Phillips screwdriver dimensions
If there is a need to fix something, and screws, self-tapping screws or screws act as fasteners, then a screwdriver comes to the rescue. Not everyone has screwdrivers and cordless screwdrivers, but every “real man” has the familiar flat or Phillips screwdrivers. The most common screwdrivers are those with a flat or cross-shaped blade. But these are not all varieties.

Features of Phillips screwdrivers
The Phillips head screwdriver is more popular than all other types. This is what will come in handy if you need to unscrew or, conversely, tighten something in most devices. You don’t have to start disassembling any modern mechanism without a screwdriver of this type.
Its main feature lies in the special shape of the sting, which is a cross. If a similar “Orthodox” slot is found somewhere, then you need to unscrew it with just such a device. 
Reference. A variety of materials are used for the tool handle. It does not slip in the hand, it is easy and comfortable to hold, and there are no unpleasant sensations during prolonged use.
It is logical to assume that the handle of a screwdriver is designed to transmit torque forces to its working area. Handles can have different shapes, sizes, and be made from a variety of materials.
The point here is not only the designer’s idea, but also the fact that each person has a different body structure.One person's hands have wide palms and short fingers, while another has a narrow palm and long fingers. That's why the handles have to be different.
Various materials are used for them. The choice here is purely individual. The main thing is that the instrument fits comfortably in your hand. The end part should not rub your hands during constant use.
Many pens are round in shape, and some of their edges are intentionally ground down. This way the screwdriver holds better on inclined planes. The holes that can be seen at the ends of the handles are used for suspension. You can use it to pick up and hang the instrument.
Most often, handles are made of plastic. But there are options here too. Plastic can be powdered or cast. In the first case, the handle will be hard, but you cannot hit it - it will crack very quickly. Molded plastic is more elastic, but not as hard, and they differ in appearance. Very often the handles are made combined.
At first, the Phillips screwdriver had a more complex shape than its current form. In addition to the cross shape, a cylinder-shaped recess was made in the center. The diameter was about two millimeters and the depth was about three millimeters.
But in practice it turned out that the use of this guide is completely unjustified. As a result, the current form remained. What is so remarkable about the cross shape? It's simple. The screwdriver is securely fixed inside the screw and does not slip anywhere. If you use it correctly, the likelihood of damage to the fasteners is almost zero.
Thanks to the cross-shaped shape, the contact area is doubled. Phillips screwdrivers are called Philips; you can also find an abbreviated version of the name - PH.
Reference. Philips type screwdrivers are not related to the well-known manufacturer of electronic equipment. They are named after the name of the inventor.
What are the sizes of Phillips screwdrivers?
Screwdriver tips vary in size. All of them have certain numbers, by which one can judge the size of the entire instrument as a whole. The smallest size of a Phillips screwdriver is designated 000 (this corresponds to 1.5 millimeters). This size is successfully used when repairing mobile devices or cameras.
Next, you can list the following numbers:
- 00 (from 1.5 to 1.9 millimeters);
- 0 (2 millimeters);
- 1 (from 2.1 to 3 millimeters);
- 2 (from 3.1 to 5 millimeters);
- 3 (from 5.1 to 7 millimeters);
- 4 (from 7.1 millimeters).
The most often in demand is the second model, equipped with a magnetized tip. The largest, naturally, is the fourth number and it is used when working with cars.
The marking tells us not only the size of the tip, but also the diameter of the rod. Accordingly, the higher the marking number, the larger the diameter.
Well, the length is selected depending on the task. If the space is small, it is better to use screwdrivers with short handles. Long screwdrivers allow you to reach something hard to reach.
To make the tool easier to use in the future, you should carefully select the sizes. In order not to buy a new screwdriver every time for certain needs, it is better to immediately purchase a set of tools of different sizes. Then, without a doubt, any fastener will surrender to the mercy of the winner.
