What is the difference between a Phillips screw and a slotted screw?

I believe that everyone will have a Phillips screwdriver and a slotted screwdriver at home. These two screwdriver tools are specially used to remove and install the Phillips screw and the slotted screw.

So what is the difference between a slotted screw and a Phillips screw? Is it just the groove? Slotted screws appeared early on screw fasteners, and they are widely used. With the continuous development of the industrial age, Phillips screws are more common at present, mainly because when we use a screwdriver to tighten the slotted screws, the grooves are deflected in the lateral direction, and the slotted screws are easy to damage, etc. When the screw is used with a Phillips screwdriver, when the pressure applied from the top to the top is too small, the screwdriver will fall off the screw. In this case, the groove on the screw head may also be damaged. Compared with the word groove shape, because the contact area between the screwdriver and the groove is larger, it is relatively stable.

In automatic assembly factories and other occasions, the use of magnetic force to make the screwdriver and the Phillips screw contact each other, and the scene of automatically tightening the screw is very common. In this case, using cross-slot screws for fixed installation is more accurate than using slotted screws for installation.
