This is a block neodymium magnet with a M3 countersunk holes. The hole dimensions of countersunk neodymium magnets are determined by the large hole diameter, the small hole diameter, and the angle, which is typically 90 degrees to ensure precise installation and compatibility. Almost all countersunk neodymium magnets are magnetized through the direction of the hole. Countersunk neodymium magnets are widely used in various fields, such as mounting and fixing, magnetic assemblies (especially with bolts, screws, and fasteners), ensuring reliable and stable performance.
Here is an example drawing for your reference. Need countersunk magnets, please share us the L*W*H and the screw hole sizes. We support screw hole sizes such as M3, M4, M5, M6, M8, and M10.
