Today we are talking about the two most popular types of screwdriver. Which is being used in most of our everyday applications, they are the flathead and Phillips.
Flathead
By far the flathead tip which is flat bladed is the best recognized screwdriver tip. People have been using it far longer than the Phillips.
It is used to fasten or loosen screws that have a linear indentation in the top. And to speak the truth it can use for other things other than tightening screws. As a result this is one of the most misused tools, frequently stand-in for any amount of other tools that might be unavailable
They are measured across the tip width in either inches or millimeters. And they are the best in applying torque. One flaw in the flathead screwdriver design is the relative strength of the blade, or bit. Although the flathead version has its inbuilt problems, it is still regard as the default model up to present time.
Phillips
The second most commonly used screwdriver is no doubt the Phillips, which was invented by Henry Phillips in the late 1920s. The Phillips screwdriver, by comparison, is still a rather new tool option.
At foremost look, there is a very distinct major variation amid a flathead and a Phillips. A flathead comes with a single blade tip, and a Phillips comes with two blades forming a cross.
The Phillips screwdriver and its head screws were design to provide a safer alternative to the traditional flathead screwdriver. Due to the fact that it would avert damages caused by over torquing and lessen slippage while using.
This is achieved by having a cross-shaped tip and matching cross-shaped screws with a minor indentation. The Phillips could apply more torque as compare to the flathead without causing damages due to over torquing as the indentations in the screws compelled the blades to slide out before any damages could happen.
They come in an array of sizes and are usually are referred to by number and the width of the tip increases with number. And the most common sizes currently are #0, #1, #2 and #3.
I have covered about the two types of commonly used screwdriver. To conclude the single plus a flathead has over a Phillips is universality. A flathead would work just as well for a Phillips screw and flathead screws.
