Magnetic holders with internal thread can be versatile tools, used across industrial as well as household applications, e.g. in automotive. They consist of a neodymium magnet, typically NdFeB, enclosed within a steel shell, covered with zinc to prevent rusting. The female thread, available in sizes from M4 to M8, allows insertion of bolts, which facilitates assembly of various components, like nameplates, tools, or lights. They operate via a powerful magnetic zone, that focuses in the contact area, ensuring load capacity ranging from one to sixty kilograms, depending on mount size. These are particularly helpful in the automotive industry, e.g. for securing body panels, as well as in marketing, for hanging banners. Certain types have a rubber coating, e.g. in black or yellow colors, helping prevent surface damage and improves moisture resistance. Advantages include great strength, simple mounting due to the internal threading, as well as the option to move massive steel components. However, the holding force depends on surface thickness, type of steel, and the gap between holder and object. Preventing mechanical shocks is crucial, since neodymium magnets are fragile, and over-tightening the bolt can cause damage. In addition, a magnetic zone may interfere with electronics, such as smartphones or magnetic cards, therefore mounts should be stored away from those devices. Choosing mounts from trusted suppliers is advised, to ensure high quality and safe use during operation.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their exceptional magnetic power, neodymium magnets offer the following advantages:

They have stable power, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
They show superior resistance to demagnetization from external magnetic fields,
Because of the brilliant layer of silver, the component looks aesthetically refined,
The outer field strength of the magnet shows elevated magnetic properties,
These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to build),
The ability for accurate shaping or adjustment to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
Wide application in modern technologies – they are used in data storage devices, electromechanical systems, diagnostic apparatus and sophisticated instruments,
Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in small dimensions, which makes them useful in compact constructions

Disadvantages of NdFeB magnets:

They are fragile when subjected to a strong impact. If the magnets are exposed to external force, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage , and at the same time enhances its overall resistance,
Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
Magnets exposed to humidity can degrade. Therefore, for outdoor applications, we suggest waterproof types made of coated materials,
Limited ability to create internal holes in the magnet – the use of a magnetic holder is recommended,
Potential hazard due to small fragments may arise, in case of ingestion, which is important in the context of child safety. Moreover, minuscule fragments from these assemblies have the potential to disrupt scanning if inside the body,
In cases of large-volume purchasing, neodymium magnet cost may not be economically viable,

Safety Guidelines with Neodymium Magnets

Neodymium magnets are the most powerful, most remarkable magnets on earth, and the surprising force between them can shock you at first.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets can become demagnetized at high temperatures.

Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Magnets made of neodymium are extremely fragile, leading to their cracking.

Neodymium magnets are characterized by significant fragility. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.

The magnet is coated with nickel - be careful if you have an allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

In the case of placing a finger in the path of a neodymium magnet, in that situation, a cut or even a fracture may occur.

Do not give neodymium magnets to youngest children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Avoid bringing neodymium magnets close to a phone or GPS.

Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Be careful!
