Neodymium magnets with a hole and countersink Our countersunk neodymium block magnets are well suited for mechanical attachment with standard countersunk screws. We offer countersunk magnets only in high grades such as N40 and N45, optionally nickel-plated or coated with black epoxy. Magnetic properties of NdFeB N40 neodymium magnets: - Remanence: 1.261.29 T - Coercive force HcB: >900 kA/m - Intrinsic coercive force HcJ: >955 kA/m - Maximum operating temperature: 80C The specified holding force was determined by pulling the magnet vertically from a 20 mm thick, ground-flat St37 steel plate at room temperature. In exceptional cases, the value may deviate by up to -10% from the specified rating. In general, however, this value is exceeded.
