Countersunk magnets are indispensable in carpentry, furniture making, and modeling as hidden closures. Thanks to the hole with a chamfer (conical), the screw head hides in the magnet, ensuring a flat contact surface. Model UMS 60x18x8.5x15 / N38 will successfully hold inspection doors, tools in the workshop, or shop display elements.

Remember that neodymium breaks easily if the screw is tightened too hard. Avoid forceful tightening when you feel resistance. The screw head should not protrude above the magnet surface, but it cannot burst it either.

To create a pair (magnet-magnet), you need one holder with an N pole on the chamfer and another with an S pole. If you need a pair, ask about availability of complementary sets or check the description. Mounting a magnet to a plate eliminates the problem of matching poles and is easier.

This force is measured in ideal laboratory conditions when pulling at a 90-degree angle. In practice, when mounted on a wall (shear force), the magnet will hold significantly less (approx. 20-30% of nominal). Paint or veneer on metal also reduces effective attraction force.

The steel housing (cup/pot) acts as a magnetic shield, directing all power to the front of the holder. The housing absorbs impacts, preventing the magnet from crumbling and cracking. A bare ring has a dispersed field on both sides but is weaker in point holding.

Advantages and disadvantages of rare earth magnets.

Benefits

Apart from their notable magnetic energy, neodymium magnets have these key benefits:

They retain full power for almost 10 years – the drop is just ~1% (according to analyses),
They maintain their magnetic properties even under strong external field,
A magnet with a metallic gold surface looks better,
Magnetic induction on the top side of the magnet remains extremely intense,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
Thanks to the possibility of accurate molding and adaptation to unique requirements, magnetic components can be produced in a wide range of forms and dimensions, which makes them more universal,
Key role in future technologies – they serve a role in HDD drives, electric drive systems, medical devices, and industrial machines.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Disadvantages

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited ability of producing nuts in the magnet and complicated forms - recommended is a housing - magnet mounting.
Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets is economically unviable,

Lifting parameters

Maximum holding power of the magnet – what affects it?

Magnet power is the result of a measurement for ideal contact conditions, taking into account:

with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
with a cross-section minimum 10 mm
characterized by smoothness
under conditions of no distance (metal-to-metal)
during detachment in a direction perpendicular to the plane
at ambient temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

In practice, the real power depends on a number of factors, ranked from the most important:

Distance – the presence of any layer (paint, dirt, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
Steel grade – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Temperature – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate decreases the holding force.

Warnings

Precision electronics

A powerful magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.

Magnet fragility

Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.

Metal Allergy

Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness happens, cease handling magnets and wear gloves.

Thermal limits

Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.

Flammability

Powder generated during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Do not underestimate power

Be careful. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can react.

Threat to electronics

Intense magnetic fields can erase data on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.

Health Danger

Warning for patients: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Crushing risk

Danger of trauma: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.

Do not give to children

Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from children and animals.
