Every person in his life more than once faced such a nuisance as rusted and stuck fasteners. This situation is known to everyone: motorcyclists, motorists, cyclists, locksmiths and plumbers. Last in particular.
It often happens that it’s just necessary to replace the wheel or change the tap in the apartment or house, and the nasty nut or bolt does not want to get out. Power methods will not help in this situation: the nut sits dead. And it’s not always possible to apply excessive force to it. You can easily break something, break the thread, cut off the edges of the elements. In order not to spoil the nerves, and in this situation this can not be avoided, you need to know how to unscrew the rusted nut at home. There are several effective ways to do this.
Why and what to do?
Repair can be seriously difficult, the replacement of necessary parts will have to be postponed until later. Corrosion is to blame. And the reason for this is very, very commonplace. For example, during installation work at the factory or in the course of previous repair work, "professionals" in a particular area decided to ignore the processing of fasteners with lubricant. Then liquid got under the thread. Water caused loosening processes on the surface of the bolt and nut. This loosening tightly linked the parts with a new compound at the molecular level. How to unscrew a rusted nut is a science, and the unscrewing process can take a lot of time, effort and nerves.
Use of assistive devices
The first thing you must definitely try is various means, among the properties and characteristics of which are indicated the reduction of friction and the dissolution of various contaminants. This substance can be absolutely any tool that has a high penetrating ability. The modern market offers a wide variety of products that can facilitate the process of loosening a rusted nut.
The most popular drug for these purposes is the legendary composition WD-40. This is really a unique tool that allows you to solve not only this, but also many other problems. Before unscrewing the rusted nut, carefully spray the bolted connection with liquid from the can and wait a little.
But the WD-40 is not the only option. The preparation contains kerosene, which means that if the master also has kerosene, gasoline, diesel fuel, then this is not an optimal choice, but it’s still effective. In any case, it will be possible to unscrew the nut.
Another available improvised remedy is acetic acid. If any other mild acid is freely available, then you can use it. Here are the same recommendations - thoroughly moisten the compound.
At the very least, American technology will help. At the nearest supermarket you can buy 0.5 liters, or better a whole liter of Coca-Cola. The composition of this miracle drink has phosphoric acid, which, albeit imperfect, but will help to solve this problem.
Before unscrewing the rusted nut, the connection is thoroughly wetted with any of these means. Then you can relax for about 20 minutes. This will be enough for the drug to show its penetrating abilities. While the liquid will penetrate, you should knock on the culprit with a hammer. Knocking is necessary around the perimeter. The element should be torn off gradually, swinging the nut. If it doesn’t work out, it’s worth dousing the compound with any of the preparations and waiting even longer. If it again fails, then it is worth looking for another, more effective way, how to unscrew the rusted nut on the mixer or somewhere else.
Solving the problem by heating
If the nut stubbornly does not want to give in, then it is worth applying heat. It will not be a secret to anyone that any metal, if it is heated to certain temperatures, has the properties of expanding. Therefore, it is definitely worth trying as one of the options to warm the nut well. Then, before it cools down, you need to try to rip it off. But everything should be done as quickly as possible, otherwise the bolt will also heat up, and then things will not be. But even if the connection is fully warmed up, this process will occur unevenly. The rust warps and loosens the nut.
In order to sufficiently heat the fastener, you can use any available features. It can be a lighter, matches, boiling water. Building hair dryers, powerful soldering irons, blowtorches are best suited . Before unscrewing a rusted nut, make sure that your hands are properly protected. You should work carefully and extremely carefully. If there are wooden parts in the working area, the nut must not be heated: this can lead to wood damage.
Spin
In addition to these two proposed methods, he also recommends not twisting, but twisting the part. Often this way it turns out to move the rust layer and swing the fastener, after which it can be easily unscrewed. This option can be combined with heating.
Tapping
In the process of tapping the faces, everything is unscrewed, even if the nut is very rusted. How to unscrew? Just tap on the perimeter of the fastener. In the process of shock microdeformations will occur. These deformations will destroy the rust layer. But here it is important not to make serious efforts. Shocks should not be strong, according to the size of the connection. If you hit hard, you can damage the edges, and then the nut will never loosen.
Destruction and destruction
If no method is closer to solving the problem, it remains only to destroy and destroy the connection. There are also several options. The method is selected based on where the nut is rusted. How to unscrew? Yes, just saw it with a grinder or just a hacksaw with a metal blade. But not everywhere, you can destroy the connection by cutting. For example, in a car wheel, this will not be easy. On the faucet in the bathroom, the faucet itself can be damaged.
If there are already no options how to unscrew a rusted nut, for example on a wheel, then you can try to drill the wrecker with an electric drill. Another effective way - using a thin chisel and a hammer, you can make grooves on the edges of the product. It is necessary to deform the part very evenly on each side so that it can be easily unscrewed. Naturally, instead of this, you will then have to screw a new one.
Prevention
It is much easier to take care of bot information, so that later you do not have to think about how to unscrew a rusted nut in a home or garage environment. It is worth following the recommendations, tighten the part to a certain point, always lubricate the connections.
