Hook magnets are integrated magnetic tools combining a strong magnet base with a durable hook, designed to hang objects securely on ferrous surfaces. The magnet base—usually made of neodymium (for high strength) or ferrite (for cost-effectiveness)—delivers the holding force, while the hook (often steel or plastic-coated steel) provides a stable point to hang items. They come in various designs, from small, compact models for lightweight use to heavy-duty versions with reinforced hooks for larger loads.

Common applications include home organization: hanging keys, kitchen utensils, or towels on refrigerator doors or metal cabinets. In workshops, they hold tools like pliers, wrenches, or measuring tapes on toolboxes or metal workbenches, keeping items accessible. They also serve in retail, where lightweight signage or promotional materials are hung on metal display racks.

A key benefit is portability—no drilling or mounting hardware is needed, making them easy to reposition. Weight capacity varies: small hook magnets (20mm diameter) hold 1–3 kg, while heavy-duty ones (50mm diameter) can support 10–15 kg. Users should note that holding force decreases with uneven surfaces or non-ferrous materials (e.g., aluminum). Additionally, plastic-coated hooks prevent scratches on delicate items, making hook magnets a practical, damage-free hanging solution for diverse scenarios.
