Custom Square NdFeB Magnets with Countersunk Holes
Engineered Magnetic Components for Compact Mechanical Assemblies
Solid Neodymium | Custom Hole Geometry | Drawing-Based Manufacturing
Magnetic Components Designed Around Your Assembly
When installation space is limited, a countersunk neodymium magnet provides a practical way to integrate permanent magnetic force directly into a mechanical structure.
Unlike conventional block magnets, this design features a countersunk mounting hole machined directly into the solid NdFeB body. A compatible flat-head screw can secure the magnet to its mounting position while keeping the assembly compact.
We manufacture square and rectangular countersunk magnets according to customer drawings, including customized block dimensions, hole positions, countersink geometry and magnetic specifications.
Design Details That Matter in Assembly
Integrated Countersunk Geometry
The recessed screw seat accommodates a compatible flat-head fastener, helping achieve a compact mounting arrangement.
Customized Hole Position
Hole diameter, countersink angle, depth and center position can be reviewed according to the mounting drawing.
Solid NdFeB Construction
The magnet body itself provides the magnetic function without an additional steel cup or external magnetic housing.
Application-Specific Dimensions
Length, width, thickness and edge details can be customized to match the available installation space.
From Technical Drawing to Finished Magnet
For custom countersunk magnets, the mounting geometry and magnetic specifications need to be considered together.
Our production evaluation focuses on:
Block dimensions and dimensional tolerances.
Countersunk hole diameter, angle and depth.
Remaining material thickness around the hole.
Magnetization direction and required magnetic grade.
Coating thickness and assembly clearance.
Drawings and samples can be used as references for manufacturing feasibility assessment before order confirmation.
