When disassembling old appliances or structures, a situation sometimes arises when a bolt has become attached. How to unscrew, there are many effective methods. But it should be borne in mind that depending on the situation, as well as the material of the product, from which, in fact, it is necessary to remove the bolt, this or that method can be simply meaningless. When working, it is imperative to pay special attention to safety measures to prevent possible injuries.
How to remove a stuck bolt
- Using a gas burner. It is necessary to scorch the surface where the bolt stuck, how to unscrew it in this case, it becomes clear even to the student. At the same time, dirt and rust will turn into ashes, and the metal will become much softer and more pliable, so you can easily pull out the attached bolt.
- The use of a drill. Using the thinnest drills, you can make several nearby holes and insert a chisel there. A few hammer blows on the chisel will cause a complete split of the nut body itself, in which case the bolt is easily removed. Keep in mind that the depth of the holes should be small so as not to damage the bolt shaft.
- The use of acid and alkaline mixtures. Under the influence of acid, rust and dust will dissolve between the nut and the bolt, the distance between them will increase, and with the help of the tool you can easily remove the stuck bolt.
How to unscrew an attached bolt
In the case when it is necessary to ensure the safety of the bolt and the product, you should try to unscrew it using the following methods:
- Warm connection with open flame. In this case, when heated, the metal will gradually heat up and, accordingly, expand, which will allow you to unscrew the bolt by removing the nut.
- Hammering the surface of the nut. When the bolt is stuck, how to unscrew using tapping? Pretty simple. It is enough to tap the nut with moderate force with a hammer, and the rust may slightly lag behind the area of the nut and bolt connection, which will allow for twisting, while maintaining the integrity of all elements.
- Lubricate the bolt with any grease at hand, ensuring sliding between the bolt and the nut so that it can be removed.
- Using a hammer and chisel. A chisel makes several serifs on the surface of the nut, with the help of strong blows of the hammer, the nut scrolls. This method is the most radical, because if you do not correctly calculate the force, you can beat off part of the bolt, and the work will not bring visible results. However, if you perform the manipulation with caution, a 100 percent result is guaranteed.
Unscrew the attached bolt is not a problem
As you can see, the possibilities, when the bolt stuck, how to unscrew and not damage it at the same time, a lot. If all recommendations are correctly used, then special work will not be required to solve this unfortunate problem. However, one does not have to be zealous, because excessive onslaught, as well as the simultaneous use of all methods at once, can lead to undesirable consequences, ranging from damage to the bolt and ending with bodily injuries that can be obtained in the process of removing it.
