N52 Countersunk Neodymium Block Magnet

Precision-Machined NdFeB Magnets for Secure Screw Mounting

Custom Dimensions | N35–N52 Grades | Multiple Coatings | OEM/ODM

Product Overview

Our N52 countersunk neodymium block magnets are designed for applications requiring strong magnetic attraction and secure mechanical installation. The integrated countersunk hole allows the magnet to be fixed with a compatible flat-head screw, reducing the need for additional mounting structures.

Manufactured from sintered NdFeB material, these square and rectangular neodymium magnets are available in different magnetic grades, dimensions, hole configurations and protective coatings. Custom production is supported based on technical drawings, samples or assembly requirements.

Countersunk Hole Design for Screw Mounting

The countersunk hole is designed to accommodate a compatible flat-head screw, allowing the magnet to be mechanically secured to a mounting surface. This design helps reduce unwanted movement during assembly and repeated use.

• Customized hole diameter and countersink dimensions.

• Compatible with specified flat-head screw sizes.

• Custom block thickness and external dimensions.

• Hole position and edge distance according to drawings.

Note: Screw dimensions, countersink angle and hole depth should be confirmed before production to ensure proper fitting.

Protective Coating Options

Select the surface finish according to humidity, corrosion exposure, appearance and assembly requirements.

Industrial Applications

Custom countersunk neodymium magnets are suitable for assemblies requiring both magnetic attraction and screw-fixed installation.

• Industrial fixtures and positioning systems.

• Machine guards, access panels and equipment enclosures.

• Magnetic clamps and removable mounting assemblies.

• Automation equipment and mechanical components.

• Custom magnetic holders and tool fixtures.

• Furniture fittings and cabinet door assemblies.

Manufacturing & Quality Inspection

Each custom magnet specification is reviewed before production. Inspection requirements can be agreed according to the drawing and purchase order.

• Incoming material and magnetic grade verification.

• Dimension and countersunk hole inspection.

• Coating appearance and surface condition checks.

• Magnetic performance testing according to agreed specifications.

• Final inspection and export packaging.

Material certificates, batch inspection reports and applicable quality-system documentation can be discussed according to project requirements. ISO 9001 or IATF 16949 certification should only be claimed where a valid certificate and applicable production scope are available.
