Block magnets (87)
Neodymium block magnets combine high adhesive force with a compact, rectangular shape. The flat contact surface makes them useful for recessed mounting in slots and against flat surfaces. Here, you will find versions ranging from a few millimeters for model making and electronics to large blocks for industrial use.
Which block magnet is right for your job?
- Small fasteners and model making: small, lightweight block magnets with an adhesive force of up to a few kilograms.
- Cabinet doors, furniture and interior construction, camper and caravan: flat, larger blocks with approx. 4 to 10 kg adhesive force.
- Workshop and assembly: powerful blocks for tools, molds, and heavier panels.
- Industry and mechanical engineering: very powerful block magnets, also available with a stainless steel handle.
- Screw-on mounting: versions with one or two countersunk holes, sometimes plastic-coated. Pay attention to the pole orientation on the countersunk side.
- Bonding without drilling: self-adhesive block magnets for light-duty applications.
- Humid environments or steel doors: epoxy-coated versions. Read more about steel doors.

Good to know
The stated adhesive force is measured under ideal conditions on a flat steel plate; in practice, the actual adhesive force is lower. Read how adhesive force is determined or see the difference between adhesive force, tensile force, and working load.

Frequently asked questions
Why are there block magnets with a countersunk hole in both a north and south pole version?
For a magnet with a countersunk hole, it is fixed which pole is on the countersunk side. If you want to have two magnets close against each other, for example in a door and a frame, you need one north pole version and one south pole version. Two identical versions will repel each other.
Can I saw or drill through a block magnet?
No. Neodymium is hard and brittle, and can break or splinter during processing; furthermore, the grinding dust is flammable. Therefore, choose a size that fits, or a version with a countersunk hole. More tips in How do you mount a magnet?
