These versatile, thin countersunk magnets from first4magnets are ideal for creating discreet magnetic cupboard door catches or for holding removable bath panels in place plus many other uses. Although just 3mm thick, each magnet is capable of supporting 4.5kg in a vertical position or 0.9kg in a shear position when in direct contact with another magnet or a steel surface. They are available with either pole on the magnetic face so two of these can be used on opposing surfaces to attract. For the perfect finish, countersink these magnets into a wooden surface and screw in place using a stainless steel screw.
