• About this item

• VERY DURABLENeodymium disc countersunk hole magnets are coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish which greatly increase the longevity of countersunk magnets.
• EASY TO USERound rare earth magnets can directly absorbed on magnetic material and can be fixed on non-magnetic material with screws. Neodymium magnets with holes are sturdy and reliable. When you separate the countersunk hole magnets, be careful and slide gently.
• MAGNETS DIMENSIONS Countersunk hole magnets are 0.47 inches diameter x 0.12 inches thick with a 0.16 inches diameter countersunk hole, which allows them to be fixed to non-magnetic surfaces with a screw.Please note that the main picture is for display only, the actual size is subject to the attached picture.The application of strong magnet with hole are greatly expanded. Tolerances: ±0.2mm(±0.008 inch).
• WIDE APPLICATIONStrong neodymium disc magnets with hole can be applied to tool storage, photos display, refrigerator magnets. They can also be used for scientific experiments, locker suction or whiteboard magnet.
• PROFESSIONAL SERVICEWe are a magnet supplier with professional strength. You can certainly find magnets you want in my shop! If you need mass customization of magnets, contact us and we can meet your needs.
