Ring neodymium magnets
magnets with countersunk or straight hole
Variants: regular ring (straight) or with countersink (socket).
Mounting: match the hole profile to the fastener; not every ring accommodates a screw head.
Application: cabinet closures, holders, separators, speakers.
Safety: caution required when tightening (brittle material).
Coating: anti-corrosion, standard nickel (Ni-Cu-Ni).
Polarization: standard axial (top/bottom), possibility of pairing.
Direction of magnetization
↑ axial
→ diametral
↗ radial
This makes them ideal elements for creating cabinet locks, tool holders, inspection hatches or door closing systems. They are widely used in carpentry for mounting furniture fronts, where an invisible yet strong connection is required.
Important mounting note: Neodymium is a sintered material, which means it is very hard but at the same time brittle like ceramic. When tightening the magnet, moderation should be exercised – we recommend tightening by hand with feeling. Using an impact driver or tightening the screw too hard will almost certainly cause the magnet to crack. It is also worth using a thin rubber or plastic washer to eliminate stresses.
For applications requiring pairing (e.g., box closures), remember to select attracting magnets (one with the N pole on the chamfer, the other with the S pole). If you plan to use them for speakers or physics experiments (levitation on a tube), check the inner hole dimension carefully to fit your project. Our warehouse offers a wide selection of inner and outer diameters available immediately.

How to use magnets with a hole
The centre hole allows a connection with a part passing through its centre. Check internal diameter, external diameter and height; cylindrical and countersunk holes are not interchangeable. Not every model accommodates a screw head.
Before assembly, account for magnet brittleness and avoid point loads. Check the product parameters and use the magnet calculator (v2 — engineering) for initial sizing. If you need a magnet in a housing for screw mounting, see magnetic holders.
How to select a ring magnet with a hole
Three dimensions and the hole profile
For a ring, you need the outside diameter, bore diameter and height. A cylindrical hole is not the same as a countersunk recess for a screw head. For a countersunk hole, check both diameters and the product drawing. The word “ring” alone does not confirm compatibility with a particular screw.
Magnetisation and the mating component
A hole allows a pin or another component to pass through, but does not define the pole positions. Check the magnetisation direction on the model's page. With a sensor or another magnet, this matters as much as the dimensions. If you do not need a hole, compare solid cylindrical magnets.
Mounting without point loading
Do not tighten a screw directly against the brittle magnet without checking the model's mounting requirements. Point loading can damage the magnet or coating. For a complete screw-mounted assembly, compare magnetic holders in a housing rather than treating a bare ring as a holder.
Calculations and batch selection
The magnet calculator (v2 — engineering) provides a ring field model, not a validated measurement of the assembled joint's pull force. For a B2B enquiry, include the hole drawing, dimensions, quantity and operating conditions. Confirm the final choice with an assembly test.
