How to unscrew the screw? #NOCARadd

Trying to repair the car on our own, we have to reckon with the fact that we will meet many obstacles along the way. Some will be more burdensome, others a little less, but we will definitely encounter some. Especially if our car is already several years oldand here and there we see rust. Repair of such a car specialized tools may be required which we don't necessarily have. What can we do to make our repairs effective? What to do with stuck and rusty screws? 

A good key is the key to success!

The claim is obvious, but still many people tries to unscrew bolts or other parts of the car with mismatched keys. This is because we either don't know what to do or we think we can do it without the right tool. And this is often true - a few combinations, devised in the privacy of a garage, and the screw is unscrewed. However, you should be aware that working with bad, unsuitable tools will significantly increase the time and may damage the unscrewed element. To think about DIY car repair, we will acquire a set of necessary tools. However, don't buy the cheapest wrenches because we will most likely destroy the screw heads. We'll invest in a decent setthat we will have for many years. Socket wrenches, handles, ratchets, etc. are available in multiple sizes varying in size. In addition, sockets can have a different profile - suitable only for hexagonal screws or universal. Remember that the smaller the screw, the more accurate the keys need to be.

Rattle for problems

Auto repair requires a lot precision and accuracy. Sometimes we need to get to places that hardly available and inside which we cannot use a hard key without mechanisms. Then help comes ratchet handle... This smart device does not require removing the key from the cap and reinstalling it, which is especially difficult in places with poor access, but it is enough. short handle movements (several or several tens of steps) back and forth, due to which unscrew or tighten the self-tapping screw. Most profitable to buy ratchet complete with heads, packed in a practical box and guarantees compatibility of all components.

If the rattle doesn't work ... take a Coca-Cola

It must be remembered that the rattle, despite its undeniable advantages, not suitable for loosening stuck and rusted screws. He does not like too much resistance, therefore, if you try to unscrew something by force, you can damage the tool. To use the rattle, we must first loosen the bolt with a hard, strong wrench, then use the ratchet for further action. If we have a problem with a stuck rusty screw we can try loosen coca colaą... Will work when our baked goods are not yet extreme. However, if that doesn't work, then there will be the bolt rusted well, most likely on the outside. In such cases, a simple drink is not enough.

Mechanic vs amateur

View work car mechanic, we probably won't notice Coca-Cola in their workshops. They prefer a slightly different way of dealing with rusty and tightening screws. Let's take a look at their methods:

1. The first is thermal method - heating the element into which the screw is screwed, so that it expands under the influence of temperature, which makes it easy to unscrew the connection. In the case of nuts, the case looks a little less colorful - it is best to heat the nut itself, which, due to its size, can be difficult. Sometimes, however, it is sufficient to treat the entire component with hot air to detach individual elements. As an amateur, you probably don't have the whole arsenal of workshop tools at hand, so you are wondering what to heat. Well, all you need is a small heat gun or a miniature burner, things that can be useful in a variety of situations, so it's worth equipping your workshop with them.
2. second method use of a penetrating agent Sometimes it is enough to spray the baked area with a suitable preparation, which is designed to penetrate the rusted areas and penetrate between the baking zones, so that it will ensure the movement of difficult-to-pass joints. When purchasing this type of product, choose a reputable manufacturer, for example Liqui Moly, then we will be sure that this product will actually work.
3. The third method is use of a multifunctional drug - It's not as effective as its penetrating counterpart, but it's good to have one in your garage. After applying to the screw, you will have to wait a bit until the drug "bites". This may take from several to several tens of minutes. This will be most effective on screws that are not very tight and closed.
4. The fourth way is do not loosen corroded screws too muchhow much to protect them to prevent corrosion. For this it is used assembly pastes, especially copper. They prevent the screws from jamming as they are heat resistant. Also useful for security multifunctional drug, which also has anti-corrosion properties - when buying a product, pay attention to its quality, the better the product you buy, the more versatile and valuable its action will be. Well-known company Liqui Moly, she created multifunctional aerosol which not only has protective and anti-corrosion properties, but also displaces water from electrical systems and makes it easier to start the engine.

Sometimes an idea is enough

The most common problem with screws occurs during loosening the wheels. And it is in this case that the solution is quite simple - due to the fact that we have a lot of space, we can use long tools, which facilitate unscrewing.In order to properly unscrew the bolt from the wheel, it is enough to take a long wrench. If we still cannot, we can apply extension wrenchmade, for example, from a long pipe. Of course there is always risk break the bolt, so do not forget to lubricate the bolts so that when changing wheels you can successfully unscrew even those that have not been touched for a long time.
