Ø30x10/5.5x10 mm Countersunk Neodymium Magnet – NiCuNi Coated, High Strength Mountable Magnet

The Ø30x10/5.5x10 mm countersunk neodymium magnet is a high-strength N35-grade rare-earth magnet designed for screw-mountable applications. Featuring a 5.5 mm center hole and 10 mm countersink diameter, it is ideal for securely attaching to non-magnetic surfaces like wood, plastic, or composites using standard screws.

This magnet is coated with a triple-layer NiCuNi plating (Nickel + Copper + Nickel) for enhanced resistance against corrosion, oxidation, and wear—making it suitable for both industrial and decorative applications.

Common uses include magnetic mounting systems, furniture hardware, sensor holders, and mechanical positioning units where high magnetic force and reliable fixation are required.
