Peter, you are absolutely correct and I feel stupid for sending that into
the list before getting a second opinion. By pure coincidence, after I sent
the first email, quite a debate ensued here in the hall over this issue and
it turned out that the drive bits that the first engineer told me were
posidrive were, in-fact Anti Cam Out drive. The second guy showed me a
drawing of the real posidrive along with a drawing of the fastener head and
it is as you said. From now on, I'll research my facts a little more before
I embarrass myself world wide! :) :) On the bright side, I continue to
learn a great deal. Regards, Greg

Greg, with all due respect, this "engineer" is plain wrong. To
consider that
he is in the business of designing tools is certainly amusing among
other
things. A posidrive screw head is designed specifically for a
posidrive bit.
In fact, a posidrive bit does not even properly tighten/loosen a
phillips
screw -- the extra ridges simply don't provide a proper mating of
the two
surfaces.
Take a close look at an unmolested posidrive screw on your car (they
are all
over). It will have four extra (and much smaller) slots at 45
degrees to the
main + of the phillips pattern. If you still have doubts or don't
have any
unmolested screws on your car, go down to a local Volvo dealer and
order the
screws which retain the top cover of the ZS carb. (They stock them
at Volvo
dealers!) and you'll see.
I personally question the knowledge of your workmate on this one.
Please
understand... I mean no offense to anyone -- we are all wrong at
some points
in our lives. I have deliberately replied in private to give you a
chance to
rescind your comments made to the list. They are truly incorrect and
will
undoubtedly result in misguided folks butchering their posidrive
screws with
phillips drivers.
(Just think, would you consider the deformation of a fastener head
during
its installation/removal to be normal? I sure don't)
As I said at the top, with all due respect...Just wanted to set the
record
straight.
