Hi,
What's wrong with it? Just use correct size good screw driver!

.....and keep your good screwdrivers hidden, before kids or wife use them as chisels or pry tools.

Sure, they work, but a square drive is far superior to hold with a bit.

I think it has to do with quantum mechanics and keeping the world in balance. For every plus screw they make, theres got to be a minus screw to cancel it out. Nature likes things made in pairs. :>)

Holy shit...is this true???

i guess square drive screws have zero charge....
you would think that there would have to be equal numbers of standand and reverse threadhed ones so that spin is conserved as well

I believe that for machine screws, spin conservation is solved by making one nut for every screw.

Perhaps the "extra" nuts that are often included help balance the wood screws. But just in case, I try to run my cordless screwdriver in reverse for a few seconds every day -- otherwise the whole universe could get screwed up.
