In detail with all the nuances about wheel bolts for the VAZ 2109

Happy Monday everyone! Yesterday I went through the front suspension. Having tinkered with it enough, right at the end of the work, I tore off the thread of the wheel bolt, tightened it by hand as usual, and when I started pulling it, it immediately turned, the attempt to replace the bolt did not lead to success, the other bolt also turned. How to treat? So far I see two options: 1. Drive the thread with a tap (remind me, the thread seems to be M12 and what is the pitch?), but it is unlikely that this will help 2. Replace. The question here is what to replace, where exactly is the thread cut? I looked here and it’s not clear what part is needed. The one without a number (what is her name)?

What other options are there? Please share your experience?

Z.Y. Along the suspension bulkhead itself. If you don’t know when, who and how the last time someone climbed into it, it’s better to immediately prepare the upper arm and its axis. 200 rub. It’s not the kind of money to spend a few extra hours under the car, unsuccessfully trying to tap, soak, pick out the inner clip of the silent block (the grinder rules). I’ll prepare the right side in advance so that on Sunday evening before closing I won’t have to run to the store in hopes of being in time.

You will find such a tap with a very small pitch. But if the thread has been torn off shallowly, then walking it along the thread may help.

Everyone knows that bolts are used to secure wheels on many domestic cars, in particular on the “nine”.

Without exaggeration, the life of the driver and passengers depends on the wheel fasteners. Therefore, you need to select wheel bolts for the VAZ 2109 with all seriousness and it is better to purchase them from official dealers of automakers. Only correctly selected wheel bolts guarantee reliable fixation of the wheels.

What types of wheel bolts are there?

Let's look at what a VAZ 2109 wheel bolt is.

Standard fasteners have:

• hex head;
• conical clamping part;
• threaded part.

Moreover, the edges of the head turn into a cone. M12 thread with pitch 1.25 and thread length 22 - 24 mm. Thread pitch is a very important parameter. If you forcefully screw in bolts with a different pitch, you can ruin the threads in the hub, and then you will have to change it.

Such hardware is used for wheels with stamped discs. If cast (light alloy) wheels are used, then for the VAZ 2109 the wheel bolt must be longer (27 - 33 mm). Chrome plated with a conical rotating washer is often used. This washer, located under the head, protects the surface of the disc when the bolt is tightened. Its threaded part must completely fit into the hole in the hub, but no more, so that when the wheel rotates, the bolts cannot touch stationary parts.

It is worth emphasizing that you cannot put old stamping hardware on new alloy wheels. In this case, the bolts can easily unscrew under load and the wheel will fall off while driving. I don’t even want to talk about the consequences.

The clamping part of the bolt can be spherical, but it must coincide with the profiles of the holes in the wheel rim to ensure wheel alignment.

Wheel bolts for the VAZ 2109 are made with a hex head for a 17 or 19 wrench. There are also lightweight hardware with a hollow head for a hex key. There are also bolts in which the head has an internal 10-pointed star. These require a non-standard key.

Selection principles

The selection of wheels is carried out taking into account the design features of the vehicle and operating conditions, assessing the influence of many factors.

A car with 15 rims looks beautiful, but requires the use of low-profile tires, otherwise the tires will rub against the wheel arch protection. Operation in off-road conditions, maximum loading of the trunk with this option threatens with negative consequences.

Wide rims with long overhangs increase stability, but tend to be very dirty in bad weather conditions. The large curb weight of the vehicle leads to friction between the tires and the wheel arches.

Choosing free rims means replacing car tires. You should take into account the acceptable tire sizes recommended by experts for the VAZ-2107:

Pressing surface

According to the classification of the landing zone, fasteners are distinguished:

• with a spherical connecting part;
• with conical clamping part. Models are manufactured with and without gaps in the pressure zone. Headrests 1.3 mm.

Many car enthusiasts wonder which cone or ball is best. In each case, it is recommended to seek the help of a specialist to select bolts for alloy wheels. He will advise what will be better.

How to avoid wheel theft

To protect wheels from theft, some use “secrets,” as they are called. This is a bolt that cannot be unscrewed with standard tools, but only with an individual special key, available only to the owner of the car.

Various methods are used to protect such fasteners. For example, the head of a bolt can be made in the shape of an irregular polygon or a completely arbitrary figure; one of the profiles is sometimes shifted to the side. A perforated profile with holes of various diameters and depths is also used. You cannot determine the reliability of secrets by looking at their profile; it is more important to use products from proven and reliable manufacturers.

Usually, in order not to ruin the secret bolt, it is tightened with less force. Because of this, such wheel bolts in the VAZ 2109 are placed one on each wheel. Unfortunately, in our country there are still people who like to “take off” your car’s shoes, so the topic of secret locks remains relevant for now.

All these secrets make it difficult for lovers of easy money to remove the wheels, they make it difficult. Because if you have time, you can unscrew everything, but thieves have little time.

Therefore, in order to most effectively protect your wheels, you should follow several rules.

1. It is better to buy expensive secrets, this helps to avoid matching products. Because when producing unique secrets, after some time the cycle repeats, and there is some chance of repetition of parts. But in expensive products such coincidences are excluded.
2. If you buy alloy wheels, it is better to choose ones in which the secrets would be “recessed” inside the disk rather than on the surface. They are more difficult to unscrew.
3. It is worth purchasing bolts with a flat pattern at the top of the head, which is not sharpened to a key. (For example, an asterisk or a heptagon). That is, the drawing should be as unusual and flat as possible.

The price on the Internet for regular wheel bolts is from 14, and for “secret” ones from 160 rubles.

Sometimes car enthusiasts use bolts for VAZ 2109 wheels with an offset center. They are easy to find in online stores. Such bolts are used if there are no original disks and others have been installed with slight differences. The eccentric bolts allow you to align all the holes and securely fasten the wheel.

Bolts are made from different materials. This can be steel with an admixture of molybdenum or steel coated with nickel, chromium, etc., sometimes even titanium. Coated bolts have a nice appearance. But don’t think that this is the best choice. The problem is that any bolts are susceptible to corrosion. And the technology of nickel or chromium coating with sufficient stability has not yet been created. After a year, coated bolts will inevitably lose their beauty. Therefore, the appearance of the bolts is practically unrelated to their operational data. The most important factors are strength, thread pitch, length and type of bolt head.

To change wheels yourself, you need to know how to properly unscrew and tighten the wheel bolts. To do this, you should look at the photos and videos. There are a lot of such materials on the Internet. There are also instructions online for tightening bolts using a torque wrench. It is especially important when installing new bolts after approximately 50 km to check the tightness of all bolts. Most likely, some of them will have to be tightened up!

Wheel bolts are used by European car manufacturers. Nuts are used in the Japanese and Korean automotive industries. When choosing mounting elements, you should have an idea of ​​their technical features.

The appearance of the car, among other things, depends on the wheels installed on it. Elegant alloy wheels can transform the simplest and most inconspicuous car, giving it originality. VAZ car owners have access to a large selection of wheel rims:

For each type, you must purchase the appropriate bolts to securely secure the wheel. These fasteners are made from a variety of materials:

• black metals;
• metals with the addition of zinc or chromium;
• nickel alloys;
• alloys with molybdenum, etc.

When choosing wheel bolts, consider not only their appearance and strength, but also their size: length, head type, thread size and pitch.

Types of fasteners

Here are the types of fasteners needed for alloy wheels:

1. Bolts are metal rods with a screw thread at the end. Used to connect detachable elements.
2. Nuts are round-shaped parts designed to fasten elements by screwing a metal die onto threaded rods.

Steel, aluminum or titanium alloys are used to produce products.

Titanium bolts are distinguished by high quality indicators. Black bolts for alloy wheels are made from steel with the addition of molybdenum or steel with a chrome or nickel coating.

Characteristics of bolts and nuts

Bolts and nuts differ in design features, so the choice is determined by the type of disk. The stamped disc is made from a durable type of steel. Moreover, it has a small thickness at the point of attachment to the central part of the rotating part. For an optimal connection, the bolt and nut must have a flat surface. The composition of cast wheels includes relatively light alloys. They have reduced reliability characteristics. The fastening system of the products is made in the form of a cone.

Thread

When purchasing bolts, you should pay attention to the threaded part. Not all elements have the same thread pitch. More often there are hardware with a thread pitch of 1.25 and 1.5 mm with a diameter of 12 or 14 mm. It is recommended to purchase new wheel bolts complete with rims or take into account the requirements of the car manufacturer's instructions.

Thread length

To select a bolt of the required length, the easiest way is to try it on site. This technique does not work if the bolt is coated with a coating that is difficult to scratch. Then another option will do; you will need to count the number of revolutions when unscrewing the old bolt. Next, the length of the threaded pin is divided by the resulting figure. The result will be the required length of the fastener.

By size, fasteners are divided into:

• short - used for fixing stamped disk products;
• long - used for tire mounting of alloy wheels.

Pressing surface

In accordance with the classification by landing zone, fasteners are distinguished:

• with a spherical connecting part;
• with a cone-shaped clamping part. Models are produced with and without gaps in the pressure zone. The size of the headrests is 1.3 millimeters.

Many motorists wonder what would be most suitable - a cone or a sphere. In each individual case, in order to select bolts for alloy wheels, it is recommended to seek help from a professional. He will advise what will be better.

Coating

Bolts and nuts are chrome and zinc plated. The surface layer does not protect against corrosion processes. Models with decorative coating retain their visually attractive appearance for no more than a year. Fasteners with a protective and decorative shell are more expensive.

Other parameters of VAZ 2115:

Thread M14 x 1.5 means:

M14 – thread diameter 14 (mm); 1.5 — thread pitch (distance between adjacent threads).

Caution: the above data are the official figures of the manufacturer, however, please note that the information is for reference only and does not guarantee absolute accuracy.

How to measure yourself

Measurements must be as accurate as possible, since the indicators differ in close values ​​with a distance of a couple of millimeters, for example, 98 and 100 or 110 and 112, and they are not interchangeable. To eliminate errors, it is recommended to use a caliper or ruler.

Adjacent holes

Here's how to determine the distance between bolt holes. The dimensions of the circle on which the holes are located are taken. The diameter is determined using compatibility tables or by measuring using a ruler. The resulting distance between adjacent fasteners should be multiplied by a factor that depends on the number of holes. The circumference of a VAZ is 9.8 cm, and that of passenger cars is 139.7 millimeters.

Full and abbreviated bolt pattern formula

Manufacturers provide detailed wording that reflects all important meanings. Motorists use abbreviations that do not fully describe the product.

Abbreviated

PCD (Pitch Circle Diameter) is a short formulation that includes two parameters. It is indicated: 4×98 – wheel bolt pattern on a VAZ-2110. The number of four indicates the number of bolt recesses. The number 98 was obtained as a result of the transverse method of measuring their circumference.

Full

Let's look at an example: the full bolt pattern formula is indicated on the rim: 7.5 J×15 H2 5×100 ET 40 D 54.1.

Decoding of alphanumeric groups means:

• 5 JX 15 – rim width 7.5 inches and diameter 15 inches;
• X – indicates that the disc is made by casting or forging;
• J – it is recommended to use the product on single-wheel drive vehicles;
• JJ – marking of all-wheel drive models;
• H2 – the number of protrusions that secure the tires. Models with one protrusion - H1. Absence of protrusions - marking AN;
• Hump ​​- indicates high-quality rubber retention; this feature eliminates depressurization.

Lada Granta 219x Restyling 2022 1.6i 98

Generation: 219x Restyling Engine: VAZ-21126, I4, Gasoline Power: 98 hp (72 kW) Equipment: Comfort, Luxe

Wheel bolt pattern parameters

What wheel sizes does the manufacturer recommend to install?

The Lada Granta 219x Restyling 2022 1.6i 98 is equipped with 5.5Jx14 ET35 rims assembled with 175/65 R14 82H tires as standard. Where:

• 5.5J - rim width in inches;
• 14″ — tire diameter in inches;
• ET35 - disc offset in millimeters.

The vehicle tire marking 175/65 R14 is deciphered as follows:

• 175 — profile width (cross section of the tire) in millimeters;
• 65 — profile height as a percentage of its width;
• R - radial cord winding;
• 14 is the tire diameter in inches.

In addition, information about its load capacity and speed parameters can be printed on the rubber - load index and speed index. The load index is a two- or three-digit number; the speed index is indicated in Latin letters, for example 82H:

• 82 - maximum permissible tire load 475 kg;
• H — maximum permissible vehicle speed is 210 km/h.

Using the recommended tire sizes will help you avoid problems with handling, safety and other difficulties. What non-standard sizes can be supplied? Refer to the table; it indicates possible acceptable alternative sizes for tuning. Although there are other options that we have not described in the table. For example, wider discs of the same diameter. Or install wheels of the same width, but with a larger diameter, which is quite popular among car owners. The choice of discs is huge; you can find copies with the same parameters, but with an overhang 1-2 millimeters more or less. It is not possible to list all the options.

Consequences from another bolt pattern

Using inappropriate bolts is a safety hazard. When a bolt pattern occurs, an axial displacement of the entire wheel relative to the hub occurs. At high speeds, the wheel spins unevenly, the car will shake, which is accompanied by a beating in the steering wheel.

When installing wheels, car enthusiasts often encounter such a problem as a discrepancy in the diameter of the fasteners. In this case, eccentric bolts with a movable conical part are suitable, which will eliminate discrepancies in size.

Tightening fasteners on alloy wheels

Before installing the bolts into the mounting recesses, it is recommended to treat the hardware with graphite lubricant. As a result, when it comes into contact with the disk, the head of the bolt or nut will rotate and make full contact. This will prevent blocking during starting power due to friction between the disc and the mounting system. Bolts are produced that compensate for minimal deviations in fastener dimensions. A loose connection will lead to cyclical failures in the fastening system; the bolts and nuts will begin to unscrew themselves.

Locking bolts for alloy wheels

Secret bolts for alloy wheels are another subtype. If you install locks, car tires will be protected from theft. You won't be able to remove the wheel with a regular wrench. To unwind the secrets, you will need a key that comes with them in one set.

When selecting fasteners for wheels, you should remember that cast products are relatively thick. Accordingly, longer bolts are selected for them than for stamped discs.

Characteristic differences

Wheel bolts for stamped wheels differ in length and material. Usually good steel is used, which has several types of coating:

It must be said that any type of coating is only a top protective layer. Therefore, it cannot provide reliable protection against corrosion.

To give the stamped disc a more aesthetic appearance, chrome-plated bolts are ideal. If you properly care for your car and operate it normally, the bolts will never rust.
