Hello everyone,
I am currently dealing with a recurring issue that I often encounter when assembling furniture and other structures: Why do some Malm screws (these typical furniture screws commonly found with Ikea and similar brands) always come loose, even when I tighten them with the correct torque?
I understand that factors such as material properties, installation conditions, and screw type are relevant, but it seems that the connection holds less firmly with some Malm screws than with others, even though they are used in the same way.
Could it be due to the thread depth, the material of the furniture piece, or incorrect assembly?
I would appreciate any tips, especially if you know the physical or mechanical reasons why these screws often don’t stay tight.

Does anyone have specific values for pilot drilling with Malm screws?For Malm screws, a pilot hole of about 70-80% of the screw diameter is often recommended. For example, if the standard Malm screw diameter is 6 mm, a drill bit of approximately 4.5 to 5 mm (0.18 to 0.20 inches) is a good guideline for chipboard, to leave enough material for the threads to grip in the walls.
For solid wood, the pilot hole can be slightly larger to prevent the wood from splitting, especially with harder types of wood.

Are there any special tools or torque settings that are recommended?For cordless screwdrivers, screwdriver bits with torque control or, if possible, a torque wrench are recommended. Screws driven with too much torque can damage the threads in the wood, reducing holding strength and increasing the risk of loosening.
