Neodymium Countersunk Magnet Engineering Data
How to Choose the Right Countersunk Magnet Grade? (Strength vs. Temp)
Grade selection is about finding the right balance between magnetic strength, cost, and heat resistance.
- Neodymium Countersunk Magnet Strength Grades: N55 offers highest force in a compact size. N35 provides the best cost-performance for holding applications.
- Neodymium Countersunk Magnet Heat Grades: Standard 'N' grades demagnetize above 80°C. For fixed tools, processing tools, decorations, door locks, you MUST use high-temp grades (e.g., M, H, SH, UH). Contact our engineers to validate your thermal requirements.
How to Choose the Right Countersunk Magnet Coating
Iron in Neodymium countersunk magnets rusts easily, so a protective coating is essential. Here is a simple guide to help you choose countersunk magnet plating .
Nickel Plated Countersunk Magnets (Ni-Cu-Ni)
Best for: Dry, indoor use in offices, schools, and homes.
Epoxy Coated Countersunk Magnets
Best for: Outdoor, wet, and marine environments.
Gold Plated Countersunk Magnets (Au)
Best for: Medical implants, life-long devices, and high-end scientific equipment.
Rubber Coated Countersunk Magnets
Best for: Outdoor use, vehicle mounts, and protecting delicate surfaces.
Zinc Plated Countersunk Magnets (Zn)
Best for: Automotive use or dry areas with scratch risk.
Black Nickel Plated Countersunk Magnets (Ni-Cu-Black Ni)
Best for: Hidden, or decorative uses requiring a sleek black finish.
PTFE Coated Countersunk Magnets (Teflon)
Best for: Medical labs, chemical plants, and low-friction applications.
Plastic Coated Countersunk Magnets
Best for: Waterproof applications, preventing scratches on delicate surfaces.
Technical Specifications: Magnetization & Tolerances
Neodymium Countersunk Magnet Tolerances:Our standard tolerances are determined by the dimension:
- Dimensions over 10mm: +/- 0.1mm
- Dimensions 10mm and under: +/- 0.02mm
Neodymium Countersunk Magnet Magnetization Directions: 99% are Axially magnetized (through Thickness). The key specification is which pole is on the countersunk face. We offer North-face and South-face countersunk magnets, allowing them to be used in attracting pairs.

What Are Neodymium Countersunk Magnets?
Neodymium Countersunk Magnets are permanent magnets (main body is ring-shaped) with a cone-shaped hole. This hole is perfectly designed for a standard flat-head screw. The primary benefit is that the screw head sits flush with or below the magnet’s surface, providing a clean, professional, and non-snagging finish.
- Provides the most secure and permanent mechanical mounting.
- Allows strong magnets to be fixed to non-magnetic surfaces (wood, plastic, etc.).
- Available in matched North/South pairs for magnet-to-magnet closures.
- The hole slightly reduces pull force but adds immense functionality.
Neodymium Countersunk Magnets Applications
Neodymium countersunk magnets are the ultimate solution for mounting, holding, and fastening. They are essential in industrial jigs and fixtures, where they are bolted in place to hold components. They are also widely used in high-end cabinetry, signage, and retail displays for a secure, hidden, and professional mount. Their robust, flush-mount design makes them a favorite for OEM product integration.
