Tips for choosing a precision screwdriver set

When performing microscopic and precise work with components and parts for fastening, a specialized sample of screwdrivers is used, which is called a precision screwdriver. This is a toolkit with a very precise sting, sharpened to the utmost proportion to the small heads of screws and other connecting elements. In this publication, we will talk about what this toolkit is, as well as what you need to pay attention to when purchasing it.

This type of screwdriver is used when installing or disconnecting small devices and elements - small household appliances, various devices, for example, watches or cell phones, cameras and pocket PCs, laptops, tablets, game consoles and other types of equipment. Basically, in any service for the repair of such equipment, there is certainly a similar screwdriver, or rather, a set of precision screwdrivers. Since any device can use a different type and size of the nozzle - it can be a straight groove or a cruciform groove, star-shaped grooves, and the like. Therefore, proper screwdrivers are required to handle such components. This means that it is quite practical to keep just such a kit on hand. If we talk about the types and sizes of elements, then there are options for the forms of screwdrivers presented below:

• flat - a sting with a straight slot (groove);
• cruciform groove;
• star-shaped groove;
• 6-sided groove;
• specialized grooves (Pozidriv and TriWing, and in addition Spanner, and so on).

But, for example, Apple uses specialized, anti-vandal screws that can only be unscrewed with a specialized precision screwdriver, the tip of which has a 5-point sprocket configuration, called Pentalobe.

Of course, like any toolkit, a precision screwdriver must meet certain standards and conditions. So, it is required that the tip and the base of the toolkit be made of high quality material - chrome-vanadium or from the class of carbon and alloy steels. The sting of the fixture must be hardened, since the small dimensions of the grooves are much easier to destroy than the large ones - therefore, hardness and stability are almost the main thing that is required from such tools.

The most basic requirement of a precision screwdriver kit is, in essence, the precision of the instrumentation. So, the tip of a screwdriver must strictly correspond to the dimensions of the fastener. Only in this case is it possible to screw or unscrew the element without damage. For this reason, precision screwdriver kits can sometimes include up to 10-12 attachments, with all sorts of blade sizes and configurations. The more devices there are, the more convenient it will be for the repair procedure, mounting or dismantling of the device.

Before you buy a professional set of screwdrivers for fixing a personal computer, telephone and other equipment, familiarize yourself with the aspects of selection and take note of important tips.

• By purchasing a set of screwdrivers that will be practiced in power work, check the hardening level of the base... If it is very soft, the tool will probably twist during the work. An overly cruel (overheated base) can break even during normal work.

• Be sure to pay attention to the configuration of the baseby the way, regardless of whether you purchase a set of small screwdrivers for a laptop or tools for repairing any household devices. To strengthen the bar, manufacturers usually create a 6-sided or square configuration. Sometimes you come across models with a thickening at the beginning of the handle.

• Power jigs are often equipped with T-handles, which make it possible to tighten the screw with special effort. In order to be able to access difficult areas, make sure that the precision screwdriver set is truncated. Due to this, the length of the handle and the rod will not hinder the work. Long attachments are also needed, since they can tighten the unscrewed screw even in a very remote place.

• Don't forget the tipespecially when purchasing a set of micro screwdrivers. It is great if it is magnetic, so that they can be given the properties of a magnet to small metal elements.

• Take a closer look at the handle of each tool, it should be comfortable and ergonomic. Check that its end is even, without minor defects, otherwise, with active use, you will damage your palm. The length of the handle is also fundamental - a long handle will not be suitable for people with a wide palm and short fingers.

• Select the material of the handle. A plastic handle with longitudinal grooves is considered not a very good option. Cruel material with prolonged and hard work with tools of this kind leads to overwork of the hands and the appearance of corns. If the handle is made of wood, then check the quality of the material processing, so as not to "catch" splinters in the future. Having chosen a rubberized or plastic handle, check that there are no cracks on it - keep in mind that such handles will begin to slip out in wet hands.

• Another criterion for choosing the right kit is the type of coverage. The chrome-plated instrument is short-lived. After the outer layer is broken, the steel is subject to rust formation. The edge of the edge loses its stability and the device begins to slip and sometimes wrinkle in the groove.

• The number of items included. The more items, the better, but this affects the price of the tool. The kit may contain screwdrivers and nozzles of various sizes, so take a closer look at the marking. For example, SL 0.5x4 means that the tip is 0.5 mm thick and 4 mm wide. In addition, the kit can include tools for working with small elements and for high-precision mechanical processes.

• Don't lose sight of the brand name. Popular brands include Xiaomi, Bison, Stayer, Stanley, Sturm, Wera and others.
