A magnet with a built-in screw is great for screwing with a nut to housings, profiles, and flat bars. Just pass the thread through the hole in the element and tighten the nut on the other side. They are commonly used in machine building, exhibition stands, lighting, and advertising.
The screw is solidly seated in the cup, however, moderation must be maintained when tightening the nut. When assembling, use a torque wrench or tighten with feeling. 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. Avoid mounting directly on hot engine or machine components.
Holders are equipped with standard metric threads (e.g., M4, M6, M8, M10). Stud length varies depending on the model (usually from 8 to 15 mm). 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. However, such a system works point-wise and requires direct contact with metal.

Pros as well as cons of Nd2Fe14B magnets.

Pros

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose strength, even during approximately 10 years – the drop in power is only ~1% (theoretically),
  • They have excellent resistance to weakening of magnetic properties due to external fields,
  • A magnet with a metallic silver surface has an effective appearance,
  • They are known for high magnetic induction at the operating surface, which affects their effectiveness,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to modularity in designing and the ability to customize to client solutions,
  • Significant place in innovative solutions – they are used in hard drives, electromotive mechanisms, precision medical tools, as well as multitasking production systems.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
  • When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
  • We recommend a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
  • Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, small elements of these products can complicate diagnosis medical after entering the body.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what it depends on?

The declared magnet strength represents the limit force, obtained under laboratory conditions, meaning:
  • on a plate made of structural steel, perfectly concentrating the magnetic field
  • with a thickness minimum 10 mm
  • with a surface perfectly flat
  • with zero gap (without paint)
  • for force applied at a right angle (pull-off, not shear)
  • at room temperature

Practical lifting capacity: influencing factors

Real force is affected by specific conditions, such as (from priority):
  • Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Plate thickness – too thin plate causes magnetic saturation, causing part of the power to be wasted to the other side.
  • Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
  • Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal environment – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.

Safety rules for work with neodymium magnets
Flammability

Powder produced during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Demagnetization risk

Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and strength.

Medical implants

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Serious injuries

Large magnets can smash fingers instantly. Never place your hand between two attracting surfaces.

Phone sensors

GPS units and mobile phones are extremely sensitive to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.

Threat to electronics

Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.

Beware of splinters

Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.

Swallowing risk

These products are not toys. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.

Warning for allergy sufferers

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.

Respect the power

Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
