What does FZB mean?
FZB is electro-galvanization of the screws (electro-galvanizing), which extends the durability of the screws and makes them more resistant to rust. But electrogalvanizing does not make them acid-free, which is why screws are not suitable for outdoor use (which is designated as an A2 screw type).
Particleboard screws are good for all types of wood and they are self-tapping.
< p>These screws are made for torx screwdrivers (T20).Important info about screws and magnets:
Always choose the right size screw (this is M4). Remember to take into account both the height of the magnet and the thickness of the part you have to screw the magnet onto, so you don't end up screwing through or having a screw that is too small. And also remember to screw the screw head down so that it is level with the magnet - if the screw head sticks out more than the magnet, you create distance and make the magnetic field less strong.
NB! This is one of our smallest screws, but if it's too long, you can easily cut off a bit of the tip.
