Sorry to stir up the list. Just to clarify. My first post was wrong.
THERE IS A DIFFERENCE BETWEEN POSIDRIVE SCREW HEADS AND PHILLIPS! The
"engineer" who mis-identified an "Anti Cam-Out" drive (which is for Phillips
heads) as a posidrive, is actually a Product Manager, not an engineer like I
thought. Another guy here dug out an engineering drawing of a REAL
posidrive and the screw head it mates to and showed me the difference. The
posidrive is as Peter described it earlier and clearly not the same as a
Phillips. Sorry to send out bad info. That'll teach me to research what
I'm talking about! :-)
Regards, Greg (a finance guy who continues to learn more about tools
everday!)
