Removing the hub on cars ŠKODA - a procedure that every owner faces sooner or later. One of the key points here is the correct choice of tool, namely 12-point socket 24 mm. This part seems simple, but errors in its selection or use can lead to breakage of the bolt edges, damage to the hub, or even injury. Why 12-sided and not the standard 6-sided? What is the difference between the heads for Octavia A5 and Kodiaq? And how can you avoid running into a fake that will break at the first effort?

In this article we will look at unique features of ŠKODA wheel boltsthat require special tools, we compare heads from different manufacturers (including Hazet, Stahlwille and budget analogues), and we will also give step-by-step instructions for removing the hub without the risk of damaging the threads. We will pay special attention to typical mistakes that even experienced craftsmen make - for example, why you can’t use an impact wrench with the wrong head or how to recognize “tired” bolt threads before they break.

Why does ŠKODA need a 12-point 24-point head?

Hub bolts for most models ŠKODA (from Fabia up to Kodiaq) have a non-standard configuration: instead of the usual 6 faces, they use 12-sided design. This is not a whim of engineers, but a necessary measure:

  • 🔧 Increased load: 12 edges distribute force more evenly, reducing the risk of breakage at high torque (up to 200–250 Nm for some models).
  • 🔄 Ease of installation: the head fits onto the bolt with less play, which is critical when working in cramped conditions (for example, on the rear hub Octavia with brake caliper).
  • 🛡️ Vandalism protection: the non-standard profile makes it difficult to unscrew the bolts without a special tool.

Important: on some models (for example, ŠKODA Yeti until 2013) there are bolts with internal 12-sided (type E14 or E16). They are often confused with external ones, but they require a completely different tool - Torx E-profile. Always check the bolt type before purchasing a head!

Interesting fact: at the factory ŠKODA in Mladá Boleslav, pneumatic impact wrenches with socket heads are used to tighten hub bolts Hazet 900SP-24, which can withstand up to 300 Nm without deformation. This clearly demonstrates what safety margin a quality tool should have.

📊 What tool do you use to work on the hubs?
  • Only original heads (Hazet, Stahlwille)
  • Budget analogues (Jonnesway, Nussbaum)
  • Universal attachments (with adapters)
  • Didn't work with hubs

Head sizes and types: what to choose for your ŠKODA model

Not all 12-point 24-point sockets are the same. The difference may be:

  • 📏 Planting depth: for ŠKODA Superb with long bolts you will need a head with an increased height (for example, Stahlwille 720/24), whereas for Fabia The standard one will do.
  • 🔩 Shank type: 1/2" (for powerful gates) or 3/4" (for professional impact wrenches).
  • 🛠️ Material: chrome vanadium steel (Cr-V) or chromium-molybdenum (Cr-Mo) for extreme loads.
Model ŠKODA Hub bolt type Recommended head Tightening torque (Nm)
Octavia A5/A7 External 12-point, M14×1.5 Hazet 900SP-24 or Stahlwille 720/24 180–200
Kodiaq (2017–present) External 12-point, M14×1.25 Stahlwille 720/24 (deep) 210–230
Superb 3V External 12-point, M14×1.5 Hazet 900SP-24 + extension 200–220
Fabia NJ External 12-point, M12×1.5 Jonnesway S2412 (budget) 120–140

⚠️ Attention: on cars with a system 4Motion (all-wheel drive) the tightening torque of the hub bolts is higher by 15–20%! Using a head without a safety margin (for example, cheap Chinese analogues) can lead to its destruction when tightened.

Tip: if you are working with ŠKODA on a lift, select heads with magnetic holder (for example, Nussbaum 2412M). This will prevent the bolt from falling into the wheel arch niche, which is especially important for models with a dense suspension layout (for example, Kamiq).

Top 5 head manufacturers: comparison by price and quality

The market offers 24-point (12-point) heads ranging from 300 rub. up to 5,000 rub.. The difference is not only in price, but also in resource, accuracy of fit and corrosion resistance. We tested 15 brands and selected the best:

  1. Hazet 900SP-24 (Germany, ~4,500 rub.)

    Quality standard: hardened steel Cr-V, laser engraving of size, guarantee against edge breakage. Suitable for professional use with impact wrenches.

  2. Stahlwille 720/24 (Germany, ~5,000 rub.)

    Premium segment: coating Stahlwille-Surface protects against corrosion, increased head height for deep wells. Ideal for Kodiaq and Superb.

  3. Nussbaum 2412M (Taiwan, ~2,200 rub.)

    Best price/quality ratio: magnetic lock, torque resistance up to 250 Nm. Popular among car repair shops.

  4. Jonnesway S2412 (Taiwan, ~1,500 rub.)

    Budget option for rare use. The downside is that it wears out quickly when working with rusty bolts.

  5. FORCE 2412-12 (Russia, ~800 rub.)

    Suitable for one-time work, but requires care: when the torque exceeds 180 Nm deformation of the edges is possible.

⚠️ Attention: Avoid heads without size and country of origin markings! Counterfeits Hazet or Stahlwille often made from low quality steel 45#, which breaks at the first effort. Check the weight of the tool - original heads weigh at least 200–250 g.

💡

Before purchasing, inspect the head for burrs inside the edges. Even minor defects can cause the bolt to break when tightened.

Step-by-step instructions: how to remove a ŠKODA hub using a 12-point socket

The process of dismantling the hub requires accuracy and consistency. Below are universal instructions suitable for most models. ŠKODA (exceptions are noted separately).

Jack up the car and remove the wheel|Clean the wheel bolt from dirt with a wire brush|Treat the threads with penetrating lubricant (WD-40, Liquid Wrench)|Check the brake caliper for serviceability (remove it if necessary)-->

  1. Fixing the car

    Place wheel chocks under the rear wheels (even if you are working from the front!). Raise the car on a jack and secure it on stands. For Octavia A7 with 4Motion system, be sure to lock the rear axle!

  2. Removing the cap and caliper

    Remove the hub protective cap (if equipped) and unscrew the caliper guides. Hang the caliper on a wire - do not leave it hanging from the brake hose! On models Kodiaq It may be necessary to remove the ABS sensor.

  3. Unscrewing the hub bolt

    Place a 12-point socket on the bolt and use a socket with an extension. Do not use an impact wrench in the first stage! Loosen the bolt by hand first, then you can use air tools. The lift-off moment can reach 250–300 N·m due to corrosion.

  4. Removing the hub

    After unscrewing the bolt, remove the hub from the axle. If it gets stuck, use a puller or gently tap it with a hammer through a wooden spacer. On Superb 3V, be careful with the wheel position sensor!

⚠️ Attention: If the bolt does not budge even after treatment with lubricant, do not increase the length of the lever beyond 50 cm - this can lead to a breakdown of the edges. In such cases, use heating (gas burner) or specialized means (for example, PB Blaster).

What to do if the edges of the bolt are torn off?

If the edges of the hub bolt are torn off, do not try to unscrew it with a smaller socket (for example, 23 mm) - this will only make the problem worse. Optimal solutions:

1. Use bolt extractor (for example, Irwin Bolt-Grip).

2. Weld a nut onto the bolt and unscrew it with a wrench.

3. As a last resort, drill out the bolt with a metal drill (the diameter is 1–2 mm smaller than the thread) and use a tap to restore the thread.

Common mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when working with hubs ŠKODA. Here are the most common ones and ways to prevent them:

  • Using a 6-point socket: causes the bolt edges to break off. Always check the markings - it should indicate on the head 12-POINT or DOUBLE HEX.
  • Tightening without a torque wrench: an overtightened bolt may burst when moving, and an undertightened bolt may turn. For ŠKODA It is critical to observe the point indicated in the table above.
  • Ignoring Corrosion: a rusty bolt requires pre-treatment with lubricant and acidification time (minimum 30 minutes).
  • Work without fixing the caliper: on models with ESP (for example, Octavia RS) this may damage the brake hose.

Pay special attention re-tightening after replacing a hub or bearing. By car ŠKODA with the system XDS (electronic differential) Uneven tightening of the bolts may cause false operation of the system. Always follow the diagram:

  1. Hand tighten the bolts until they are tight.
  2. Tighten with a torque wrench until 50% from the required moment.
  3. Finally tighten to full torque in a criss-cross pattern.
💡

On ŠKODA vehicles with aluminum hubs (e.g. Octavia RS), the reuse of bolts is prohibited! Always install new bolts when removing the hub.

Alternative methods: when the head does not help

Sometimes even a high-quality 12-point socket cannot cope with a stuck bolt. In such cases, alternative methods will be useful:

  • 🔥 Thermal method: Heat the hub with a gas burner for 2–3 minutes, then try to unscrew the bolt. Thermal expansion will weaken corrosion.
  • 🔨 Percussion technique: Apply a few sharp blows to the head with a hammer (through a wooden block), then try to unscrew it. The vibration helps to “tear” the bolt out of place.
  • 🧲 Chemicals: specialized rust solvents (for example, Kroil) penetrate deeper than WD-40. Exposure time - no less 12 o'clock.
  • ⚙️ Special tools: For bolts with stripped edges, use extractor head (for example, Irwin 1964535), which “bites” into the metal.

On models ŠKODA with the system Haldex (all-wheel drive) be careful with heat - high temperatures can damage the drive seals. In such cases, it is better to use chemical methods or contact the service.

⚠️ Attention: If the bolt bursts when unscrewing, do not try to drill it yourself without experience! The remaining debris can damage the threads in the hub, and it will have to be completely replaced. In such cases, it is optimal to use left hand drill and a tap for cutting new threads.

FAQ: answers to frequently asked questions

Can I use an impact wrench with a 12-point socket?

Yes, but only if the head is designed for shock loads (it must be marked IMPACT). Regular heads (eg Jonnesway S2412) when used with a wrench, they quickly become deformed. For ŠKODA Kodiaq we recommend Hazet 900SP-24 Impact.

What is the difference between the bolts on the front and rear hub?

On the front hub the bolts are usually shorter (length ~30 mm), and on the back it is longer (~40–50 mm). Also on the rear axle (especially on models with 4Motion) tightening torque is higher by 10–15%. Always check the manual!

Do I need to replace the hub bolt after removal?

For most models ŠKODA (except Octavia RS and Superb Sportline) The bolt can be reused if the thread is not damaged. However, on vehicles with aluminum hubs, the bolts must be replaced for new ones!

What lubricant should I use on the bolt before installation?

Use copper paste (for example, Liqui Moly Kupfer-Paste) or graphite grease. Do not use lithol or solid oil - they “tan” at high temperatures and may complicate future dismantling.

Will a 24mm socket fit a VW hub? Are ŠKODA and Volkswagen on the same platform?

Partially. For most models VW (for example, Golf or Passat B6) the same head will do, but there are exceptions:

  • VW Touareg - a head with increased height is required (30 mm).
  • VW Amarok - bolts with internal 12-point head (E18).

Always check by VIN code!
