The Mounting Magnet with Through Hole Mount contains a ferrite or NdFeB ring magnet within a steel casing. The steel casing is plated to give high corrosion resistance. The steel casing has a hole in it to allow the Pot Magnet with Through Hole Mounting to be easily fixed into position with a cap screw or a bolt into the boss. The design is extremely robust. Powerful Neodymium Screw Borehole Magnet Pot D32mm
Pot Magnet with Through Hole Mounting is available in sizes from 8mm to 150mm diameter with pull forces ranging from 0.5kg up to 500kg. The holes could take M3,M4 M5, M6, M8 and M10 threads. The inner diameter of the ring magnet is much larger than the hole in the steel casing allowing the head of the bolt or screw to easily fit in place.
Neodymium pot magnets are made of a powerful Neodymium magnet borehole in to a steel shell meaning that the north pole is on the centre of the magnetic face and the south pole is on the outer edge around it. The steel pot increases the adhesive force of the magnets giving them an incredible hold for their size. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. These magnets are countersunk on the magnetic face and can be fixed to a surface with a 5mm screw, pot magnets are also available with boreholes and threaded studs.
