What is the Difference Between a Flathead and Phillips Screwdriver?
At first glance, the main difference between a flathead screwdriver, or more properly called a slotted screwdriver or flat blade screwdriver, and a Phillips screwdriver should be patently obvious. A flathead screwdriver has a single blade, and a Phillips screwdriver has two blades in the shape of a cross. Attempts to use a flathead screwdriver on a screw designed for a Phillips usually won’t be successful, and a Phillips screwdriver could never be used on a slotted screw. Both are considered “driver” tools, which means they are used to force bolts or screws through various types of material.
