A range of small 12mm (0.47") diameter neodymium and ceramic disc magnets. Circular disc magnets can be fixed in place using adhesive or can be pushed into circular drilled holes in wood or plastic. Our 12mm (0.47") diameter disc range includes our strong neodymium countersunk magnets which can be fixed in place using a bolt or screw and are available with either pole on the countersunk face so that two magnets can be used together.
