at my last job I took hardrives and opticals out of MBP's daily. About a dozen or two a week. I never stripped screw one. We had the garden variety tools you get at Home Depot, Radio shack etc. Well I had a couple Wiha, and my Japanese tools. But the workbench had crap tools. They cant be tightened down too hard because, yes, they are cheap screws. If you hurry and arent sure you have a good lock when working on these they do strip.
about craftsman, once aupon a time they made the best tools you could buy. I still have craftsman screwdrivers that are dozens of years old. I have seen old craftsman tools in workshops that are 50 years old.
However they are owned by the same guys that own Kmart and OSH now. Not all craftsman has a lifetime warranty. Caveat Emptor.
