Angle grinder does not unscrew what to do

Why bites the nut on the angle grinder that holds the disc

I will say, perhaps, a well-known truth. It bites nuts more often on angle grinders with a disc size of a significant size, say 150-180 mm or more. The thing is that the resulting torque, in the case of a disk impact at the time of the start of cutting, is much greater than for a disk, say 125 mm. As a result, the nut is tightened by inertia so much that it is very difficult to break it in the usual and usual ways. Now about the special ways.

How to unscrew the disc nut of an angle grinder (angle grinder) if it is bitten

So, if there is no way with the key, even if you insert it and hit it slightly with a hammer, then we begin to use something more serious.

The first thing you can try, but again without fanaticism, is to take a rod, insert it into the holes on the nut and, using a hammer, move the nut in the direction of its untwisting. The main thing here is not to break the button and not to rip the holes, as here

angle, grinder, does, unscrew

The second thing that many advise is to warm up the nut. We warm up the nut. As a result, it is slightly, but physically still obliged to expand. Resizing may or may not help.

Do not pull all the way until the scroll hold button stopper or the button itself bursts. In this case, it is not the tool with which you unscrew it that breaks, but often the case of the angle grinder.

How To Free Up An Angle Grinder Disc That’s REALLY Stuck

The third method is the most effective, and, oddly enough, one of the safest for the angle grinder itself.
We take and break off the edges of the disk along the nut.

Next, we use a thin metal plate or another disc (thinner), and maybe a second angle grinder with a disc. In this case, a broken disc must be turned either with a plate or a disc. We try to sharpen the disc so as not to damage the nuts holding this disc, because they will still be useful to us. So we sharpen the whole broken circle until we grind it off and the nut is unscrewed.

This business is 4-5 minutes, no more.

How to unscrew a disc (nut) on an angle grinder, if bitten, jammed, cannot be unscrewed

an angle grinder, or as it is called more popularly and in a popular way, an angle grinder, nowadays an indispensable and very useful tool. Without him, neither here nor there! And if it suddenly fails, then you have to dodge in every possible way, look for alternatives and think about restoring the instrument. At the same time, it is impossible to use an angle grinder for its intended purpose because of a kind of simple lining when the disc does not unscrew. Rather, the nut that holds this disc is not unscrewed. Here you can “break the wood”, namely, bend or break the key, damage the lock button, break the case, but never unscrew that same unfortunate nut. So, we will warn you right away, if it is not too late. If you suddenly do not unscrew the nut holding the disc with a key, then you need to change tactics. And it is precisely the cardinal method of unscrewing that our article will be devoted.

How to avoid biting the disc nut on an angle grinder

And a few words about preventing such unpleasant precedents again. You can use small cardboard spacers by inserting them between the disc and the nut. As a last resort, we use a disc of a smaller diameter, unless, of course, the nut is tightened from above. As a result, it will be possible to unscrew such a nut without any problems. It will not be squeezed, for a bite on the carving.

Angle Grinders. 5 Common Issues & How to Fix Them

Burner use

The law of physics is guaranteed to work, and the body (read: hub nut) will expand. And this will greatly facilitate the removal of the stubborn part. There is one “but”: not only this one part is heated, but everything else, in the area of ​​the burner. For example, a bearing. And this is better not to be allowed. As a more gentle option, we can suggest using a soldering iron and. patience. You will need it.

Strong hammer blows

You hit the hub. you hit the bearing! If you carry out a replacement, then go ahead! If you value the bearing, avoid this method.

Warming up the hub nut with a burner. Not recommended!

Jumping on the lever

A chisel will help to break the hub nut

The “method” is fraught with the danger of unexpected breakage of the nut edges, breakage of the key, and so on. Just don’t do it like that.

Remove the nut from the car: power method

  • Lever from the pipe (length not less than one and a half meters).
  • Powerful socket wrench (450 mm.).
  • Corresponding head.

We put the head of the key on the nut of the hub, insert the knob and push the pipe onto the handle. Gradually increasing the applied forces, we turn the part away.

As experienced car enthusiasts say, few hub nuts can resist for a long time if you use a “Zilovsky” balloon!

How to Unscrew a Hub Nut. The Gentle Way

  • Tubular socket wrench. “knob”. The tool must be made of high strength steel.
  • Powerful screwdriver.
  • Iron pipe.
  • WD-40.
  • Metal brush.
  • We clean the thread from dirt using a brush with metal bristles. The hub nut should now be impregnated with penetrating grease. For example, WD-40.
  • We saturate the hub with a penetrating mixture. You can rest for 10-15 minutes, and then you should put the head of the key on the nut and hit it with a hammer several times, gradually increasing the force of the blow. Just do not overdo it: the point of this action is to make a slight deformation of the nut, due to this it will be easier to remove it. And immediately after the blows, you should try to unscrew the hub nut on a VAZ or a car of another brand.

The hub nut does not unscrew what to do

Which way the hub nut is unscrewed

Yes, it may very well be that you are one of the lucky ones who will not need extra effort, since the problem with unscrewing the hub nut may simply be in the wrong direction.

So, we take the crank and, when your car is far from new, try, if the nut does not lock, on the left wheel. unscrew the nut counterclockwise, and on the right, clockwise. In modern brands, usually both left and right, you need to unscrew the hub counterclockwise.

Before you start unscrewing the hub nut, do not forget that it breaks off when the machine is on its wheels, and there are stops under them. On the side from which the nut will be unscrewed, the stop is securely installed.

Although if the nut is located deep, and the brake disc is ventilated, then you can try to unscrew (fixing with a powerful screwdriver) and so, only making sure that the car is reliably insured. Remember also about personal safety: protect your eyes, do not be too zealous, because you can accidentally injure yourself or spoil the body of the car in the courage and enthusiasm.

Unfortunately, in most cases, it is not enough to use a wrench with a large lever, you have to use additional tools, special mixtures. Consider the rest of the options.

Easiest way to unscrew / rip off the hub nut

The following can be considered the easiest way, but it involves a complete replacement of the nut. Don’t worry, any method does not guarantee that this part will be preserved. To easily unscrew or rip off the hub nut from its place (an option for all brands. from VAZ to foreign cars, where there is a groove on the shaft), you need to take:

Unscrewing the VAZ hub nut with a drill

  • New nut.
  • Drill or screwdriver.
  • Drill up to 3 mm.
  • Chisel.
  • Hammer.
  • It is necessary to drill the nut along the groove for de-locking.
  • With the help of a chisel and a hammer, we simply break the nut and remove it, followed by replacement.
  • If it is not possible to throw away the nut, then you have to sweat. and in the literal sense of the word too.

How to unscrew a stuck bolt or nut?

Among detachable connections, threaded takes the first place both in prevalence and reliability. However, in practice, there are many cases when it is not easy to unscrew a threaded pair.

Mechanical methods.

These include methods that make it possible to disassemble a threaded connection through the application of mechanical forces:

  • the use of box wrenches and socket heads instead of open-end wrenches;
  • using a lever to increase effort;
  • impact with a variable direction of force;
  • accentuated impact (short-term application of significant effort or effort at certain points);
  • impact destruction of oxide and rust layers.

The open-end wrench covers only three facets of the nut or bolt head. In addition, there is some gap between it and the edges. In this case, applying enough force to unscrew can be a problem. the key can break off and “lick” the edges. A spanner or socket wrench covers all edges, allowing more force to be applied.

To increase the effort, you can use the lever. increase the length of the handle. In this case, there remains the danger of licking the edges or destroying the fastening parts. You can also damage those parts that were connected by a threaded pair.

Often, a change in direction helps to unscrew a stuck or rusted nut. before unscrewing the connection, they try to screw it. The action of forces alternately in different directions destroys the layers of rust, giving movement to the parts of the connection.

An example of the application of a short-term significant force is given by the method using a chisel and a hammer. A notch is made on the edge, a chisel is pressed into it (guiding it in the direction of unscrewing the nut) and hitting it with a hammer. In this case, the impact force is much greater than that which can be applied using a wrench. Since the impact is short-term, it cannot destroy the bolt.

For your information! In this way, you can also unscrew the nut with the torn off edges. This is somewhat easier than trying to file new ones for a smaller key size.

Lightly tapping the nut and / or bolt with a hammer will shake the entire structure and destroy the rust layer. It is only necessary to dose the force of the impact, so as not to damage the parts, not to deform the thread. Although as one of the methods for disassembling a “recalcitrant” connection, destruction by such blows of the nut is suitable. The only problem is that the threaded pair will have to be changed.

Rusty nut

Another problem that is familiar to motorists (and not only) is a rusty nut and / or thread. In this case, you should not make a heroic effort to unscrew the fasteners. Your edges will simply “merge” and another problem will be added to the boiling thread. If, after a couple of attempts, you can’t unscrew, try the following methods one by one:

  • Use a wrench to tap the bolt. There is a chance that the rust will crack and the nut will be unscrewed.
  • Fill the compound with kerosene and wait. It will corrode the rust, after which it will be easier to unscrew the rusted nut. But during this operation, you cannot smoke, turn on welding, be near an open flame.

Strippers for stripped nuts

You can also fight rust with a lubricant. Try filling the joint with a flowing multi-purpose grease (available in cans of WD40). After waiting a couple of hours, we try to work with a key. Didn’t work. try alternately other methods.

Find out what to do if the bolt is stuck. How to unscrew?

If you have opened this article, it means that strong words are behind, you pulled yourself together and decided to find answers to the questions: “What to do if the bolt is stuck? How to unscrew it? ” Let’s try to figure out this problem.

What to do if you can’t remove the bolt

First of all, you need to split the bolts into bolts with a whole slot and a torn slot. If the spline remains intact (no matter what spline it was), this is half the problem and there are chances that the process will speed up. From here follows the first rule. thoughtless application of force is fraught with a damaged key and a ripped slot / bolt head. Accordingly, it is not necessary to apply full force if there is a suspicion that the key will come off. Often the key jumps off due to the fact that the slot is not completely thrown over. For example, the key-head is not completely put on and then even a small application of force kills the bolt head. It is also important to monitor the size. in no case try to unscrew the bolt with an unsuitable / wrench.

If there is a suspicion that the key is already on the verge and may suddenly turn, then remove the key in advance and think about how else you can grab the bolt. Pliers or a gas wrench with a strong grip can come to the rescue. One way or another, try to preserve the existing head as much as possible. After all, otherwise it will be necessary to weld a new nut directly onto the cap, and this is not the easiest procedure.

How To Remove Stuck NUT Of An Angle Grinder. Very Simple

Unscrew the torn off bolts and nuts

Slicked edges on bolt heads or nuts are not uncommon. Excessive forces applied when tightening, and then when loosening, often lead to the fact that the border between the bolt faces is erased. If the bolt is not unscrewed, ordinary keys are powerless in this case. they simply scroll, and the fasteners remain in place.

Torn or lapped edges on a nut or bolt prevent it from being unscrewed

There are several ways to unscrew shear bolts and nuts:

    With a gas adjustable wrench. Due to the ribbed jaws, adjustable degree of “tightening” and a sufficiently large lever, an adjustable wrench helps in most cases. This tool is not uncommon, so the first thing to do if you need to unscrew fasteners with a lapped thread is to try this method.

A gas (pipe) wrench is the best tool for loosening nuts

How to work with the extractor

If there is a plastic or rubber gasket under the bolt, remove it and try one of the suggested methods again. If you cannot unscrew the bolt with the torn edges by all these methods, one thing remains: cut / saw down the cap and drill out the pin.

Basic methods

Regardless of the method used, the main thing is to be patient, unnecessary haste can only aggravate the problem, which will take much longer to solve. Before choosing how to unscrew the bolt, you need to determine the cause of the problem and make a plan.

Among the most effective methods are:

For work, it is better to use several types of drills of different diameters. You need to drill starting from the smallest, which is necessary for accurate work. It is important to hold the drill vertically so as not to damage the mounting hole. It is recommended to use coolant during operation.
