These neodymium pot magnets have a metric internal thread and can be screwed together with objects having a suitable external thread. The 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, however, may lead to the formation of rust. Our ferrite pot magnets, on the other hand, are rust-proof.
Please note: This pot magnet has a full-length thread, requiring extra care when threading screws, hooks and the like to prevent damage to the rubber coating.
