What is Pozi screw?

That's what you like and what you're used to. Who am I to try to change your
opinion? But, you *are* very much in the minority when it comes to what's
most popular and what contractors like to use.

Over 30 years of personal experience and my knowing a good half dozen

Drywall screws are and always have been in a category of their own.

You're supporting my argument by that statement. I never said there was
anything wrong with Phillips screws, just that most prefer Robertson if
they're available. Try a little experiment and use non-magnetic Robertson
and a non-magnetic Phillips screwdrivers. Put on a screw and shake each one
including turning them down. Almost always the Phillips will drop off first.
It makes plain logical sense what's going to be more popular when they're
examined side by side. It's also a fact that Robertson screwdrivers contact
more screw head surface making them more capable of keeping a screw straight
when driving it in.

Sounds more like very little experience with Robertson screws.

This is not my experience and I have never seen any evidence that
square head is better performing than Phillips. In practice, I find
little difference between the square drive and Phillips in terms of
stripping out. Given the choice, I would pick the Phillips over the
square drive.

SFWIW, most of the S/S fastners already come from India.

A lot of these screw designs come from guys who want to use several
thousand of them per hour via an auto-feed screw machine in mass
production assembly.
Robertsons don't work well in auto-feed. The square drive CAN be
exactly 45 degrees out of place, and the machine will jam.
So, for manual work, square (robbies) it is for me.
But I always have tips and drivers for Pozi as all the euro hinges use
them and a Phillips just plain sucks in a Pozi screw.
McFeely's combos are just fantabulous.

Pozidrive was developed as an improvement on the Phillips or crosshead
screw. However, it is different from Phillips and works better when
used with the correct driver. However, it's main disadvantage is that
it looks like a Phillips screw and many Phillips drives also *fit* the
Pozidrive head. The result is stripped out screw heads. Here is a
more detailed explanation:

One thing I do not deny, is that there are junk Robertson screws on the
market. ~ Maybe more than there are junk Phillips. All things being equal,
if I had to choose between cheap Robertson and cheap Phillips screws, I'd go
for the Phillips every time. Cheap Robertsons don't hold as well and will
strip much easier than the Phillips.

It's too bad that square drive is not common for you. The square drive has
a bigger advantage over Phillips than Phillips has over a Straight blade
screw. With Square Drive, srtipping out is almost unheard of. Additionally
there is a Combo Square drive that lets you use a Phillips or Square drive
driver.

The whole idea of Pozi is that the heads are LESS likely to
strip. Having said that, every screw with a head made from
potmetal strips relatively easily. I'll take a hardened-head
phillips screw over a mild steel pozi any day, but metals being
equal, and the *right* tool being used, pozi is superior.

These [GRK] puppies get my vote. AND, They're CANADIAN!

http://www.grkfasteners.com/en/R4_1_2_information.htm

Note to LEON: Circle Jerk - er-r-r-r - Circle Saw sells them in bulk (~
$7/lb.). Am also seeing a coated variation at the BORGs also with a TORX
drive head. I have even seen them at HD in SS. HD is very proud of the SS.
For the record I have a handful of the 3 inch GRKs that are on their
second set of sawhorses living, for the most part, out behind the garage.
In ten+ years I can count on one hand the number of times I've twisted the
head off a GRK R4.

Well, the heads are easily stripped *if you use a Phillips driver*. Use a
Pozidrive bit and the chances of stripping the head or of the screwdriver
camming out are much smaller.

Over here in the UK Phillips is almost dead, Pozidrive is everywhere (and
is also a Phillips patented design) and square drive screws are a rare
novelty (although well-regarded by people who've used them).

Try using the correct tools.

Where's the evidence for your statement? For example, and I know it's
a slightly different application, if you walk into a Rona or Canadian
Tire looking for drywall screws, you won't find square heads at all -
they're all Phillips! I worked on a large (tens of thousands of
screws) playground project and the screws supplied were Phillips. The
pros on the job bitched and moaned but when the job was done they
begrudgingly admitted that they were not as bad as they thought.

The reason that you don't see square heads on dry wall screws is because
every screw is suppose to slip/cam out when the screw has reached the proper
depth.

Not at all. I am based in Toronto so most of the screws I can readily
buy are Robertson. Now I know Canadians are very proud of Robertson
and promote it wherever and whenever they can - just like Canadian
beer. I have all the correct drivers for my drills and all the
correct screwdrivers. The screws I buy are from all the major
retailers here and a variety of manufacturers. The applications have
been woodworking projects, deck construction, home renovation etc.
Where I have the choice I will reach for the Phillips or the Phillips/
Square combo in preference to the Square.

Your first argument I accept completely - the Robertson drive is much
better at holding the screw than the Phillips, horizontally or
vertically. On your second point, my guess would be that there is
more contact with the Phillips. Anyway, as I work and live here in
Toronto, I will just to learn to embrace and love the Robertson square
drive because that is what is generally available. Maybe if I change
my attitude to it, it will work better for me :)

You're supposed to drive the screws, not drive to India.

Frank

First ran onto these screws about 30 or more years ago. There are
available screwdrivers and tips but the heads of the screws seem to
lack sufficient robustness to take much activity. The heads are easily
stripped.

Some of the PoziDrive screws can accomodate some Phillips tooling and
others simply don't take easily to any tooling. When I have the
opportunity I dump the screws and replace with conventional Phillips
heads. Preferably SS screws.

Funny thing is the Tektronix used them with their test equipment,
oscilloscopes and the like, which gave them a bad name at times.

Hwev you tried a Google search for more information?

Thanks for the info. I currently probably have 3-4,000 square and combo
screws from McFeeley and Kreg. I have had pretty good luck with both
brands. I have regular square drives that have been outside for 15 or so
years with the head facing up. They still are in pretty good shape even
though the heads fill every time it rains.

Torx is a great screw. I recall using them way back in the late 70's when
the automotive industry started converting over.
