NdFeB countersunk magnets are specialized neodymium magnets designed with a central countersunk hole, allowing them to be easily mounted with screws or bolts. Their high magnetic strength and convenient mounting make them suitable for a variety of industrial, commercial, and DIY applications.

Standard Disc Countersunk Magnets

The most common type is the standard disc countersunk magnet. These are circular magnets with a single countersunk hole in the center. They are widely used for general mounting applications such as fixtures, signage, and holding tools in place. Their simple design allows easy attachment to flat surfaces while maintaining strong magnetic performance.

Ring Countersunk Magnets

Ring-shaped countersunk magnets are similar to standard disc magnets but have a hollow center in addition to the countersunk hole. This design is often used in mechanical assemblies, rotary devices, or applications where weight reduction is important. Ring countersunk magnets provide a larger surface area for magnetic attraction while allowing secure fastening.

Coated and Specialty Countersunk Magnets

NdFeB countersunk magnets are available with various protective coatings, such as nickel, zinc, or epoxy. These coatings improve corrosion resistance and durability, particularly in humid or outdoor environments. Specialty countersunk magnets may also feature custom dimensions or higher temperature resistance for industrial or automotive applications.

Application-Specific Variations

Some countersunk magnets are designed with specific shapes or tolerances for use in electronic housings, cabinet closures, or machinery. These variations help integrate the magnet seamlessly into the intended assembly while ensuring secure attachment and optimal magnetic performance.

These are ring neodymium magnets with holes used in various applications where they can be stuck and repositioned with ease during use. Neodymium ring magnets are one of the strongest permanent magnetic materials available and have high resistance to demagnetization. They are ideal for applications such as jewelry, watch bands, security systems, calculators, and games.
