Flat countersunk neodymium disc and block magnets with one or two boreholes can be fastened with a countersunk head screw. They are only 3 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 neodymium disc countersunk 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.
Countersunk magnets are available with either pole on the magnetic face so that they can be used as a pair to attract or repel. If you are using two magnets to attract you need to make sure the opposite poles are facing each other as identical poles will repel! Some of their uses include:
Cabinet making – Typically you’ll find countersunk magnets used as invisible closing mechanisms and soft drawer closures.
DIY – Neodymium magnets can be used to create gate latches, holding doors open and closed, fixing bath panels and creating removable access panels.
Shop fitting – Magnets are often used in shelving and lighting systems, screens, window displays and signage.
Regular countersunk magnets are the only suitable choice if you need magnets to work through a gap, while countersunk pot magnets work best when clamped directly against a steel surface.
