Product Features
⭐ Countersunk Hole Design for Flush Mounting
The powerful cup mounting magnet features a precision countersunk hole design in the center, allowing for installation with standard countersunk screws. After installation, the screw head is flush with the magnet surface, ensuring full contact with the mating surface for a clean and professional appearance.
⭐ Durable Nickel Plated Surface
The durable countersunk neodymium magnet surface undergoes a multi layer nickel plating process (Ni-Cu-Ni), providing excellent corrosion resistance and a smooth, glossy finish. This plating enhances durability while maintaining an attractive appearance, making it particularly suitable for visible installation environments.
⭐ Strong Mechanical Fixing
Compared to adhesive only mounting, mechanical screw fixing offers greater security and stability. Even in applications involving vibration or repeated use, this design minimizes displacement or detachment.
⭐ Available in multiple magnetic strength levels
This nickel coated countersunk hole magnet is available in multiple magnetic strength levels, allowing for customization to meet different application requirements. Customers can choose the appropriate level based on the required pulling force, operating conditions, and safety margin.
