Product Features
Straight Hole Structure - Compatible with Flathead Screws
The center through hole design allows direct use of standard flathead screws, achieving quick and reliable mechanical fastening. Compared to countersunk magnets that primarily rely on countersunk screws and magnetic positioning, the straight hole structure offers better screw compatibility and is more suitable for applications requiring repeated installation or high installation strength, effectively avoiding the displacement risk caused by relying solely on magnetic positioning.
Steel Shell - Enhances Magnetic Force
NdFeB magnets are embedded within a steel shell, effectively concentrating the magnetic force on the adsorption surface, providing higher effective adsorption force within the same size. Compared to ordinary bare magnets or non steel shell structures, it exhibits higher stability under vertical installation, vibration, or shear forces.
Black Epoxy Coating - High Corrosion Resistance
The surface is coated with black epoxy resin, offering superior corrosion resistance, moisture resistance, and abrasion resistance compared to traditional nickel plating. Compared to nickel plated pot magnets, this epoxy plated pot magnet is more suitable for outdoor, humid, or mildly corrosive environments, significantly reducing the risk of rust and extending service life.
Stable and Reliable Installation
Dual fixing methods of magnetic attraction and screws ensure quick installation and long term stability. Compared to using magnetic attraction alone, this method is safer and more reliable during equipment operation, transportation, or long term use, effectively preventing rare earth mounting magnets from loosening or falling off.
Wide Applications
Black round neodymium cup magnet is widely used in mechanical equipment, tooling fixtures, metal frames, and industrial display systems. It is especially suitable for applications requiring precise screw positioning and long term stable fixation in complex or demanding environments.
