dra-luHello everyone,
I'm currently planning to modify an Ikea Besta unit and want to make sure I use the appropriate screws to ensure maximum stability and safety. The standard fasteners from Ikea are usually sufficient for regular assembly, but when it comes to modifications—such as adding extra shelves, changing dimensions, or attaching heavy fronts—I'm uncertain which types and sizes of screws are best suited.
Could someone provide specific advice on which screws are necessary for a secure modification of Ikea Besta? In particular, I'm interested in:
- Which type of screws (e.g., particleboard screws, machine screws, wood screws) make the most sense?
- What length and diameter are recommended to avoid damaging the material while still achieving high stability?
- Are there any special screws or alternatives not supplied by Ikea that have proven effective for modifications?
I look forward to your expert feedback to ensure my Besta modification is really stable in the end.

For safe renovations with Besta, I recommend chipboard screws sized 4x40 mm (approximately 5/32 x 1 5/8 inches). They are strong enough and hold well in the material without splitting the wood. Machine screws are only worthwhile if metal brackets or special fasteners are being used.
In this context, it is crucial to consider the properties of the material. The Besta components are made of coated wood-based panels, mostly particleboard with a melamine finish. To improve stability during a renovation without damaging the material, I recommend the following approach:
- Use high-quality particleboard screws made of galvanized steel with a diameter of 4 mm to a maximum of 5 mm (approximately 0.16 to 0.2 inches), depending on the wall thickness.
- The screw length should be chosen so that it penetrates at least 20 mm (0.8 inches) into the wood without coming through the other side. This usually means screw lengths between 40 and 50 mm (1.6 to 2 inches).
- For additional fastening of heavy fronts or drawers, carriage bolts combined with insert nuts are also advisable, as they can withstand higher loads.
It is important to pre-drill before screwing to avoid splitting the particleboard. Without pre-drilling, there is a higher risk of cracks or chipped edges, especially in the thin melamine coating.
Finally, it should be mentioned that special connectors from Ikea (such as the affordable metal brackets with machine screws) often provide stable cross-bracing and can be used as a supplement in the renovation if the original construction is altered.

great question, because if you use standard screws here, things can quickly become loose or even go wrong. My advice: definitely go for high-quality particle board screws; they’re like the cotton T-shirts of screws – they hold well, are flexible, and are usually the best choice 😁.
Sure, sometimes using screws with a larger diameter or length is an option, but it’s always a fine line to avoid splitting the material. And if you’re making a lot of adjustments to the structure, try using metal brackets too – they provide strong support and give the whole thing the stability it needs. So: screws yes, but use them wisely. Good luck with your project!

Additionally, I would like to emphasize that not only the length but also the selection of thread types is important. Particleboard screws have a coarse thread that cuts well into wood-based materials, making them suitable for Besta elements. However, there are also screws with special flanks that cause less damage to coated boards.

Machine screws are only worthwhile when using metal brackets or special fasteners.I agree with this but would like to point out that during renovations, attention must often be paid to tensile and shear forces at certain points. A combination of particleboard screws and machine screws, along with plugs or metal brackets, offers the best long-term stability, although this depends greatly on the specific renovation.
Therefore, it is important to use a combination of tested screw types, appropriate lengths, and targeted reinforcement with metal components. I would recommend not using just one type of screw but planning the renovation as a whole and fastening differently depending on the loads involved.
