What do you use this magnet for?

Powerful: suitable for workshop and assembly, molds and fixtures, plates and heavier objects. The steel pot concentrates the magnetic force on the flat front, giving a pot magnet on steel much more holding force than the same magnet without a pot. With the internal thread (threaded insert), you screw the magnet onto a bolt or threaded stud, for example in a construction, display or piece of furniture. Which pot magnet do you choose?

The holding force is measured under ideal conditions on a flat steel plate; in practice, the actual holding force is lower. Read how holding force is determined.

Frequently asked questions

How much does this pot magnet hold in practice?

Approx. 18 kg, pulled perpendicularly from thick, flat steel with direct contact with the flat front. On thin sheet steel, through paint or with an air gap, the holding force is considerably lower, and sideways it holds only a fraction of that.

Which bolt fits in the threaded insert?

An M4 bolt or threaded stud. If you need M5, choose the pot magnet Ø25 x 7 mm with M5 threaded insert.

Does it work on stainless steel or aluminum?

A magnet only adheres to magnetic steel. Aluminum and many types of stainless steel are not or barely magnetic. In that case, use a steel counterplate.

Can I use it outside, or without scratching paint?

The NiCuNi coating is intended for dry indoor use. For outdoor or on painted surfaces, pot magnets with rubber coating are more suitable.

We are looking for a permanent supplier for this pot magnet. Is that possible?

Yes. With an annual volume, we reserve stock for you, and you order on account with a purchase order. For larger one-off orders, volume discounts automatically apply. Business ordering.

Safe use

Magnets are not toys and should be kept out of reach of children. Keep strong magnets away from pacemakers, electronics and bank cards. Powerful magnets can snap hard against each other or against metal; keep your fingers away.
