Neodymium Internal Female Thread Pot Magnet – 48mm Diameter x 10mm | M8

The Neodymium Internal Female Thread Pot Magnet – 48mm Diameter x 10mm | M8 is a compact, low-profile rare earth mounting magnet designed for strong, removable attachment to compatible ferromagnetic steel surfaces. Measuring 48mm in diameter x 10mm high, this pot magnet combines high-performance Neodymium Iron Boron (NdFeB) magnetic material with a steel pot housing and an integrated M8 internal female thread.

The M8 female threaded connection provides a practical mounting point for compatible bolts, threaded studs, hooks, eyelets, handles, brackets and custom components. This allows the magnetic base to be incorporated into a wide range of industrial fixtures, machinery, signage, equipment and OEM assemblies without permanently drilling or welding into the supporting steel surface.

Its relatively broad 48mm diameter combined with a slim 10mm profile makes this neodymium pot magnet particularly useful where a substantial magnetic contact area is required while keeping the overall installation compact.

M8 Internal Female Thread

The integrated M8 internal thread allows compatible externally threaded components to be attached directly to the magnetic base.

Depending on the application, compatible components may include:

• M8 threaded studs
• M8 bolts
• Threaded hooks
• Eyelets
• Handles
• Brackets
• Equipment fixtures
• Custom threaded components

The female thread provides a versatile mechanical interface while the magnetic base provides removable attachment to a suitable steel surface.

The specific thread depth has not been supplied, so the length of any mating threaded component should be checked before installation. Avoid bottoming out an excessively long threaded component or overtightening the connection.

Low-Profile 48mm x 10mm Design

At 48mm in diameter and only 10mm high, this pot magnet provides a relatively broad magnetic footprint within a compact vertical profile.

This format can be advantageous for installations where available height is limited, including:

• Compact machinery
• Equipment housings
• Low-clearance fixtures
• Displays
• Removable panels
• Custom product assemblies
• Industrial mounting systems

The low-profile construction allows the magnet to sit close to the supporting steel surface while providing an M8 connection for the attached component.

How Does a Neodymium Pot Magnet Work?

A pot magnet combines a powerful permanent magnet with a steel housing or cup.

The steel pot helps redirect and concentrate magnetic flux towards the exposed working face of the assembly. It also provides mechanical protection around the neodymium magnetic material.

This design makes pot magnets particularly useful where magnetic attraction is primarily required from one working face.

The M8 internal female thread provides the mechanical connection for the component being mounted, while the active magnetic face attaches to compatible ferromagnetic steel.

Neodymium Rare Earth Magnetic Performance

This pot magnet incorporates Neodymium Iron Boron (NdFeB), a high-performance rare earth permanent magnetic material known for producing strong magnetic fields relative to its size.

As a permanent magnet, it requires:

• No batteries
• No electrical wiring
• No charging
• No external power supply

For strongest practical holding performance, the active face should make close, flat contact with clean and sufficiently thick ferromagnetic steel.

Removable Mounting Without Drilling or Welding

The magnetic base can provide a convenient alternative to permanently fixing equipment directly to a compatible steel structure.

This allows attached components to be:

• Installed
• Removed
• Repositioned
• Adjusted
• Relocated

without drilling or welding into the supporting steel surface.

This flexibility can be particularly useful for temporary equipment, production fixtures, sensors, signage and machinery accessories that may need to be repositioned over time.

Magnetic Holding Performance

The practical holding capacity of a pot magnet depends on the complete installation.

Factors affecting performance include:

• Steel thickness
• Steel composition
• Surface flatness
• Contact area
• Paint and protective coatings
• Rust or contamination
• Air gaps
• Direction of applied force
• Weight of attached equipment
• Leverage
• Vibration
• Shock and movement

No specific pull force or Gauss rating has been supplied for this product. Maximum holding capacity should therefore not be inferred from the magnet's 48mm diameter or neodymium construction alone.

Direct Pull vs Shear Loads

Magnetic holding is typically strongest when the force acts perpendicular to the magnetic working face, commonly referred to as direct pull.

If the pot magnet is attached to a vertical steel surface and the mounted component applies a downward force, the assembly is subjected to shear or sliding forces.

Practical holding performance under shear can be considerably lower than direct-pull performance.

Components extending away from the M8 thread can also create leverage or torque on the magnetic base. This should be considered when designing brackets, handles and other mounted equipment.

Compatible Mounting Surfaces

This neodymium pot magnet is designed to attract suitable ferromagnetic iron and steel surfaces.

Compatible materials can include:

• Mild steel
• Iron
• Magnetic steel structures
• Suitable machinery frames
• Ferromagnetic equipment housings

Materials such as aluminium, copper, brass, timber and plastic are not magnetically attracted. Many grades of stainless steel also provide little or no magnetic attraction.

Always verify the magnetic compatibility of the intended mounting surface.

Industrial and Equipment Applications

The combination of a 48mm magnetic base, 10mm low profile and M8 female thread makes this pot magnet suitable for a wide range of professional applications.

Potential users include:

• Manufacturers
• Mechanical engineers
• Equipment builders
• Fabricators
• Maintenance teams
• Automation specialists
• Signage installers
• Workshop operators
• OEM manufacturers

It can be particularly useful where a threaded attachment point needs to be added to existing steel equipment without permanently modifying the supporting surface.

Installation Considerations

Before installation:

• Confirm the target surface is ferromagnetic
• Clean the magnetic face and mating steel surface
• Maximise flat surface contact
• Use a compatible M8 threaded component
• Confirm suitable thread engagement
• Avoid bottoming out the threaded component
• Do not overtighten the connection
• Consider load direction and leverage
• Account for vibration, shock and movement
• Periodically inspect the complete installation

Where accidental detachment could cause injury, equipment damage or another hazard, suitable secondary mechanical retention should be considered.

Please Note

This pot magnet measures 48mm in diameter x 10mm high and features an M8 internal female thread.

No specific thread depth, magnetic grade, coating, pull force, Gauss rating, dimensional tolerance or maximum operating temperature has been supplied and these specifications should not be assumed.

Actual magnetic holding performance depends on the target steel, steel thickness, surface condition, contact area, air gaps, mounting orientation, leverage and dynamic forces.

Neodymium magnetic material is inherently hard and brittle. Avoid uncontrolled impacts and do not drill, cut or machine the magnetic material.

Do not use this pot magnet for lifting people, hazardous overhead suspension or safety-critical load retention unless the complete system has been appropriately engineered, tested and rated.

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