One problem is, tools change. Sears may change manufacturers. I've got some Sears phillips heads that are fairly recent and they don't fit the screws worth a ****. Now, I've been using Phillips a LONG time. Since I was a kid. My Dad got ahold of me early and explained Phillips sizes. And I had my first hammer impact for working on a Honda, the summer of 66 when I graduated high school. So I KNOW about bad, good, and excellent fit with drivers and screws.
(For those that don't, a really good screw with no damage or dirt in the head, and a really well made driver/ bit, you can hang the screw off the bottom of the driver and it may not fall. And I am not talking magnetic, either)
