Are you looking for a professional tire changing solution that will prevent scratches and damage to your valuable alloy wheels? The 3-piece set of protective sockets (17, 19, 21 mm) is an indispensable tool for every DIYer, tire repairer or car mechanic. These high-quality impact sockets are specially designed for safely and effectively loosening and tightening wheel bolts without the risk of damaging the paintwork or material.
Thanks to its robust construction made of top-quality materials and thoughtful protection with a plastic sleeve, this set ensures professional results in every job. Forget about expensive repairs to damaged rims and get the equipment used by professionals. The product is available under the code (SKU) G10510 or V86100 at an extremely competitive price of €24.99.

Why choose professional protective caps for alloy wheels?
When changing wheels, it is common for a metal wrench or impact driver to slip and damage the edge of the bolt hole on an aluminum rim. These protective sockets (cups) solve this problem with an outer plastic sleeve that acts as a shield. As the socket rotates, the plastic sleeve rotates or slides freely against the rim, completely preventing metal-on-metal rubbing.
The set includes the three most common sizes – 17mm, 19mm and 21mm, meaning you’ll be ready to work on most cars, SUVs and light vans. Each size is colour-coded for quick identification and greater efficiency when working in the workshop or home garage.

An indispensable accessory for seasonal tire changes
Whether you change your wheels at home twice a year or run a professional tire shop, this set is an investment that will pay for itself quickly. Aluminum rims are expensive and sensitive to mechanical damage. Using unprotected metal inserts can leave permanent aesthetic consequences on the paintwork of your rims even after the first use.
With a length of 78 mm, you can easily reach even screws hidden deep in sports or multi-spoke rims. The Cr-Mo steel ensures that the bits can withstand the high torque loads produced by modern electric or pneumatic impact wrenches without becoming damaged or deformed.

Same summary

This set of protective sockets in the three most commonly used sizes (17, 19 and 21 mm) is designed for DIYers or those who occasionally undertake maintenance on their own vehicle. The practical plastic-coated protection reduces the risk of damage to alloy wheels, which is especially important for users who value the appearance of their wheels. The set is not intended for demanding professionals with high frequency of use or for the most demanding workshops, where specialized professional equipment makes more sense. Its biggest advantage is its wide applicability in the household, where most everyday tasks require just such a set of basic dimensions.

The kit is also suitable for home garage masters who are looking for a quick solution for occasional tasks with power tools.

Users often trust the Geko brand because it proves to be reliable in tools for daily and occasional use at home.

Answers to frequently asked questions

Are these protective caps suitable for all alloy wheels?

The kit is suitable for most standard alloy wheels with bolt sizes of 17, 19 and 21 mm. For special or non-standard wheels, we recommend that you check the diameter before use.

Can I also use the attachments with an impact power tool?

For occasional use with impact screwdrivers or tools, the bits are suitable, but with very frequent and strong impact use they may wear out faster. If you use an impact tool frequently, we recommend professional versions.

How do I prevent rim damage when changing wheels?

The protective plastic coating of the bits ensures that contact with the sensitive surface of the rim is prevented when used correctly. We recommend that you guide the tools straight and avoid sudden jerks or slipping of the bit.

What should I use to clean the protective attachments after use?

After use, simply wipe the attachments with a dry or slightly damp cloth to remove dust and any oil or grease residue. Do not use aggressive cleaners that could damage the protective plastic coating.

What should I do if one of the dimensions is not suitable for my screws?

If the dimensions provided do not match the correct size, please check the actual diameter of the bolts on your rims. For special or non-standard cases, it is recommended to find a dedicated adapter.
