ᐅ Kallax as a Mini Office – Cordless Drill Damages Shelf Panels!

Hello everyone,

I recently converted a Kallax shelving unit into a small mini office and am generally happy with it. However, while installing the shelves using a cordless drill, I noticed that the screw holes sometimes crack or the wall thickness around the screws gets damaged. The shelf walls are relatively thin and made of coated wood-based material, which apparently isn’t very durable under the stress from the drill.

My question to the community: How can I prevent damage to the shelf walls when screwing them in with a cordless drill? Are there any techniques, precautions, or alternatives to screwing that you would recommend when using a Kallax as a mini office, to firmly secure shelves or panels without damaging the walls?

I appreciate any tips, personal experiences, or construction suggestions!

That sounds really frustrating when all you want is to create something practical, and then you run into such problems. I once had a similar situation when I converted a Kallax into a TV stand. What helped me was using protective washers with the screws so that the screw heads didn’t press directly onto the wood and cause it to splinter.

Maybe that could be an option for you too? Additionally, I always turned the screws slowly from the opposite side beforehand to control the insertion.

What’s important to me is: don’t get discouraged; it’s definitely possible to fix and improve this with the resources you have. 🙂

I use original particleboard screws from IKEA, about 16 mm (0.6 inches) long, with a large head. They are sometimes placed close to the edge

That explains a lot, as the combination of screws that are too long, proximity to the edge, and a large head surface causes stress on the material.

Shorter screws with smaller heads are definitely recommended. Alternatively, you can countersink the holes so that the screw head is recessed, preventing the wood from splitting.

Another fastening option: use corner braces or small metal plates secured with several smaller screws. These distribute the load over a larger area and reduce point stresses.

What about the load the floors or parts of your mini office need to bear? Are higher loads expected there?

One more tip: If you lightly coat the screws with wax or soap before driving them in, the cordless drill will operate more smoothly. This reduces the pressure applied to the wall.

Additionally, I would like to point out the material behavior of Kallax. The panels are made, as mentioned before, of pressed wood composite with a melamine-coated surface, which appears stable but is relatively brittle.

A frequently underestimated factor is the heat generated during screwing – if the cordless drill operates too fast and with too much force, the wood around the screw thread heats up, leading to brittleness and eventual splitting.

My advice:

- Pre-drilling with the correct diameter is mandatory.
- Use the cordless drill at low speed and torque whenever possible.
- At the end, it is better to tighten the screw by hand.
- Alternatively, for the load-bearing parts, consider using wood connectors or special fasteners to transfer the load away from the thin shelf sides.

Last but not least, I would recommend considering the load in the mini office – do you want to place devices or heavy books? This affects the stability requirements and consequently the appropriate connection technique.
