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.

Q4: Is it OK to print my logo on magnet product or package?
A: Yes. Please inform us formally before the production and confirm the design firstly based on our sample.
Q5: How are Neodymium Magnets made?
A: The main ingredients are Neodymium, Iron and Boron. The exact ingredients depend on the grade being produced. We also add a key ingredient called dysprosium to raise the coercivity of the material and increase the resistance to demagnetisation and corrosion. You can read more about the manufacturing process in our company website, www.hawellmagnetics.com.
Q6: How do you make our business long-term and good relationship?
A: We keep good quality and competitive price to ensure our customers' benefits. We respect every customer as our friend and we sincerely do business and make friends with them, no matter where they come from.
