ᐅ Which screws are best suited for reinforcing the construction of IKEA BESTA units?

Hello everyone, I am planning to reinforce my IKEA BESTÅ unit because it is bearing increased weight and feels somewhat unstable. My question is: which screws are best suited to improve the stability of the BESTÅ furniture without damaging the material structure or affecting its appearance? It is important to me that the screws are optimally sized in both length and diameter, and made from a durable material that helps prevent rust. Does anyone have experience with alternative screws or reinforcement methods related to the BESTÅ modular furniture?

Hey! I totally understand your concern – I have also upgraded my BESTÅ with stronger screws to make it more stable! For me, hex head screws with a length of 30-40 mm (1.2-1.6 inches) and a diameter of 4-5 mm (0.16-0.2 inches) have proven ideal. Stainless steel is best to ensure they hold up really well even after years. 😊 Important: Always make sure not to use screws that are too long, otherwise the wood or the cabinet could crack or get damaged. With these screws, you can really feel the difference in stability – highly recommended!

Regarding screws for reinforcing IKEA BESTÅ furniture, I can add some information since this piece is made of particleboard with a thin melamine surface. It is advisable to use screws with a maximum diameter of 4 mm (0.16 inches), as thicker screws can cause the material to crack. The length should be chosen so that the screw grips well in the supporting wood but does not go through the back panel – approximately 25 to 35 mm (1 to 1.4 inches). I also recommend screws with coarse threads, as these provide better hold in wood-based materials. Zinc-plated screws or, even better, stainless steel screws have the advantage of not rusting and not leaving unsightly stains. It is also important to drill a small pilot hole before driving the screws into a new spot to avoid damaging the material. Are your cabinets already screwed together, or are you planning to add new screws in additional places?

Interesting point! However, I wonder whether using larger screws with pre-drilling might generally be recommended to ensure the structure remains secure under heavy loads. The risk of splitting is certainly real, but this can be minimized with a suitable type of screw. Who can guarantee that screws with a 4 mm (0.16 inch) diameter are sufficient if the furniture is supposed to withstand high loads?

Thank you for the suggestion! My construction is located in a living room but will also bear the weight of heavy media equipment. Therefore, both load capacity and durability are very important to me. I wonder if anyone has experience with hardened steel screws or if stainless steel options are the best choice, especially regarding resistance to deformation?

I mostly use stainless steel screws for furniture in living areas! The rust resistance is excellent, and they hardly deform. When it comes to strength, hardened steel screws are a bit tougher, but for the loads on BESTÅ, stainless steel screws are usually more than sufficient. You can also do a small test yourself to check if the screws hold well and aren’t too thick – patience pays off here! 😉
