I decided on cleaning my laptop fans today, which I’ve been procrastinating for about a year now because of this one screw. But I just can’t seem to open this with my screwdriver, since whatever I did back when I last opened it it’s nearly circular now. Is there a way to unscrew this?
Flathead is a description of the head profile, like panhead. Slotted is the screwdriver type that is just a single slot.
It could be a regional thing. Where I’m from a screw with a single straight slot can be called a flathead whether the actual head of the screw is flat or domed.
It gets called that everywhere. Most people never need to know the actual specs for a screw, so language diverges from the classification system.
I usually keep the corrections to myself, but when somebody else is already correcting someone and they say the wrong thing too it becomes hard.
