These are the largest of our Neodymium counter-bored pot magnet range. Neodymium pot magnets are made of a powerful Neodymium magnet sunken 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 counter-bored on the magnetic face and can be fixed to a surface with an 8mm (0.31 in.) screw, pot magnets are also available with countersinks and threaded studs. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully.

This product is often utilised in applications where you require an instant fixing. It can be attached and removed without the need for additional equipment, greatly decreasing downtime and labour. One example where our Neodymium pot magnets are handy is in steel containers, where magnets can be used to hold light fixtures, display signage and create storage space. Visit our brochure here.
