What do you use this magnet for?

Suitable for hanging light objects, displays, lighting, signs, and mounting in workshops and interior construction. The steel pot concentrates the magnetic force on the flat front surface, 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 structure, display, or piece of furniture. Which pot magnet should 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. 8 kg, pulled perpendicularly from thick, flat steel when in direct contact with the flat front surface. 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. Tighten it by hand or slightly, so as not to damage the threaded insert.

Can I hang a sign or lamp with it?

Light signs, displays, and lamps, yes, on a flat steel surface. If it hangs on a vertical wall, only count on a fraction of the holding force, and do not hang anything heavy above people's heads without additional safety.

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 backing plate.

We build lighting or displays in series. Can you supply that?

Yes. For a series, we provide a quote, and for an annual volume, we reserve stock so you do not have to wait. You order on account with a purchase order. 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.
