We can thank instructables user arcticpenguin for this excellent explanation of cross-head, cross-point, cruciform, and square drive screws and drivers!
These screw types have a “+” shaped recess on the head and are driven by a cross-head screwdriver, designed originally for use with mass-production mechanical screwing machines. There are a few other recessed drive screws presented that you also want to be aware. So, why all the confusion? Why all the damaged screw heads and drivers? Why is this screw and driver thing so awkward? Read on and be amazed while I unravel the mystery of screw drives and present some you may have never seen.
