A magnet with a built-in screw is great for screwing with a nut to housings, profiles, and flat bars. Mounting consists of inserting the screw into the hole and securing with a nut (e.g., wing nut). They are commonly used in machine building, exhibition stands, lighting, and advertising.
The threaded stud is an integral part of the steel housing, but avoid overtightening the thread. We recommend using spring washers to avoid the need for forceful tightening. The construction is durable and adapted to industrial conditions.
Standard neodymium holders are adapted to work in temperatures up to 80°C. We also offer holders made of ferrite magnets (resistant up to 200°C) or special high-temperature versions. Remember that even momentary overheating can weaken the holder.
We use standardized threads that fit typical nuts available in every store. Ensure thread length is sufficient to pass through the hole in your material and tighten the nut. The thread is made of galvanized steel, ensuring corrosion resistance.
Yes, the steel housing (cup) focuses the magnetic field, significantly increasing attraction force on the active side. This force drops very quickly with increasing distance (air gap).

Advantages as well as disadvantages of rare earth magnets.

Pros

Apart from their strong holding force, neodymium magnets have these key benefits:
  • They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
  • They do not lose their magnetic properties even under strong external field,
  • A magnet with a metallic gold surface has better aesthetics,
  • Magnetic induction on the working part of the magnet remains strong,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Thanks to the possibility of accurate shaping and customization to custom solutions, NdFeB magnets can be modeled in a broad palette of shapes and sizes, which expands the range of possible applications,
  • Key role in modern industrial fields – they find application in HDD drives, drive modules, diagnostic systems, as well as multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in compact constructions

Disadvantages

Disadvantages of neodymium magnets:
  • At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited ability of creating nuts in the magnet and complex forms - preferred is cover - magnet mounting.
  • Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these magnets can complicate diagnosis medical when they are in the body.
  • Due to expensive raw materials, their price is higher than average,

Pull force analysis

Maximum magnetic pulling force – what it depends on?

The lifting capacity listed is a measurement result executed under the following configuration:
  • on a plate made of mild steel, optimally conducting the magnetic flux
  • whose transverse dimension is min. 10 mm
  • with an ideally smooth touching surface
  • without any clearance between the magnet and steel
  • during detachment in a direction vertical to the plane
  • at room temperature

Lifting capacity in real conditions – factors

In practice, the real power results from several key aspects, presented from most significant:
  • Gap (betwixt the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
  • Direction of force – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
  • Base massiveness – too thin steel causes magnetic saturation, causing part of the flux to be escaped to the other side.
  • Steel grade – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
  • Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
  • Thermal environment – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.

Lifting capacity was measured by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.

Precautions when working with NdFeB magnets
Electronic devices

Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Do not give to children

Absolutely keep magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are fatal.

Conscious usage

Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Precision electronics

A strong magnetic field interferes with the functioning of compasses in phones and GPS navigation. Keep magnets close to a smartphone to avoid damaging the sensors.

Risk of cracking

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Health Danger

Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Bone fractures

Big blocks can crush fingers instantly. Under no circumstances place your hand betwixt two strong magnets.

Fire warning

Powder created during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Nickel allergy

It is widely known that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for encased magnets.

Power loss in heat

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
