Neodymium Countersunk Hole Magnet

Custom Countersunk Neodymium Magnets Supplier and Manufacturer

The neodymium countersunk hole magnet is one of the more common Neodymium magnets. Countersunk magnets, also known as the round cup, cup, or RB magnets, are powerful mounting magnets built on a steel cup with 90 countersunk holes in the working surface to accommodate a standard one-head screw neodymium magnet. Generally, their magnetic holding force is concentrated on the working surface and is significantly stronger than that of a single magnet. Neodymium countersunk hole magnets are used in any application requiring high magnetic strength. They are widely used in computers, automobiles, electric machinery, electro-sound devices, automatic control, magnetic force mechanism, microwave communication, petrochemical industry, medical apparatus and equipment.
