Thanks Mac !

That was very interesting!

I've done my part - I've stripped thousands of the dang things!

I owned my MG for 22 years before I learned about Posidrive screws. Just proves there's always more to learn. And finding Posidrive screwdrivers led to finding Wiha tools. Another thing I learned!

Yeah - it is fascinating to know that Philips screws slip by design. That explains a lot.

Still don't know why Moss doesn't source the posidrive.

Just purchased a #4 Pozi Driver Bit Socket, Drive Size 3/8 Inch from Grainger. It is the only one I have been able to find. They also have a #3.

I picked up a set of #1, #2, and #3 pozi driver heads at Sears last night. No #4s.... :( When I went to pay for them, the sales guy kept trying to tell me I really wanted the torx drivers. Nice.

Why doesn't Moss sell Pozi screwdrivers? Even Pozi bits are nearly impossible to find, but I'd rather have a set of Pozi screwdrivers. I suppose it's because no one makes any? Not that Moss would sell that many, of course.

When I was younger I used to build wooden boats. As an apprentice I got into trouble for ruining a bunch of screws on a piece of work: anybody remember Reed and Prince screws? I had never heard of them either... until then. Don't see them too often but all this talk about unusual crosshead screws reminded me of that. I still have a bunch of Reed and Prince bits somewhere.

Some new electronics use pozi drive screws. The new transponder identifiers for automotive key machines are assembled with pozi drive.

Reed and Prince...the driver's point is sharper and longer. Used almost exclusively in woodworking. Nothing will ruin a Phillips head faster than a R&P driver. And a P driver will cam out qucikly on a R&P screw.

I had a film processor sold by Agfa but made in Denmark that used all Pozi screws.

Pozidrive screws are still in use. I find them quite often on different items I have purchased from furniture to appliances.
