So, we are faced with the task: to unscrew the steel bolt from the aluminum crankcase (a very difficult case, since the steel-aluminum pair stick together tightly relative to each other). What is the best way to do this? If it is known in advance that the bolt is badly corroded and unscrewing it with an ordinary wrench will be oh, how difficult it is.

Everything is correct. Such a bolt can only be unscrewed by a blow applied to the bolt in the radial direction or good warm-up. We sweep aside the heating of the bolt immediately, since the area of ​​the bolt head is small and it will be simply unrealistic to warm up the entire body of the bolt, but the necessary blow will be provided by the same impact screwdriver.

First, let’s see what this tool is, so to speak with our own eyes. The complete set of this tool includes: a metal case, six bits for a different slot, an adapter from a square to an internal hexagon. The price of this model of an impact screwdriver is very affordable, of the order: 400 rubles, the quality is quite consistent with the price and level of equipment.

Electronic Indicating Instruments

The modern version of the voltage indicator is an electronic screwdriver with a display, sound and light indicator.

In fact, it is a full-fledged multifunctional voltage indicator, the “little brother” of the multimeter.

The presence of an electric current in the circuit is indicated by a phase indicator light and an audible buzzer.

The voltage value is displayed on the LCD screen.

This instrument is capable of working with AC and DC networks, which makes it suitable for testing networks of vehicles powered by batteries.

As a rule, this option is not common among professional electricians due to the high cost.


Inside the universal indicator screwdrivers there is a microcircuit that will expand the capabilities of the tool.

There is a slider on the body. a switch by means of which the operating mode is selected:

The presence of voltage is signaled by a built-in light.

The presence of voltage is indicated by a light bulb. The mode is characterized by low sensitivity

Non-contact inspection with high sensitivity

The presence of current is signaled by both the light indication and the sound signal.

This mode will allow you to find current-carrying wires even under a layer of plaster.

Such indicator multifunctional screwdrivers are very convenient to use, and most importantly, they are effective.

It should be remembered that the presence of additional elements in the device increases the cost of the tool.

In addition, batteries are used for power supply and must be changed frequently.

With display

In simple indicator screwdrivers equipped with displays, no batteries are used, and the presence of voltage on a phase is indicated by an icon appearing on the LCD screen.

Works by reading the electrostatic field.

Typically, these tools are compact and the body is made of plastic.

Indicator screwdriver types and selection

The indicator screwdriver has several varieties that perform both standard and additional functions, you can learn all the details from this article.

A huge number of household appliances provide comfort in the house, but the use of several powerful consumers at the same time leads to an excessive load on the wiring.

This is fraught with, at least, minor breakdowns, which can be eliminated on their own without resorting to the help of an electrician.

To correctly determine the phase and zero, protecting yourself from electric shock, as well as to correctly connect electrical appliances and troubleshoot the electrical network, an indicator screwdriver is used.

This tool should be kept in every home, because it is easy for them to determine the working phase and zero (by elimination).

In the arsenal of an electrician, such a screwdriver occupies a key place.

Most of the repairs of electrical appliances, equipment and the elimination of faults in the electrical network begin with it.

What is an indicator screwdriver for?

The main purpose of the indicator screwdriver is to check the presence or absence of an active phase in the mains.

Due to this, the process of setting up equipment, repairing electrical circuits and their laying are greatly facilitated.

Using the tool, you can determine the location of the phase and neutral wire breakage yourself, without resorting to the services of an electrician.

The indicator screwdriver ensures safety when working with electricity by detecting the presence of current in the circuit.

It is often indispensable for electrical installation, especially if work is carried out with old wiring, where the phase and neutral wires cannot be visually distinguished (aluminum wires in Khrushchev, for example).

You will also need this tool if you need to replace or install sockets and switches in an existing electrical network.

Interestingly, the indicator can determine the position of the switch (on or off), which allows you to install it on the correct side.

Using modern models with a display in everyday life, you can perform the simplest dialing function of the power supply, which allows you to find out the current voltage, its other parameters.

Still, for a full-fledged work, a normal tester is needed.

Model with neon lamp

A neon tester screwdriver is the simplest probe.

The disadvantage of this contact-type tool is a fairly high voltage indication threshold. from 60V.

Used to determine the phase in the AC circuit.

Not suitable for finding wire breaks.

An indicator screwdriver such as UNO is popular in everyday life. a single-pole voltage indicator, the operating range of which is limited by the upper mark of 500V.

Used when connecting electricity meters, fuses, switches, etc.

The principle of operation of a screwdriver with a neon light is its glow when the tip contacts a current-carrying conductor.

Electricity passes through a resistance resistor and closes on a person with a second contact located at the end.

Simply put, the lamp will light up if you touch the sting to the phase wire, and touch the end contact with your finger, thereby closing the circuit.

With LED

The principle of operation of the indicator with LED does not differ from the options with neon lamps.

But this tool is good because it works great with power grids with a voltage of less than 60V.

The LED indicator screwdriver device includes a self-contained power supply and a bipolar transistor, making this tool multifunctional in all its simplicity.

Allows you to determine the presence of a phase by both contact and non-contact methods, check the integrity of wires and fuses.

Types of indicator screwdrivers

Voltage indicators, made in the form of an ordinary screwdriver, have a general principle of operation, but may differ in the form of execution, functionality and device.

There are contact and non-contact.

The indicator in various models can be both a sound signal, a small LED, and even a digital screen.

Impact tools of this brand can be used not only by private users, but also by all professionals who need an effective screwdriver every day. As an example, the most common model of this brand is FORCE 5064. a tool that is of excellent high quality and is able to endure the highest loads. These include the operation of a screwdriver in heavy industrial plants, service stations. The shelf life of this tool is quite long, and during the operation itself, the screwdriver will show itself in the best possible way.

Nevertheless, the result will be more than unpredictable, since these tools will cope with the dismantling and installation of all threaded connections, and there are practically no analogues in terms of productivity. The set includes hardened impact bits, which are made of chrome vanadium steel. For a long time, these tools will cope with all the necessary fixing faults. The kit can include 2 bits with a diameter of 75 mm, and 4 bits with a diameter of 36 mm.

Another good acquisition is the TOPEX tool, which is produced in Poland. If a motorist needs a screwdriver for home purposes and private use, then this particular device will be an excellent investment in the synthesis of quality and price. The cost price is quite cheap in comparison with other impact screwdrivers. This is due to the fact that this screwdriver is not suitable for heavy and constant work in enterprises, etc.

The set of percussion instruments of this brand will include 6 screwdrivers, which are made of high-strength quality steel CrV.

  • What is an impact screwdriver and how does it work?
  • 1. The principle of the impact screwdriver.
  • 2. Comparative characteristics of impact screwdrivers.
  • 3. Features of the work.

Quite often, a household needs to use some tools to fix or repair a particular appliance. One such tool is an impact screwdriver. Every housekeeper should be aware of how this device works to avoid further confusion. This device is intended for unscrewing rusted bolts or self-tapping screws. An ordinary screwdriver will not work for this action. This is directly related to the fact that an attempt to unscrew this kind of bolt or self-tapping screw of an ordinary screwdriver can be perpetuated by knocking down the sting.

An impact screwdriver has certain differences from a regular screwdriver. So, this tool has a reinforced metal case, which, in terms of its technical parameters and dimensions, exceeds the traditional screwdriver case. Impact screwdriver kits often come with two or four bits, which appear to be a cross-head and flat-head. The bits must be installed in accordance with the principle by which they are installed in an ordinary screwdriver. The impact screwdriver tool has a torsion switch, in official terminology, the name of which is “reverse”.

How the impact screwdriver works.

Before you start using the percussion tool for its intended purpose, you must prematurely install the reverse on it, after which the bit itself can be combined with the stuck rusty fasteners and start hitting with a hammer. This must be done up to the moment when the bolt moves out of its mounting dead center.

Difference between Drill Drivers & Impact Drivers

If, when carrying out this procedure, there is a screwdriver in the master’s arsenal, then he will be able to fully replace the impact screwdriver. It is important to note that the rotary impact tool can not only unscrew the fastener, but also install it in a new place. However, after using this kind of screwdriver for unscrewing, it will be possible to remove the fasteners only with it, since other tools will not work.

Features of the work.

In order for the unscrewing procedure to be as simple as possible, you need to wipe the rusted fasteners in advance with a rag, which should be pre-moistened with brake fluid. After that, the impact screwdriver tool must be installed on the head of the hardware. It will be ideal if you install the screwdriver perpendicularly. After that, you need to hit with a hammer on the end of the tool. The success of the work performed will directly depend on how firmly the motorist holds the tool in his hand. In order to exclude any possibility of sliding your palm along the handle of the screwdriver, you should wear a glove, which will also protect your hand to a certain extent from possible damage.

Due to how the fastener rotates slightly around its axis, you should hit it with a hammer several more times, after which the tool needs to be switched to the twisting mode, applying a few more necessary blows. This is what will allow the motorist to achieve maximum results and remove rust from the threads, after which further work on unscrewing will be done with particular ease. After all that has been done, the fasteners will have to be shifted from their previous place and their removal will be possible with a regular screwdriver.

Sometimes it happens that even after all the above procedures have been completed, the hardware will not be affected and the fasteners will not be removed. Therefore, it must again be treated with brake fluid and left in this state for several tens of minutes. This kind of “bath” will facilitate faster dismantling. If, after that, the removal of the fasteners is impossible, then you need to resort to categorical measures. break the fasteners. In order for such work to be comfortable and effective, you need to choose a hammer that is suitable for an impact screwdriver. In addition, you will need the same impact screwdriver, rags and brake fluid.

Professionals can make a screwdriver with their own hands, since for this you only need a rotor from an electric motor, or rather its sleeve and shaft. After that, a piece of steel pipe is put on the sleeve, which will act as a handle. The opposite end must be reinforced with a nut that will prevent the handle from breaking under tension. After that, all the details need to be well welded.

The impact screwdriver works more than efficiently. That is why, in order to remove fasteners from the old place, you will not need to use additional devices. When choosing an impact screwdriver, you need to pay attention to the manufacturer and to the cost price, which should definitely not be very cheap. It is preferable to purchase an expensive tool in cases where the work will be constant and in severe operating conditions.
