--Winston-- Helix'ed a few Allen wrenches though.
I have had a SHCS cam out as it must have been abused in the past and
the socket was damaged. Tried everything including a lever to force the
bit into the socket but it was always ejected, new sections cut from new
Allen keys no use, hex drive bits no use, Went down the pub that evening
to forget it and came back the next day with a carbide burr in a die
grinder to remove the head, once it was removed the thread unscrewed by
hand as the thread was clean and not binding and could be undone with
your fingers. Not so used to Phillips in the UK as PoziDrive is much
more common. Also would have to check the spelling as the European
Philips maybe confused with phillips, any relation?.



There a LOT of PoziDriv screws used in the US as well, but an amazingly
small number of people who have even heard the name[1], and even fewer
that can identify one. Only 5% of those remaining actually have and use
PoziDriv drivers. At last count, it was me, and four others spread
across all of N America.[2]

PoziDriv bits are included in the HF 100-piece security bit set.
http://www.harborfreight.com/catalog...=security+bits

Also clutch, torx (security and regular), metric and inch allens
(security and regular), torq-set, tri-wing and triple square, flat
blade and security flat blade, all for 9 bux.


That set has been on sale for $5.88 several times this year.



It is a good set.


I have a couple of them.

What good are security screws when anyone can go to HF and get tools for
$5.88 to remove them?


Not all security tools are available to the public. Some I used over
20 years ago still aren't sold without a lot of paperwork. The more
common types are more safety related, to keep general idiots out of
things.



Do you have an example?



A hollow oval head used for CATV equipment. Hamlin used them on
their descramblers. You could get them out with a pair of dykes, but
nor without destroying the screw and damaging the case. Either cost the
customer their account, and they could never get cable service with our
company, anywhere in the US. A list of violators was kept, along with
their personal information for future reference.


A five sided version of an Allen head, with a center pin and used for
wall plates for addressable taps. For that one you had to buy the taps,
controller, wall plates, screws and tools at one time.
