8-Piece XZN Socket Set (Internal Multi-Tooth) – Professional Tool Set in a Case
Are you looking for a reliable, durable and versatile tool for your workshop or home garage? The 8-piece XZN socket set (internal multi-tooth) under the product code SKU 30204 is an indispensable accessory for every mechanic, handyman or enthusiast of independent vehicle repair. This premium tool set from the Socket wrenches in a case category is specially designed to work with XZN bolts, which are often found in modern cars (especially in VAG brands such as VW, Audi, Škoda, Seat) and in heavy machinery.
The socket wrenches in this set are made of high-quality chrome-vanadium steel (Cr-V), which ensures exceptional strength, wear resistance and long service life. With three different drive sizes (1/4", 3/8" and 1/2") and the included practical metal holder, this tool will quickly become your favorite accessory for precise and safe work. The investment in this set quickly pays off, as it prevents damage to expensive car parts.
Why choose the 8-piece XZN socket set?
XZN or multi-tooth screws require a precise fit of the tool, as using the wrong or inaccurate bits can quickly damage the screw head (so-called "slipped" screws). This professional set offers the perfect solution to this challenge. Each bit in the set is precisely calibrated, which prevents slipping and allows maximum torque to be transmitted without damaging the material.
Thanks to the chrome-plated surface protection, the keys are protected against corrosion, rust and dirt, meaning they will remain in perfect condition even after years of use in demanding workshop conditions. The included metal snap-in guide (holder) ensures that your keys are always tidy, clear and immediately ready for use in your workshop or in the field.

An indispensable tool for auto mechanics and DIYers
If you often work on German vehicles (Volkswagen, Audi, Porsche, Mercedes-Benz, BMW), then you know that XZN bolts are present almost everywhere - from driveshafts, brake calipers, engine parts, cylinder heads to suspension elements. Without a quality set of XZN wrenches, working on these vehicles is practically impossible, as you can permanently damage components with improvised tools.
This 8-piece set ensures you always have the right size wrench on hand, whether you're performing a simple oil change, replacing brake pads, or tackling a more complex undercarriage repair. The compact design and included metal guide make the set extremely easy to carry, making it ideal for field work.
Frequently Asked Questions (FAQ)
What are XZN sockets used for?
XZN (or multi-tooth) sockets are used to tighten and loosen special 12-point screws with an internal profile. These screws allow for the transmission of extremely high torque without the risk of destroying the profile. They are most commonly used in the automotive industry, especially in vehicles from German manufacturers (VAG group), on vital parts such as brakes, drive shafts, engines and chassis parts.
Are these attachments suitable for use with impact tools?
These bits are made of premium chrome-vanadium steel (Cr-V) and are intended for manual use with ratchets, torque wrenches and hand screwdrivers. For use with powerful pneumatic or cordless impact drivers, it is recommended to use dedicated impact bits made of chrome-molybdenum steel (Cr-Mo), as impact tools create specific vibrations that can damage standard Cr-V bits.
How does the included metal holder help?
The included steel snap-in guide with serrated bottom keeps all bits securely attached and organized by size. The holder prevents bits from getting lost while working or during transport. You can easily place it in the drawer of your tool trolley, store it in a case or hang it on the workshop wall, saving you valuable time searching for the right bit.

Answers to frequently asked questions

What types of screws is this set best suited for?

The set is designed primarily for XZN or so-called internal star screws found in cars, some bicycles and household appliances. It is recommended to check the shape of the screw head before use, as these bits are incompatible with Allen or Torx screws.

Is the set suitable for beginners?

Yes, the set is a suitable choice for beginners, as it offers key sizes in one package that are most often sufficient for basic home repairs or car maintenance.

How do I check compatibility with my ratchet or tool?

First, check the drive size (e.g. 1/4", 3/8", 1/2") on your existing ratchet or socket. If it matches the drive in the set, the bits are compatible and can be used without additional adapters.

Can the set be used for professional repairs?

Although it can handle more demanding jobs, this set is more suitable for general, occasional use and basic home workshop equipment. For more extensive professional use, we recommend considering extended or specialized sets.

How do I prevent damage to screws or tools when using the socket wrenches from this set?

Always choose the right bit size for the screw and do not use excessive force. Incorrect bit selection or excessive force may result in damage to the screw or tool failure.
