There are three types of screw heads (that I know of). They are Phillips, Robertson, and Flat.
I don't know which ones are which.
Hubby just asks for a star, square or straight when he sends me to fetch a screw driver because I can never keep Phillips or Robertson straight.
The big question I keep asking is
"WHY ARE THERE THREE DIFFERENT HEADS? CAN'T MAKE UP YOUR MIND OR WHAT?"
Anyway, i could not find a Flat head screw which is the reason for the title.
I've also wondered why there are different types of heads. I didn't know that the square one was known as a Robertson. I'm sure that I've heard it referred to something else (which has totally slipped my mind).
Thank you!
