not easy to use when 'on site' you are using an
electric screwdriver/drill to insert them.

I'm lead to believe that that type of screw head has been in use
across the pond since well before the war. We had a set of dining
table chairs that were pre-war according to the family source, that
had screws like that. The age was backed up by the fact that they
were glued with hide glue. I had to make up a tool to take the screws
out when maintenance was called for.

Pozidrive selfcentres, and doesn't slip out. And I find it's less
likely to burr.

Yes torx would be even better, but pozidrive is a start.

Steel poles? Concrete pillars? Or Polish? If so what flavour of polish?

I was attempting to fit a couple of cheap "made in China" TV sockets
today. In each socket, 4 screws in total and 3 different styles of cross
heads.

Designed by someone who has never had to fix 6/7mm coax cable to a
wall socket.


It's easier if you take the wall away.


The original task may become easier, but now you have a wall replacement job.

The head on pozidrive is quite easy to chew up too.


When using quality screws and bits/screwdriver of the correct size, they
do not chew up.


That's only because you hacksaw a slot in them so that you can use your
blunt penknife.


Alas many modern screws are case hardened, and so damn hard to cut a
slot in... (small abrasive wheel in a dremmel style tool will do it though)

Screws on electrical terminals generally have slotted heads. Perhaps
someone can explain why. Similarly they generally have very fine threads
- I don't know whether there's a connection g.


The fine threads I can understand - they move slower per turn, so presumably make a better contact.

But this has nothing to do with the shape of the head. I'd much prefer not to have my screwdriver slip off the screw and onto a live wire....

Even more annoying ius when they are cross haed of inderterminate type ...
no extra x so they they be phillips ... yet angle is wrong and Phillipos
drivers simply cam out.


I just look at the angle of the screw and select the correct driver. You need good eyesight like me though.

As to why we won;t go all Pozi ... simple, US uses choses not to use Pozi.


I look forward to them becoming a third world country.
