Excellent Quality - Strong neodymium countersunk hole magnets are axial magnetization, is three-layer plating process, which can strengthen the anti-rust and anti-corrosion, enhance the strength of the magnet.
Easy To Use - Rare earth round magnets with countersunk can directly absorbed on magnetic material and can be fixed on non-magnetic material with screws. Sturdy and reliable. When you separate the magnets, be careful and slide gently.
Multipurpose Magnets
N52 neodymium disc magnets with screw hole can be applied to tool storage, photos display, refrigerator magnets.They can also be used for scientific experiments, locker suction or whiteboard magnet.
