ᐅ What should I do if the screws for the Pax wardrobe are too short?

Good morning everyone,
I recently assembled a Pax wardrobe but encountered a problem I haven’t seen before: some of the screws included to attach the back and side panels seem too short. More specifically, they have such a shallow penetration depth that I’m concerned it could affect the stability.

My question is: what is the best approach if the screws for the Pax wardrobe are too short? Should I get replacement screws with a better length right away, or are there tips on how to still use or supplement the original screws effectively? Is it possible that I made a mistake during assembly that creates the impression that the screws are too short?

I would appreciate detailed advice on the best way to proceed to ensure the wardrobe’s stability and safety. Thank you in advance for your experience and tips!

Hello Rurifo,

First of all, an important note: The screws supplied by IKEA are usually suitable for the intended assembly parts, as long as these are joined correctly. However, in practice, screws can sometimes seem “too short,” for example if the back panel is not flush with the edge of the carcass or if pre-drilled holes were not placed in the correct position.

Here are a few points you should check systematically:

- Verify whether the back panel (usually an HDF board) is really flush and flat against the back cross and the side panels. It’s common to install the back panel slightly offset or protruding, causing screws to only engage the thin panel layer and thus appear “too short.”

- Could the screws possibly be meant for another component? IKEA sometimes includes sets with several types of screws for different assembly points. Some are shorter, intended for thinner elements.

- If you have checked the screws thoroughly and they are indeed too short, you can use replacement metric screws that are slightly longer. I would recommend keeping the same diameter (usually 4 mm) and only increasing the length. It is important not to overload the material, as this may cause the wood to split.

- Suitable screws can be found at well-stocked hardware stores; it’s best to bring all the screws you have for advice.

Another option is to use plastic anchors if the material tends to fray quickly, or to carefully screw in the screws using a screwdriver combined with a cordless drill to avoid cross-threading.

One more question: Did you follow the instructions exactly, or did you possibly change the order of the steps? That can also affect the fit.

I hope this helps you for now. Feel free to get back to me with more details if you like.

Hello Rurifo,

I would like to add to this and explain more fundamentally why the screws sometimes seem to be just the right length, and what you can do if you still have doubts:

- The construction of a PAX wardrobe is modular, and the screws are precisely matched to the material thicknesses. That’s why they are often carefully calculated but kept short to avoid damaging the wood or penetrating too far through the panels.

- If the screws feel too short, you should check whether all connection points lie completely flat and whether nothing is blocking their entry (e.g., packaging material, protective foil, etc.).

- If you want to use stronger screws, you can opt for chipboard screws with hardened tips, which are commonly available at hardware stores and are especially suitable for joining wood-based materials.

- Sometimes, the key is the correct tightening torque when screwing. Too little tightening can give the impression that the screw is too short because it doesn’t grip properly.

- If you only want to fix the back panel and it is not meant to be load-bearing, often a stapler or special adhesive tape—as sometimes recommended by IKEA—is sufficient.

If you like, I can provide more details on suitable replacement parts.

Hello Rurifo,

I’m adding a brief guide to complement the previous answers, which might help you decide how to deal with screws that are too short for the PAX system:

1. First step: fit the back panel precisely and check the parts. It’s common to forget to align the back panel flush with the cabinet edge.

2. Check the screws: often, different types of screws with varying lengths are included. Sort them out and use the longer screws for the connection points that require more support.

3. Obtain replacement screws:
- Note the dimensions (diameter, length) of the original screws
- Look for chipboard screws with a Phillips head, hardened and rust-resistant, at hardware stores or online
- For example, a 4x40 mm (4x1.6 inch) screw can provide better stability without penetrating through the material

4. Assembly:
- Screw in slowly and straight
- If possible, pre-drill holes with a drill bit to prevent splitting

5. Stability check:
- After assembly, gently shake the cabinet to ensure everything is secure
- There should be no wobbling or creaking

Also, keep in mind that IKEA PAX cabinets rely on a snap-fit system and are generally stable without long screws. The screws often serve mainly to secure the components in place.

Best regards and good luck!

From a technical standpoint, if the supplied screws do not meet the mechanical connection requirements, I recommend replacing them with screws that meet the following criteria:

- Same diameter to avoid damaging the material and to use the existing threaded holes
- Greater insertion depth to ensure increased holding strength
- Corrosion-resistant materials, such as galvanized steel or stainless steel

Furthermore, it is advisable to carefully review the assembly instructions again, especially regarding the positioning of the connection points. There are cases where misalignment of the components causes the screws to seem too short because they do not properly engage in the connection.

If extending the screw length is not technically feasible, additional fastening methods can be considered, such as using dowel screws or angle brackets, which provide extra stability.

It is important not to use screws with a larger diameter when replacing them, as this can enlarge the holes and reduce stability.

A final note: If the wardrobe is intended to carry heavy loads, particular attention should be paid to secure connections. When in doubt, a professional assessment is recommended.

That is a very good point. I would like to add that many users who find the standard connections of the PAX wardrobe problematic have had very positive experiences using small metal angle brackets on the inside of the cabinets.

These brackets are easy to install and better distribute the load, especially if the wardrobe has heavy glass doors or many shelves.

Dowel screws, as vinli mentioned, can also be carefully retrofitted with the appropriate drill to create a stronger wall element.

It is also always recommended to secure the wardrobe to the wall, especially considering the weight of a PAX wardrobe – this increases safety and prevents tipping hazards.

Good luck with your project, and feel free to ask if you have any further questions!
