How to unscrew and tighten nuts without a key? Unscrew and tighten the nuts

It is possible to tighten or unscrew the large nut on the mixer even if the thread on it has already been torn off as a result of unsuccessful dismantling attempts. You can solve this problem in several ways:

  • The head of the hardware is clamped in carpentry pressures or a clamp and with their help, performing rotational movements, the problem hardware is unscrewed. The same tools can be used to tighten the hardware if necessary.
  • The floor of a horizontally located hardware is put on with an effort a nut with a large diameter, and then this structure is unscrewed with a tool that fits the size of the upper Fastener.

In the case when it is required to Unscrew a round-shaped hardware or hardware, in which all the edges are completely smoothed, you can apply the following methods:

  • Put another hex nut of the appropriate diameter over the round hardware. Next, you need to tighten the nut with pressures or a clamp and Unscrew the hardware.
  • Place another larger auxiliary nut over the round screw nut. At the junction of the nuts, drill a hole into which to insert a stud or drill. Next, the nut must be unscrewed with a Stud.
  • A metal pin is welded to one side of the hex fastener, then another pin is welded to the pin. so that an L-shaped lever is obtained. Using the resulting lever, unscrew the hardware.

In some cases, you can unscrew the problem hardware by destroying it:

  • With the help of a chisel and a hammer, you can swing the problem hardware. The chisel is placed on the edge of the nut and a hammer is struck on the chisel. So alternately pass all the edges several times.
  • If you drill several holes in the hardware, then using a chisel with a hammer you can destroy its structure.
  • Fastener Cut with an angle grinder using a cutting disc or sawn off with a hacksaw blade for metal.

Sometimes it is necessary to Unscrew the tightly wrapped plastic nut. In this case, the following manipulations will help:

  • With the help of a steel tape, which is tightly wrapped around the head of the nut, a rotational movement is performed, using the ends of the tape as a handle.
  • 2 wooden planks are pressed to the edges of the hardware, put them opposite each other. Grasping the ends of the planks with your hands, rotate counterclockwise.
  • To unscrew / twist, you can use an adjustable gas wrench or pliers jaws, spread apart in different directions.
How To Unscrew An Angle Grinder Without A Key

You can twist the hardware with a simple device:

  • Take a long auxiliary bolt and screw a nut onto it;
  • Following it, another one is screwed in, but a gap is left between the nuts, the head of the second screwed bolt or nut is placed in the yak;
  • Both hardware are tightened on the auxiliary bolt so that they firmly clamp the head of the mount to be mounted;
  • Then rotate in the direction of twisting.

When the procedure is completed, the fasteners on the auxiliary bolt are unscrewed and the device is removed. This method is also suitable for the process of loosening the nuts.

What is needed?

To unscrew the hardware, you can choose a hand tool from those that are available. The following items are suitable for this purpose.

  • A standard short open-end wrench and a few coins, for placing them between the horn and the side of the hardware. When creating such a metal gasket, you can use a large wrench to Unscrew a nut of a much smaller diameter.
  • Box spanner with extended handle. Such a tool will help to Unscrew even stuck or rusty nuts, since the large lever allows you to Apply significant effort when unscrewing.
  • A collar with internal teeth, but during operation the teeth can be wrinkled, so with such a tool you can unscrew / tighten only the hardware is not very tightened.
  • Pneumatic impact wrench, which replaces hand tools.
  • Clamp for carpentry, with which you can fix on the Nut and perform unscrewing or twisting.

Recommendations

Before you unscrew the problem hardware, you need to assess its condition and see what tools are available to complete this task. Manipulations should be performed with considerable effort, but at the same time it is necessary.Make sure not to tear off the edges of the nut or break the improvised device.

How easy it is to unscrew the nut of the angle grinder if the disc is jammed

Various mechanisms make our work easier, both in production and in domestic conditions. But sometimes they bring unexpected and NOT too pleasant “surprises”. After all, it is impossible to foresee all situations in which you will have to use the tools.

This also applies to an angle grinder (an angle grinder. an angle grinder), when the cutting disc is clamped on it so strongly that it is not possible to unscrew the clamping nut with a standard wrench or other tools or methods. In this case, there is a risk of breakage of the quick clamping button of the disk and even the tool body, which is usually made of aluminum alloy. The matter is further complicated by the fact that the surface against which the working disk is pressed is often round and it is impossible to stop it.

How to Unscrew a Nut in an Angle Grinder. Which way to turn the nut on an angle grinder to remove the disc?

To reduce the likelihood of clamping the working disc on the angle grinder, smoothly load the tool in order to exclude the disc braking when it comes into contact with the material being processed.

The disc should be installed on the spindle with the pattern (marking) outward (towards the clamping nut), since it is on this side that the disc has a wide metal washer. If the disc is jammed or broken, the movable clamp will be easier to handle as it will slide over the metal washer rather than the rough surface of the disc.

Helps by placing a washer made of cardboard or other not too hard material under the nut. But this method is NOT stipulated by the tool manufacturer, since this may upset the balancing and the reliability of the disk mounting on the spindle is NOT guaranteed.

Heat the retainer nut using a blowtorch or gas torch. The heat source in this case does not matter. The main thing is not to overdo it with heating, so as not to damage the spindle bearing.

We remove the cutting disc in a non-standard way

angle grinder. the most dangerous power tool

Discs on an angle grinder are fixed with a nut, which is screwed in the same direction in which the spindle of the power tool rotates. And when the rotation stops abruptly, self-tightening of the fixing nut occurs.

In order to unscrew it later, you need an effort that significantly exceeds that that arose with a wedge, and it is simply impossible to do this with a “native” or gas wrench.

There is NOT enough strength to unscrew the nut, and the key will come off

You need to do otherwise, namely, remove the cutting disc from under the nut, and then unscrewing the last nothing will interfere.

How to fix disc clamp on an angle grinder

To implement this method, you will need some kind of massive wooden material: a piece of thick board, a piece of timber or just a stump.

Then we take an angle grinder with a tightly clamped disc, turn on the tool and press the fixing nut against the surface of the stump with sufficient force so that it continuously rubbed against the wooden surface.

The process must be continued for two to three minutes. This time is quite enough for the clamping nut not only to heat up, but to glow hot. If heating is NOT stopped in time, there is a risk of damage to the spindle bearing due to overheating.

The degree of sufficiency of the thermal effect on the fixing nut can be checked using a pipette filled with water: drops from it instantly evaporate, as soon as they reach its surface.

Next We proceed in the standard way. Press the button for quick disk replacement and use a standard wrench to unscrew the nut without any effort. In this case, the well-known property of metal helps us to expand when heated.

Reasons for biting

As a rule, this problem occurs on an angle grinder with a working surface diameter in the range of 150-180 mm. When a strong torque occurs, the disc bites. This leads to the fact that the attachment cannot be removed with a conventional wrench, even with the application of serious physical effort.

The second common reason is the use of an angle grinder disc that does NOT match the factory parameters of the tool. This leads to a disruption in the operation of the entire mechanism and jamming. In rare cases, the nut DOES NOT lend itself to loosening when rust appears on its threads. This most often occurs during prolonged use of the instrument or storage without changing the tip.

How to unscrew if it is tightened?

Remember! You need to unscrew in the direction of rotation of the disk. THOSE. If the disc rotates clockwise, then you need to unscrew the nut clockwise.

The easiest way to unscrew the disc mount is to place the wrench and then hit it with a hammer several times with medium force.

If that doesn’t work, there are alternative methods for solving the problem:

  • Heat the fastening mechanism with a torch, which will lead to the expansion of the metal. As a result, the structure will become mobile;
  • Using a small metal plate, grind the disc to the nut itself. Continue grinding until its surface does NOT come into contact with the nut and does NOT start twisting it;
  • Insert a steel pipe into the holes in the nut, use it as a lever to unscrew the tightened nut. Do not use too much force so as not to break the thread;
  • Lubricate the threads with a machine oil such as WD-40. Wait 3-5 minutes and then try unscrewing the mount with a wrench. Using this method, you can get rid of rust inside the landing shaft;
  • If you need to remove a circle that has not been used for a long time, you can start tightening the fasteners even more. After that, trying again will weaken him;
  • Boiled or rusted threads on an angle grinder can be treated with turpentine, vinegar, white spirit or rust remover. After processing, you need to wait at least 30 minutes, and then try again Unscrew the nut.

If a situation arises when you are left without a key, you can cut down the stuck mount with a chisel or grind it off with a second angle grinder with a disc for working on metal. After that, you will have to restore the thread, as well as look for a spare nut. If the circle still DOES NOT lend itself, you can try combining different methods. For example, treat the shaft with machine oil, and then start unscrewing the nozzle with a lever or knock the mechanism with a hammer.

What are the ways to unscrew the tightened nut on the angle grinder?

angle grinder, or angle grinder. a versatile tool with which you can perform a wide range of actions. It has a simple mechanism of action, built on the rotation of the shaft by an electric motor. Essential for cutting metal parts, polishing surfaces and sanding various materials. One of the common problems during operation of an angle grinder is biting the nut that holds the disc. This does not allow replacing the nozzle, and with strong impact, you can damage its thread, break the key or break the body.

How to avoid snacking?

To avoid trouble when changing the angle grinder attachment, it is advisable to prepare in advance for work. To do this, you can insert a small spacer between the disc and the nut. Suitable material is cardboard, a piece of linoleum or plastic.

If the fastener is constantly tightening too tightly, it is advisable to use a circle with a smaller diameter. It is also important to keep the tool clean, timely Treat the thread with oil, WD-40.

The angle grinder is a simple and useful tool for home or professional use. The most common problem while working with it is biting the nut that holds the disc. This can be dealt with by mechanical action on the mechanism (blows to the mount, using a lever and grinding the disc), and by chemical methods. treating the thread with oil or rust solvent.
