When a Phillips is not a Phillips!
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.
I didn’t learn any of this watching way too much Handy Manny last week.
phillips and pozidrive are designed to slip under high torque. really annoying chewed heads. grrr
torx heads rule.
Wow. I never though that reading about 25 types of screws with trivial differences could be so much fun. Can’t wait for the sequel.
Andyb, I still prefer the flathead. Can’t find a screwdriver? Use a knife or any other similarly shaped object.
