When disassembling old devices or structures, sometimes a situation arises when a bolt has stuck. 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, one or another method may simply be meaningless. When working, be sure to pay special attention to safety precautions to prevent possible injury.
How to pull out a stuck bolt
- Using a gas burner. It is necessary to singe the surface where the bolt has stuck, how to unscrew it in this case, it becomes clear even to a schoolboy. In this case, dirt and rust will turn into ash, and the metal will become much softer and more pliable, making it easy to pull out the stuck bolt.
- Using a drill. You can use the thinnest drills to make several closely spaced 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 can be easily removed. It should be noted that the depth of the holes should be small so as not to damage the bolt shaft.
- Using acid andalkaline mixtures. Rust and dust under the influence of acid between the nut and bolt will dissolve, the distance between them will increase, and with the help of a tool you can easily remove the stuck bolt.
How to unscrew a stuck bolt
In the event that it is necessary to ensure the safety of the bolt and the product, you should try to unscrew it using the following methods:
- Heat the connection with an open fire. 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.
- Tapping the surface of the nut with a hammer. When the bolt is stuck, how to unscrew it using tapping? Pretty simple. It is enough to tap the nut with a hammer with moderate force, and the rust may lag a little behind the junction area of the nut and bolt, which will allow unscrewing while maintaining the integrity of all elements.
- Lubricate the bolt with whatever lubricant is at hand, making sure it slides between the bolt and nut so that it can be removed.
- Using a hammer and chisel. With a chisel, several notches are made on the surface of the nut, with the help of strong blows of the hammer, the nut is scrolled. This method is the most radical, because if you do not calculate the force correctly, you can beat off part of the bolt, and the work will not bring a visible result. However, if you manipulate with care, a 100% result is guaranteed.
Unscrew the stuck bolt is not a problem
As you can see, there are a lot of possibilities when a bolt has stuck, how to unscrew it and not damage it. If you use all the recommendations correctly, then you won’t need much work to solve this unfortunate problem. However, there is no need to be zealous, because excessive pressure, as well as the simultaneous use of all methods at once, can lead to undesirable consequences, from damage to the bolt itself to bodily injury that can be obtained in the process of removing it.
