Flat countersunk neodymium disc and block magnets with one or two boreholes can be fastened with a countersunk head screw. They are only 4 mm thick and therefore very discreet for hanging up signs, tools, etc. Screw-on magnets are very popular in the areas of kitchen installations, booth and store construction, signage technology, furniture construction, etc.
Don’t forget to buy low-priced metal discs as counterparts in our website.
We also carry round screw-on pot magnets, which look very similar, but have a much higher adhesive force:
Countersunk pot magnets
Pot magnets with cylindrical borehole
Pot magnets with ferrite magnet
Small size ring magnet, axially magnetised like almost all neodymium rings. This one has a 90°-countersunk. Neodymium magnets are made of neodymium, iron and boron and are the strongest raw magnets.
To make friends through business and share success together is our end goal.
