Countersunk Hole for Easy Mounting

The central countersunk hole allows the pot magnet to be securely fixed with a countersunk screw. Different hole sizes can be produced to match different mounting requirements.

Countersunk Neodymium Magnets for Screw Mounting

Our countersunk neodymium magnets are designed for applications that require strong magnetic holding combined with secure screw mounting. Made from high-performance NdFeB rare earth magnet material, these round magnets feature a precision-machined countersunk hole that allows the screw head to sit neatly inside the magnet.

Available with countersunk holes for M3, M4, M5, M6 and M8 screws, they are widely used as magnetic mounting magnets, screw fixing magnets, magnetic fasteners and removable magnetic holders for industrial equipment, furniture, cabinets, displays, signs, fixtures and DIY assemblies.

The standard Ni-Cu-Ni nickel coating provides a smooth metallic surface and helps protect the neodymium magnet during normal use. Other coatings can be supplied according to the working environment and project requirements.

We manufacture round countersunk magnets in N35, N42, N48, N50 and N52 grades, with custom diameter, thickness, countersunk diameter, through-hole size, magnetization direction and coating available for OEM projects.

For volume buyers, we can produce custom countersunk neodymium magnets according to drawings or samples, including special dimensions and hole configurations for different mounting structures.

Custom options:
Diameter • Thickness • M3/M4/M5/M6/M8 Hole • Countersunk Diameter • N35–N52 Grade • Nickel/Epoxy/Zinc Coating • Magnetization Direction • Packaging

Countersunk neodymium magnets can be integrated into products where the magnetic component needs to remain hidden, compact and securely fixed in position. The countersunk hole allows the magnet to become part of the product structure rather than simply being attached to the surface.

In furniture and cabinetry, they are commonly used for cabinet doors, access covers, removable panels, storage systems and concealed magnetic closures. Their compact round design makes them suitable for applications where installation space is limited and a cleaner finished appearance is preferred.

For retail displays and signage, countersunk magnets can be used to hold display panels, signs, product fixtures and interchangeable components. Magnetic attachment makes it easier to change layouts or replace display elements without redesigning the complete mounting structure.

In workshops and industrial equipment, these magnets can be incorporated into inspection covers, positioning fixtures, guards, brackets, tool storage systems and equipment accessories. Different magnet diameters and grades can be selected according to the available installation space and required holding force.

They are also suitable for DIY products, lighting assemblies, exhibition systems, automation equipment and custom magnetic components. For OEM applications, the diameter, thickness, countersunk hole and magnetic grade can be customized to match the final product design.
