Neodymium Countersunk Pot Magnet – 16mm x 5mm

The Neodymium Countersunk Pot Magnet – 16mm x 5mm is a compact and powerful rare earth mounting magnet designed for secure mechanical fixing to walls, panels, fixtures, equipment and other suitable surfaces. Measuring 16mm in diameter and 5mm thick, this low-profile pot magnet combines strong neodymium magnetic performance with a durable steel housing and a countersunk centre hole for screw mounting.

The countersunk hole allows a compatible countersunk screw to sit neatly within the magnet, creating a clean and secure installation. Once mounted, the magnetic face can attract suitable ferromagnetic steel surfaces, components or strike plates, making this magnet ideal for holding, mounting, positioning and closure applications.

Unlike a standard exposed neodymium disc magnet, the steel pot housing helps concentrate the magnetic field towards the working face while providing additional mechanical protection around the brittle rare earth magnetic material.

Countersunk Hole for Secure Screw Mounting

The integrated countersunk hole allows this pot magnet to be securely attached using a compatible countersunk screw.

This provides a strong mechanical mounting method and allows the screw head to sit neatly within the recessed hole. The low-profile installation is particularly useful where clearance is limited or where a clean finished appearance is important.

Countersunk pot magnets are a practical alternative to adhesive-backed magnets when a more permanent mechanical attachment is preferred.

When installing, select a screw that correctly matches the countersunk hole and mounting substrate. Avoid overtightening, as excessive pressure may damage the magnet or distort the surrounding housing.

Why Choose a Neodymium Pot Magnet?

Neodymium rare earth magnets provide exceptional magnetic strength relative to their size. When incorporated into a steel pot housing, the magnetic circuit is designed to concentrate magnetic flux towards the exposed working face.

This makes pot magnets particularly effective for direct-contact holding against suitable steel surfaces.

The compact 16mm x 5mm dimensions make this model ideal for smaller assemblies where installation space is limited but reliable magnetic holding is still required.

Magnetic Holding and Closure Applications

The 16mm x 5mm neodymium countersunk pot magnet is particularly useful for applications where a small magnetic component needs to be mechanically secured in place.

When paired with a suitable steel surface or strike plate, it can create a discreet magnetic catch or removable mounting point for cabinets, access panels, signs, displays and other components.

Multiple pot magnets can also be used across larger fixtures where additional magnetic holding or more evenly distributed attraction is required.

Getting the Best Magnetic Performance

For maximum holding performance, the working face of the magnet should make direct contact with clean, flat and sufficiently thick ferromagnetic steel.

Magnetic holding force can be reduced by:

• Paint and protective coatings
• Air gaps between the magnet and steel
• Thin steel surfaces
• Uneven or curved mating surfaces
• Dirt or surface contamination
• Sideways or shear forces
• Peeling forces

Where a pull-force rating is provided separately, it generally represents controlled direct-pull testing under ideal conditions and should not automatically be treated as the safe working load for every installation.

Please Note

Neodymium pot magnets can produce powerful attraction forces despite their compact size. Keep fingers clear when bringing the magnet close to steel surfaces or other magnets.

Do not overtighten the countersunk fixing screw. Neodymium magnetic material is hard but brittle and may crack or fracture if subjected to excessive mechanical pressure.

Always ensure the magnet, screw and mounting substrate are suitable for the intended application.

This product should not be used as a certified lifting, safety-critical or overhead load-support device unless the complete installation has been appropriately engineered and tested.

Keep neodymium magnets away from children, pacemakers, medical implants, magnetic storage media and sensitive electronic equipment.
