Hello everyone, I have a question about the durability of Malm screws with frequent use. I have noticed that this type of screw often becomes loose over time, especially with regular stress, for example in furniture or assemblies. I am interested in why this happens, even though the screws should normally hold firmly. Is it due to material fatigue, the thread design, environmental factors, or perhaps the way the screws are installed in Malm furniture? Are there technical or physical explanations for why Malm screws tend to loosen with frequent use? I look forward to your detailed assessments and explanations!
Hey, great thread! 🙂 I can definitely confirm that constant movement is the biggest enemy of Malm screws! I use those pieces every day and had to keep tightening them.
What I also recommend is not focusing too much on torque when assembling, but rather tightening evenly. This helps prevent uneven loosening later on.
And of course, check the screws occasionally, especially if you notice the furniture becoming a bit wobbly. That saves you trouble!

Apply threadlocker adhesive.Exactly! Using a threadlocker is an excellent measure. However, it is important to choose one that is medium strength, so it can be removed if necessary.

Installation quality: If the screws are not perfectly perpendicular or the pilot hole is too large, the required counterpressure is missing.I would like to add to that: drilling pilot holes is also crucial, especially to prevent the material from splitting and the screw from losing its holding power. A hole that is too large can quickly cause loosening because the thread will not have a firm grip.
A small addition from my side: Sometimes it helps to treat the screws with a little dry wax or soap before inserting them. This reduces friction and allows the screws to be driven in more easily and securely.
But be careful: not too much – otherwise the connection might not hold properly! Use just a little so that the screw can set firmly.
This is how I did it with some furniture, and it significantly reduced the loosening of the screws.

Therefore, it should be used with caution for connections that are frequently loaded or moved.
From a technical perspective, using a proper thread locking method or spring washers is the safer option for dynamic loads. Consistently retightening after the initial installation is also essential to ensure lasting stability.
