A carrier-wheel-bolts and nuts fitted with a special head that cannot be fitted with a normal balloon key. To recover a secret bolt, you must use a "return part"-a special head that is sold in a set of secrets and stored in a separate, secret place.  The History of the Declassilating

The History of the Declassilating

A cigarette or secret bolts were invented by Italians even before World War II. Because of the lower standard of living, marginal elements from the southern regions of the country have infiltrated the cities of northern neighbours to commit theft. The cars, first of all, were stolen, but they were not averted by the wheels. To protect against the robbers of the Northerners and come up with "cunning" bolts.  Mass production of "secret" has started there, but only in the post-war period.

In order to make it more difficult for a thief to use some of the declassification, the rotating rings are used by the shell outside. Trying to make these secret pliers are doomed.

We owe the secret bolts in our country to the seventieth years of the last century, the time of the commodity deficit.  The unconventional wheel charmer was almost the only way to protect his property. The wheel theft was a serious problem, as it was not possible to buy them at the store "simply". As a result, the carers imported kits from foreign trips or ordered familiar metal processing specialists working on factory machines. There were no "top secret" straps or teeth on top of the top secret. These were simple wheel-bolts with heads overrated by the cylinder head and removed from the centre of the pins on the head of the head. The special key was made with a hole inside, which allowed him to put on the head and screw the bolt.

Purpose and device of the secret bolts

In our time, in order to prevent the theft of expensive regular or non-regular wheels, auto-amateurs use "secret" as before. The principle remained the same, but the structure of the head has changed. Modern heads and keys are equipped with a complex profile which, without having an original key, is difficult enough.

In the nineties, bolts and nut clips were distributed. It was easy to say, and it was worth a set of classified secret. However, it became clear that the device of this type of thief is able to be turned away with the help of a gas key or a pair of pliers with long handles. The bolts with the internal figure of the puzzle are placed on the inner walls of the hole, thus unlocking them without the use of special keys is problematic.

How to select secrets when buying

When you select the secret bolts, you should at least visually verify that the bolt is not actually available for the flipping switch without a key. It is not recommended to purchase too hard bolts because they can compromise the balancing of the wheel. The length of the secret bolt, which must correspond to the staff (± 1 mm), is not the most recent. If the bolt or nut is too long, you will not be able to draw the wheel to the end. If the bolt is short, it can be turned on or "cut off", leading to an unexpected loss of the wheel.

The reliability of the secret is dependent on several factors

The smaller the length of the protruation of the bolt, the more difficult it is to grasp it with a tool. As a rule, the bolts of the bolts are largely free of bolts, and the probability of replacing the "native" key is small.

The second important factor is the promotion of the elements of the protection of the pazas, the pros and projections. Too small pauses and proteges can play tricks on the master-the key can simply not be inserted if they are caught in mud. This includes the complexity of the figure-the number of points on which the key is placed (one, two, three). The larger the area of the key points, the smaller the chance to accidentally collapse it. A major factor is the steel brand, which defines its stability to the drilling. In addition, the use of a solid alloy makes it possible to make the profile sketch itself more accurately and more original, which makes it difficult to match the key.

The level of uniqueness of the classification depends on the extent to which the manufacturer has released a batch of secret bolts with such a picture. As a rule, the smaller the size of the released batch, the higher the price of "secret". The quality of "secret" packages can also be said in terms of the number of released kits. As a rule, the simplest, price of 150-200 rubles, the world's circulation of more than a hundred thousand sets and the key to them is easy to choose. There are original secret wheel-bolts produced directly by the car manufacturer. Their advantage is that if you lose a key, you can purchase a new unique identifier on the package. The price of such a secret ranges from 3,000 to 5,000 rubles per set.

Operational issues

If you have already installed the security bolts, we recommend that you comply with the following maintenance guidelines:

1. In order to avoid damage, do not use the pneumotool when removed, especially when the "top secret" is mounted. End and unscrew the top secret bolts manually by the ballpoint or the dynamometer (50 N/m recommended).

2. When the wheel is removed, always loosens the "secrets", then the bolts (nuts). When mounting the wheel, first twist the screws (nuts), then "declassify". Each time you remove the wheel, it is advisable to first process the secret bolts and the wheelbase of any Liquid Key lubrication type 10-15 minutes before the wheel is removed.

3. Check if you have returned the key from "secret" after visiting the binomials or auto-repair shop.

4. Store the special code from the packaging of the secret bolts. A duplicate key can be ordered from the manufacturer for this code.

"Liquid key" is a short term freezing of the bolt or nuts to -30 degrees. The metal is compressing from the cold.

5. If you operate your vehicle on the all-season rubber and do not change it for a long time, at least once every six months, you should twist and round the charmer to avoid the wheel hub.

6. Lubricating the carving of a graphite grease.

What to do if the key to the secret is lost

First, try to overload the secret bolt as much as possible. For this simple wheel of the wheel, it is necessary to tighten the wheel with all possible power. After they start to uncover "secrets" in different ways. The most efficient way is to heat the bolts with the gas welding, and then slowly twirt the bolts, kill it on the tangent and hit it with a hammer. The best thing to do is go to the auto service. Some specialists are able to produce a special key on the blind bolt that will be removed from your secret bolt.
