Hello everyone,
Recently, I have noticed that the screws in several Malm furniture pieces tend to loosen relatively quickly, even though I usually tighten them with the recommended torque. I’m curious about the reasons behind this, as it affects the stability of the furniture.
Could it be due to material properties, the design of the joint, or perhaps the type of screw itself? Are there known weak points with Malm screws that cause them to become loose?
I’m specifically asking why Malm screws often loosen even when properly tightened, and what can be done to prevent or fix this issue.
Looking forward to your experiences and explanations.

If you tighten the screws too much, the material around the threads can tear out, causing the screws to become loose. Manufacturing tolerances can also result in the joints becoming less secure after frequent use.

Essentially, with the Malm system, it is important to note that the screws are often fastened into pre-made dowels or small connectors. These joints are designed for easy assembly and low production costs.
The materials used, such as MDF or particleboard, have lower density and strength compared to solid wood, which causes them to deform more quickly under load or when screws are repeatedly tightened and loosened.
A key step to prevent loose screws is careful tightening with the appropriate tools (ideally a torque wrench or a bit with torque control). Additionally, it is important to avoid repeatedly loosening and retightening the screws, as this weakens the fastening points.
An alternative for frequently loosening screws is to use screw locking compounds (e.g., threadlocker or loctite) or to repair the screw holes—for example, with wooden dowels, wood glue, and new screw connections to provide additional holding strength.

Both MDF and particleboard have limited tensile and compressive strength, which means that screw connections tend to loosen more easily under frequent load, especially with changing or dynamic forces.
Additionally, MDF tends to swell when exposed to moisture, which further weakens the thread grip.

I would like to organize my explanation a bit:
1. Material: Malm furniture often uses particleboard or MDF panels. These are not very durable for screw connections.
2. Connection type: The screws are usually inserted into inserts or dowels, which can loosen easily.
3. Assembly: Frequent loosening or over-tightening of screws leads to stripping.
4. Load: Moving parts or frequent stress worsen the connection.
Tips:
- Tighten screws gently and avoid over-tightening.
- If holes are stripped, wooden dowel inserts or repair resin can help.
- Threadlocker can provide additional stability, but use it carefully.
By keeping these points in mind, many problems can be avoided.
