There are many types of strong magnets with mounting holes, the more common ones are rectangular strong magnets with mounting holes, round strong magnets with mounting holes and the square strong magnets with mounting holes that we mentioned today.
Square Powerful Magnet with Mounting Holes is briefly described;
Square powerful magnets with mounting holes generally refer to one or more holes machined into high-performance square rare-earth neodymium-iron-boron magnets for fixed mounting.
Sample picture of a typical square power magnet with mounting holes

The hole of square mounting hole magnet is usually in the center, but there are some customers who have special requirements and will ask for the hole to be positioned to the left or right, which is what we often call eccentric hole, which is also no problem. There are also customers will need to drill 2 mounting holes in the square magnet, some thicker square magnet mounting holes may also be designed on the side to meet the special installation.
Mounting holes are mostly in the form of countersunk or through holes. The countersunk hole design allows the screws to be flush with the surface of the magnet without affecting the close contact between the magnet and the adsorbed surface, making it more beautiful and safer to use. The hole diameter and position can be customized according to customer requirements to suit different installation environments.
In terms of application, the square powerful magnets with mounting holes can be easily fixed to various metallic or non-metallic surfaces by screws, bolts and other fasteners for reliable adsorption and positioning.
When choosing square magnets with mounting holes, you need to pay attention to several key indicators: first, the size and thickness of the magnet, affecting the size of the suction; second, the size of the hole and countersunk angle, which is related to the degree of matching of the installation; third, the surface treatment process, which determines the durability; and fourth, the use of ambient temperature, because neodymium-iron-boron magnets at high temperatures will decline in the magnetic properties of high-temperature, such as high-temperature demand, you can choose high-temperature-resistant grades.
