Female Thread Neodymium Pot Magnet – 25mm Diameter x 15.8mm | Slim Profile

The Female Thread Neodymium Pot Magnet – 25mm Diameter x 15.8mm | Slim Profile is a compact rare earth mounting magnet designed for removable holding, positioning and fixture applications on compatible ferromagnetic steel surfaces. Measuring 25mm in diameter x 15.8mm overall, this pot magnet combines a powerful Neodymium Iron Boron (NdFeB) permanent magnet with a protective steel pot and an integrated female threaded mounting connection.

The internal female thread allows compatible threaded components such as bolts, studs, hooks, handles or custom fittings to be attached to the magnetic base. Its slim-profile design makes it particularly useful for installations where available space is limited or a compact magnetic mounting solution is preferred.

Suitable for industrial equipment, signage, displays, fixtures, machinery, sensors, lighting, workshop applications and OEM assemblies, this female-thread pot magnet provides a practical way to create removable and repositionable attachment points without permanently drilling or welding into the supporting steel surface.

Female Thread for Versatile Mounting

The integrated female threaded connection provides a convenient interface for attaching compatible externally threaded components to the magnetic base.

Depending on the intended application, these may include:

• Threaded studs
• Bolts
• Hooks
• Eyelets
• Handles
• Brackets
• Custom fixtures
• Equipment components

This allows the magnetic base to be incorporated into a wide variety of removable mounting systems.

A specific thread size and thread depth have not been supplied for this product and should be confirmed before selecting mating hardware.

Slim-Profile Magnetic Mounting

The 25mm diameter x 15.8mm overall design provides a compact mounting footprint for installations where space is restricted.

The slim profile can be particularly useful where a larger or taller magnetic assembly would interfere with surrounding components.

Potential applications include:

• Compact machinery
• Display systems
• Equipment housings
• Tight installation spaces
• Low-profile fixtures
• Custom product assemblies

The suitability of the magnet should be assessed according to the available space, mounting orientation and required holding performance.

Neodymium Rare Earth Magnetic Performance

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

Because neodymium is a permanent magnetic material, no batteries, electrical wiring or external power source are required.

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

How Does a Neodymium Pot Magnet Work?

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

The steel pot helps redirect and concentrate magnetic flux towards the exposed working face while also providing mechanical protection around the brittle neodymium material.

This construction makes pot magnets particularly useful for applications where strong magnetic attraction is required primarily from one face of the assembly.

The female threaded connection then allows another compatible component to be mechanically attached to the magnetic base.

Removable Mounting Without Drilling or Welding

When attached to a suitable steel surface, this pot magnet can create a removable magnetic fixing point without permanently modifying the supporting steel.

This can be advantageous for:

• Temporary installations
• Reconfigurable equipment
• Prototyping
• Machinery modifications
• Displays and signage
• Maintenance equipment
• Frequently repositioned accessories

The magnet can be relocated as requirements change, provided the new mounting surface is suitably ferromagnetic and capable of providing adequate magnetic contact.

Magnetic Holding Performance

Actual magnetic holding performance depends on the complete installation rather than magnet diameter alone.

Important factors include:

• Steel thickness
• Steel composition
• Surface flatness
• Available contact area
• Paint and protective coatings
• Rust or contamination
• Air gaps
• Direction of applied force
• Weight of the attached component
• Leverage
• Vibration and movement

No specific pull-force or Gauss rating has been supplied for this product, so maximum holding capacity should not be inferred from its 25mm diameter or neodymium construction.

Direct Pull vs Shear Loads

Magnetic holding is typically strongest under direct pull, where force is applied perpendicular to the steel surface.

When the magnet is mounted vertically and the attached component applies a downward load, the magnetic assembly experiences shear or sliding forces. Practical holding performance in this orientation can be significantly lower than direct-pull performance.

Long brackets, hooks or other components attached to the female thread can also create leverage that increases the force acting on the magnetic base.

These factors should be considered when designing the complete mounting system.

Industrial and Equipment Applications

Female-thread pot magnets are useful for creating removable attachment points across a range of professional environments.

Potential industries and applications include:

• Manufacturing
• Industrial automation
• Mechanical engineering
• Machinery maintenance
• Retail and exhibition displays
• Signage
• Lighting systems

The internal thread makes it possible to attach application-specific components while retaining the convenience of a removable magnetic base.

Installation Considerations

Before installation:

• Confirm the mounting surface is ferromagnetic
• Keep the magnet and steel surface clean
• Maximise flat contact between the working face and steel
• Confirm the female thread size before selecting hardware
• Ensure adequate thread engagement
• Avoid bottoming out an excessively long threaded component
• Do not overtighten the threaded connection
• Consider load direction and leverage
• Account for vibration or dynamic movement

Where accidental detachment could create a hazard, appropriate secondary mechanical retention should be considered.

Please Note

A specific female thread size, thread depth, magnetic grade, coating, pull force and Gauss rating have not been provided for this product and should not be assumed.

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

Neodymium magnets are powerful but inherently hard and brittle. Avoid uncontrolled impacts and do not drill, cut or machine the magnetic material.

Do not use this 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 magnets away from children, pacemakers, medical implants, magnetic storage media and sensitive electronic equipment.
