Introduction: Why Octavia wheel bolts are no small matter
At first glance, wheel bolts seem to be the simplest part that you can buy “any” in the nearest store. But for ŠKODA Octavia (especially models A5, A7 and restyled FL) the wrong choice is fraught thread breakage in the hub, wheel runout and even disc separation while driving. It's not just the size of the thread - the length, taper shape, material and even the coating are important.
In this article we will look at:
- 🔧 What bolts are on the Octavia from the factory? (articles, sizes, tightening torques).
- ⚠️ Why is replacing with “universal” bolts dangerous? from the store - real cases of breakdowns.
- 🔍 How to distinguish an original from a fake (5 key signs).
- 🛠️ Step-by-step replacement instructions with a checklist and warnings.
We will pay special attention Octavia A7 (2013–2020) and Octavia A8 (from 2020), where the manufacturer changed the bolt requirements due to updated hubs. If you plan to install alloy wheels or winter tires, this guide will help you avoid mistakes that cost hub repairs from 15,000 rubles.
Original ŠKODA Octavia wheel bolts: part numbers and dimensions
Factory bolts for Octavia vary depending on the generation and type of drive. Main parameters:
| Model | Article number (OEM) | carving | Length, mm | Tightening torque, Nm | Note |
|---|---|---|---|---|---|
| Octavia A5 (2004–2013) | N 908 132 02 |
M14×1.5 | 27 | 120 | For steel and alloy wheels |
| Octavia A7 (2013–2020) | N 105 571 01 |
M14×1.5 | 27–29 | 120 (140 for RS) | Bolts with an enlarged head for alloy wheels |
| Octavia A8 (since 2020) | 5Q0 601 159 B |
M14×1.5 | 29 | 140 | With anti-corrosion coating Geomet |
| Octavia RS (all generations) | 1K0 601 159 C |
M14×1.5 | 30 | 140–150 | Reinforced bolts for sports versions |
⚠️ Attention: On Octavia Scout (all-wheel drive versions) bolts with cone angle 60°, rather than the standard 90°. Installing the wrong bolts will result in uneven tightening and vibrations at speeds above 100 km/h.
To check originality, pay attention to:
- 🔰 Marking - there must be a logo on the hat VW Group (letters
VWorSKODA). - 🎨 Coverage — the originals have a matte gray color (
Geomet), fakes often shine. - 📏 Thread accuracy - check with a caliper: the thread diameter should be
13.85–13.95 mm.
- Original (OEM)
- Analogues (Febi, SWAG)
- Universal from the store
- I don't know which ones are worth
Analogs of original bolts: what to choose if there is no money for OEM
High-quality analogues will cost 2–3 times less than the original, but it is important to choose a trusted manufacturer. Best options for Octavia:
- 🔧 Febi (article
27120) - German quality, suitable for all generations. Price: ~300 rubles / piece. - 🔧 SWAG (article
30 92 7120) - similar to Febi, but with improved anti-corrosion coating. - 🔧 TRW (article
JBW120) - used on conveyors VW Group as understudies. - 🚫 Avoid brands
Automega,SASIC— cases of thread failure are frequent.
💡 Tip: When buying analogues, take bolts 1–2 mm longer original. This will compensate for possible shrinkage of the threads in the hub and prevent “under-torque”. For example, for Octavia A7 instead of 27 mm, take 29 mm.
Before purchasing, check the bolts with a magnet - originals and high-quality analogues are not magnetic (stainless steel with additives is used).
Tightening torque: why 120 Nm is not always correct
Official tightening torque for most Octavia — 120 Nm. But there are nuances:
- 🔧 For Octavia RS and models with forged wheels the moment is increased to
140–150 N·m. - 🌡️ When replacing bolts with aluminum hubs (for example, on Octavia A8) the moment is reduced to
110 Nmto avoid thread stripping. - ❄️ For winter tires (if the wheels are steel) the torque is left standard, but checked after 500 km.
⚠️ Attention: Using an air impact wrench without a torque wrench results in constriction in 80% of cases. The consequences are broken threads or deformation of the brake disc. Always tighten the bolts manually torque wrench!
📌 Tightening order:
- Tighten the bolts "crosswise" firmly
50 Nm. - Lower the vehicle to the ground (suspension must be loaded).
- Reach the final moment (
120 Nmor another according to the table). - Check the torque after 100–200 km.

When to change bolts: 5 signs of wear
Wheel bolts are consumables, but many owners Octavia they forget to check them. Replacement is required when:
- Thread failure — even partial wear of the coils reduces the reliability of fastening by 30%.
- Corrosion — rust on the head or thread increases the risk of “sticking” of the bolt.
- Cone deformation — if the bolt has “grown in” to the disk, it needs to be replaced (otherwise the wheel will break).
- After the accident — even with a slight impact, the bolts can get microcracks.
- After 100,000 km — recommended replacement interval for prevention.
🔍 How to check: Take a new bolt and compare it with the installed one. If the thread of the old bolt is “dull” or has burrs, it’s time to change it. Also note color: darkening of the metal indicates overheating (for example, after heavy braking).
What happens if you don't change the bolts?
Ignoring bolt wear leads to:
- Unscrewing the wheel while driving (especially dangerous at speeds above 80 km/h).
- Deformation of the brake disc due to uneven tightening.
- Breakage of the thread in the hub, which will require its replacement (cost - from 8,000 rubles per part + labor).
In 2022, 12 accidents were recorded in Russia due to loose wheels, 3 of which involved ŠKODA (data from the traffic police).
Step-by-step instructions: how to replace wheel bolts on an Octavia
To work you will need:
- 🔧 Torque wrench (range
40–200 Nm). - 🔧 Socket wrench on
17 mm(or19 mmfor RS). - 🔧 Copper grease (
Loctite 8008or analogues). - 🔧 Metal brush for cleaning threads.
Step 1. Preparation
Park the car on a level surface, engage the gear (or Parking for automatic transmission) and place chocks under the wheels. Do not use the jack without safety stands! Raise the car and remove the wheel.
Step 2: Clean the threads
Use a brush to clean the threads in the hub from dirt and corrosion. If heavily soiled, use a cleaner WD-40, but then wipe with a dry cloth - oils and liquids reduce the tightening torque.
Step 3: Install new bolts
Apply a thin layer of copper grease to the bolt threads (not the head!). Insert the bolt into the hole and tighten it by hand until it stops. Then use a torque wrench in a criss-cross pattern.
⚠️ Attention: If the bolt is tight, don't use force - check thread compatibility. Forced tightening can break the coils in the hub!
Step 4. Check
After lowering the vehicle, check the tightening torque again. Drive 10–15 km and re-check the bolts - they may have “settled”.
Using an impact wrench to tighten wheel bolts is strictly prohibited! Even experienced craftsmen cannot control the moment “by eye”, and over-tightening leads to deformation of the hub.
Common mistakes and how to avoid them
Even experienced car owners make mistakes when working with bolts. Let's look at the top 5 mistakes and their consequences:
- Using "universal" bolts
Bolts with
M12 threadorin steps of 1.25(instead ofM14×1.5) do not provide sufficient fixation. Result: the wheel unscrews while driving or a runout appears. - Tightening by eye
Without a torque wrench, 90% of owners overtighten bolts. This leads to brake disc deformation (replacement cost is from 5,000 rubles per disk).
- Ignoring Corrosion
Rusty bolts “stick” to the hub. When you try to unscrew them, the slot breaks off or the key breaks. Output: process
WD-4012 hours before replacement. - Mismatch between the bolt cone and the disc
If the bolt is
60° cone, and the disk is designed for90°, the wheel will “walk”, which will lead to uneven tire wear. - Lack of lubrication
“Dry” threads increase friction, which is why the actual tightening torque may differ from the specified one by 20–30%.
📌 Tip for saving: If the bolts are stuck, do not try to cut them off with a grinder - this will damage the hub. Use special puller (for example, KUKKO 21-1) or contact service.
FAQ: answers to frequently asked questions
Can bolts from other brands (eg VW Golf) be used?
Yes, but with reservations. Bolts from VW Golf, Audi A3 or SEAT Leon (on the platform MQB) suitable for Octavia A7/A8, since they use the same thread M14×1.5. However for Octavia A5 (platform PQ35) bolts with a different cone angle are needed (90° instead of 60°). Always check the compatibility chart!
What to do if the thread in the hub is broken?
If the thread is partially torn off (1-2 turns), you can try screw in a bolt with a longer thread (for example, 30 mm instead of 27 mm). If the breakdown is serious:
- Install repair sleeve (for example,
Time-Sert). - Replace the hub (cost - from 8,000 rubles).
Do I need to change bolts when changing wheels seasonally?
No, if the bolts are in good condition. However:
- Check tightening torque after each “change of shoes”.
- If the bolts are corroded or deformed, replace them.
- For alloy wheels use bolts with enlarged cap (article
N 105 571 01).
Which bolts are suitable for tuned wheels (with offset ET35–ET40)?
For wheels with non-standard offset you need extended bolts (for example, 35–40 mm). Please note:
- 🔧 Thread length - it should be 3–5 mm longer than the standard one.
- 🔧 Hat shape — for deep disk caps, bolts with corner nut (article
WHT 005 159). - 🔧 Material - choose bolts from alloy steel (labeling
10.9or12.9).
How often should bolts be checked for tightness?
Recommended schedule:
- 🔧 After replacing wheels or bolts - after 100 km.
- 🔧 When changing tires seasonally - after 500 km.
- 🔧 When driving off-road - every 1,000 km.
Use torque wrench — even a slight weakening (10–15 Nm) can lead to the wheel unscrewing.
