About counterbore (screw hole) magnets, we have also introduced some before. The main material is neodymium iron boron. The commonly used types are round counterbore magnets, square countersunk magnets, triangle counterbore magnets, arc counterbore magnets, and rectangular counterbore magnets. Today, we will talk about its magnetization direction and drawings.
Neodymium counterbore magnet is a powerful magnet with a functional type. One end of the magnet has a standard straight hole on the surface, but the other end has an inclined counterbore on the surface. It is usually measured by outer diameter, through hole diameter, major diameter, depth and angle, and the angle is generally 90 degrees.
Magnetization direction of counterbore magnet;
Basically, all NdFeB counterbore magnets are axially magnetized, except for special cases.
Drawing reference of several commonly used counterbore magnets;
1、Drawing of round counterbore magnet;
2、Drawing of square counter bore strong magnet
3、Drawing of rectangular counterbore neodymium magnet;
4、Drawing of countersunk hole pot magnet;
The above is about the magnetization direction and drawings of the counterbore magnet. This type of magnet can be widely used in home, experiment, mechanical equipment and many other purposes. Customers who need to buy this kind of magnet are welcome to consult the courage magnet manufacturer for quotations.
