Hidden possibilities of a regular screwdriver

Everyone probably knows how to use a screwdriver. But even the most common tool has hidden possibilities, about which not everyone guesses. Today we will talk about five simple screwdriver chips.



How to use the screwdriver Optimal length In the farm will suit both shorts and the longest representatives of the screwdriver family. But is there a length of the screwdriver at which working with it becomes most convenient? Turns out there is! Scientists have found that the maximum force will be at the length of the screwdriver rod from 120 to 155 mm.



Recall that in the store the length of the screwdriver rod can be selected, focusing on its number. In accordance with the above table, the most ergonomic in the general case can be considered a screwdriver No. 3.

No. 0 is the diameter of the rod 4 mm with a length of less than 80 mm;
No. 1 - diameter of the rod 5 mm, length from 80 to 100 mm;
No. 2 - diameter of the rod 6 mm, length from 100 to 120 mm;
No. 3 - diameter of the rod 8 mm, length from 120 to 150 mm;
No. 4 is the diameter of the rod 10 mm, length from 150 to 200 mm.

If your screwdriver will have to face serious loads, then pay attention to models equipped with a hexagonal amplifier. Such a hexagon can be grabbed with a key to unscrew the most unruly mess.



Rough processing of metal on slits Manufacturers of quality screwdrivers pay special attention to slits. At the same time, in order to provide a better grip on the screw head, the surface of the slit is deliberately coarsified. And in expensive screwdrivers do spraying of tungsten carbide, providing high hardness and wear resistance.



When buying, pay attention to the color of the tip. If it is darker than the rod, this indicates additional hardening, which will positively affect the ease of operation and service life.

Many people think that the hole in the handle of the screwdriver exists to put a loop into it, which will be put on the hand. Or for hanging a screwdriver on a pin storage system. But in fact, this detail has another useful purpose.



In such a hole, you can insert a special amplifier lever or a rod of another screwdriver to significantly increase the applied force.

It turns out that the selection of the most convenient screwdriver is a purely individual matter. Someone has a wide palm, fingers are short, and someone has a narrow one with long fingers. In each of these cases, the handles need different: longer or shorter, larger or smaller diameter. Therefore, in England there is an enterprise that produces a handle under the hand of the future owner.



Phere and the handle. It’s no secret that covering the handle is also important. It is very important that it gives a reliable grip, not allowing the hand to slip. It is noted that the best grip provides the connection of fragments of hard and soft material. In this case, the protrusions should not be too large (no more than 0.5 mm), otherwise they can rub calluses.
