Which magnetic hook do you choose? By holding force and design
A hook magnet is a neodymium pot magnet with a hook. You attach it to a steel surface and use it to hang tools, cables, lamps, or other objects. The steel pot concentrates the magnetic force onto the flat front side, making the holding power on steel much higher than that of the same magnet without a pot. You can read more about this principle in Why are pot magnets so strong?
Step 1: choose the type
- Standard hook magnet: steel pot with NiCuNi coating, for dry indoor spaces such as workshops, warehouses, and shops.
- Swivel hook: the hook rotates, ensuring that an object can always hang straight.
- Rubber-coated hook magnet: the rubber casing protects the surface the magnet is attached to and provides grip, preventing it from sliding.
Step 2: choose the holding power
The holding power in the table is measured under ideal conditions on a flat, thick steel plate. In practice, the actual holding power will be lower due to rust, paint, an air gap, or a thin surface. Furthermore, an object hanging from the hook pulls on the magnet at an angle, causing it to release more easily than it would under a perpendicular pull. Therefore, choose with a margin. Holding power is not a permitted working load: do not use a magnet as the sole means of securing heavy loads where a fall could cause injury. Read how holding power is determined.
Quick selection
| Size | Holding power (approx.) | Suitable for |
|---|---|---|
| Ø10 and Ø13 mm | 5.1 to 6.4 kg | Keys, cables, light objects |
| Ø16 mm | 9.3 kg | Lightweight tools, displays |
| Ø20, Ø25 and Ø32 x 7 mm | 16 to 18 kg | Tools, lamps, workshop |
| Ø32 mm | 29 kg | Heavier tools in workshop and warehouse |
| Ø43 and Ø66 mm rubber | 14 to 27 kg | Where grip and surface protection matter |
| Ø40 to Ø50 mm | 47 to 72 kg | Heavy objects on thick steel surfaces |
| Ø88 mm rubber | 55 kg | Heavy objects with rubber grip |
| Ø60 x 18 mm | 96 kg | Very heavy-duty applications |

Safe use
Magnets are not toys and should be kept out of the reach of children. Keep strong magnets away from pacemakers, electronics, and bank cards. Large hook magnets can snap onto steel with great force; keep your fingers clear.
