Many people in their life faced with the task of urgently unscrewing rusty nuts and bolts. And it often happens that the repair itself is very minor, but the fight with the bolt can easily spoil the whole mood. But there are folk ways with which you can quickly and without nerves solve this problem. Let's find out how to unscrew a rusty bolt at home without special tools and tools.
Use leverage
This is the very first thing that comes to mind if you need to unscrew a rusty or soured fastener. As a lever, you can use an ordinary pipe, which is put on the key. Previously, it is better to walk along the bolt itself and around it with a metal brush. To work with a lever, it is better to choose a box wrench, but an open-end wrench will do. You should work carefully. key caneasy to break and hit on the fingers. It is not necessary to apply excessive efforts when unscrewing - one or two powerful short-term jerks are enough. Here the main task is to break the bolt, that is, to destroy the oxides that have formed over a long time in the "bolt - nut" pair. In addition, if you apply excessive force, you can easily lick off the edges of the head, break the key or the bolt itself. And then you definitely cannot do without special heads for torn edges.
Chisel
Here is another effective way to unscrew a rusty bolt at home. But do not think that a hated nut or bolt can be cut down with a chisel. With this tool, you can actually pry the fastener out of the rust holding it. It is necessary to sharply hit the chisel with a hammer. In this case, it is installed to the edge of the bolt at a slight angle. The tool is directed at an angle in the direction opposite to the thread. Then they make a strong and sharp blow with a hammer.
Thus, experienced locksmiths can break even the most complex bolt or nut in a few seconds. Of course, to use this method masterfully, you will need some experience, but this method definitely works.
Tapping
Oxides and rust are formed inside the thread during the operation of the connection. The bolt or nut is literally attached to the thread. If these oxides are destroyed, even that which should not be unscrewed will be unscrewed.
You will need a spacer for the size of the bolt head or nut. A hammer will also come in handy. With thesesimple tools, the bolt head is tapped from all sides if possible. You can also hit the head several times. If the oxide deposits are not age-old, then this will be enough and the bolt can be unscrewed.
Looseness
Before using any methods to unscrew difficult fasteners, craftsmen traditionally try to unscrew the connection using wrenches and socket heads. It is possible that when you try to loosen the nut or bolt has already moved a little along the thread, but so slightly that it is not noticeable to the eye.
You can try to loosen the connection. To do this, with a key or socket head, on the contrary, they try to tighten the bolt even more, but within reason. Next, try to loosen the bolt. You can hear a characteristic crunch. This means that the oxides have collapsed and you can carefully, slowly, unscrew the bolt or nut.
Warming up
Here's another way to unscrew a rusty bolt at home. Its only drawback is that it does not always fit. For example, they can not be used everywhere in the car. But the effectiveness of the method is much higher than the previous ones.
The bottom line is to heat up the soured bolt. When heated, the metal expands - this is a school physics course. This means that when expanding, the oxides will collapse and the bolt will come out as if the connection is new. For warming up, you can use everything that is at hand: portable gas cylinders, soldering irons, a gas cutter, batteries and a graphite rod. Thisthe method differs from all the others in that it is effective for tasks such as unscrewing a rusty bolt in a hard-to-reach place. Where it is not possible to knock, where it is not possible to moisten fasteners with chemistry, the flame of a mini-torch will easily get there.
A bolt or nut should be heated to a sufficiently high temperature - even red-hot. Then some locksmiths prefer to cool the heated part with water, while others do not wait until it cools down. In any case, after heating, you can try to unscrew a difficult bolt with a ring wrench or socket head. From the first time, the fasteners may not succumb, but from the second or third it will definitely work. You can use this method in combination with those already described above. But not a single connection has withstood the heat yet: everything spins up, the main thing is to heat it hotter.
WD-40
Let's move on to chemical methods, how to unscrew a rusty bolt at home. The first thing that comes to mind is that same VD-40 liquid. And let them say that the liquid is expensive, so far they have not been able to come up with a better one. Manufacturers keep the composition secret, but it is known that about half of the "VD-40" is kerosene. He is able to penetrate into any cracks. By the way, instead of "VD" you can use analogues (for example, from the company "Mannol").
To combat oxides and fasteners, it is enough to splash a bolt or nut abundantly. But first, access to the thread should be provided. Otherwise, the use of liquid will lead to nothing. Literally after 20 minutes, you can try to unscrew the bolt or nut. The element must crackle and crunchget out.
Solvents
Speaking of chemistry, one cannot but say about folk remedies. You can unscrew a rusty bolt using gasoline, kerosene, turpentine, white spirit. A can of WD-40 is quite expensive, and acquiring it for the sake of one harmful bolt is not always wise. Therefore, solvents can be used. All of them have a very high penetrating power and can easily get inside rusty threads.
So where to start? The place around the fastener is carefully cleaned with a metal brush, then the fastener is abundantly poured with kerosene, gasoline or other chemicals that are at hand. After 15-20 minutes, you can try to turn away.
Vinegar Essence
Experienced locksmiths shared their experience on how to unscrew a rusty bolt at home or in a garage. The liquid that housewives use in the kitchen comes to the rescue. 70% vinegar essence is a real acid, which means it can defeat rust and oxides.
The place is cleaned with a metal brush, then the rags are abundantly moistened with liquid and the fasteners are covered with this rag. After some time (usually 20 minutes is enough, but may be longer), the bolt will loosen. Hard at first, then lighter.
Coca-Cola
This is not a joke at all, but one of the ways to unscrew rusty nuts and bolts. Everyone knows that the composition of the popular drink contains phosphoric acid. It is used for degreasing and to combat corrosion products. Naturally, this timetakes longer than with essence or WD-40, but if there is nothing else, then you can try.
It's very simple. The surface near the fasteners is abundantly filled with a sweet drink, and then all that remains is to wait. After a few hours, you can try to unscrew.
Brake Fluid
And here's how to unscrew a rusty bolt in a car if the car is on the way. Brake fluid will help. It has great penetrating power and can easily get where even kerosene can't. After a few minutes, you can try to unscrew the connection. As practice shows, this is a very effective folk remedy.
