66mm Diameter Black Rubber Coated Neodymium Magnets with M6 Internal Thread, holds approx. 17kg

This neodymium magnet system has a metric internal thread and can be screwed together with objects having a suitable external thread. The black rubber coating protects delicate surfaces from scratches and, at the same time, increases the load capacity in shear direction. The rubber protects the magnet from occasional moisture and splashes. Permanent outdoor use, però, may lead to the formation of rust.
