Neodymium Ring Magnet Ø20 x Ø9.8 x 5.1 mm N35 Epoxy with Counterbore South Pole

with drill/countersink hole (south pole)

Neodymium ring magnet 20 x 9.8 x 5.1 mm – epoxy coated with countersink hole (south pole)

This neodymium ring magnet with a countersunk hole has a diameter of 20 mm, an inner diameter of 9.8 mm, and a thickness of 5.1 mm. A countersunk hole is located in the center, making it easy to mount with a screw. The south pole is on the countersunk side, which is important for targeted applications.

The magnet is made of powerful neodymium (the strongest permanent magnetic material) and features a durable epoxy coating (Ni-Cu-Ni-EP). This black protective layer offers excellent resistance to corrosion, moisture, and wear , making the magnet particularly suitable for applications in humid or harsh environments.

Thanks to the galvanized hole, this ring magnet is perfect for permanent mounting on wood, metal, or plastic surfaces without protruding. It's widely used in furniture, displays, mechanical engineering, or as a concealed mounting system.
