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