Strong Magnet 30 x 3 mm 8 KG pull Neodymium discs 🧲

This set of compact neodymium disc magnets delivers strong holding power in a small package, useful for home organisation and light workshop work. With a 30 x 3 mm size and an 8 kg pull rating each, these magnets are handy for attaching photos, spice jars and tools to metal surfaces while keeping a low profile.

Key Points

The magnets feature a nickel-copper-nickel (Ni-Cu-Ni) coating that gives a smooth, silver finish and helps resist corrosion. They are made from rare earth neodymium, a material known for high magnetic strength relative to size, so a small disc can support items that larger ferrite magnets would struggle with. These discs come in a pack of four, which makes them practical for multiple uses around the house, office or classroom. ⚙️

Although powerful, take care when handling near electronics or credit cards because strong magnetic fields can interfere with some devices. Also consider that the protective coating may be compromised if the magnets are struck together repeatedly, and that could affect corrosion resistance over time. 🔧

Usage Recommendations

Place these magnets on clean, flat metal surfaces for the best grip. For craft projects, embed them into wooden or plastic housings using strong adhesive or double-sided tape, and allow the adhesive to cure fully before loading heavy items. For fridge use and light organising, position one magnet per item initially and test the hold, adding more discs if needed for larger or heavier objects. 🧲

When storing or transporting the discs, keep them separated with spacers or inside individual compartments to prevent them snapping together and chipping the coating. For safety, keep them away from children and pets, and avoid letting fingers get trapped between two strong magnets as this can cause painful pinches or skin damage.

Positive Aspects

The low-profile 3 mm thickness blends discreetly into many setups while still providing a surprisingly strong magnetic hold. Their smooth metallic finish looks neat on visible surfaces, and the compact size makes them versatile for creative mounting solutions in DIY projects and classroom demonstrations. Additionally, having four identical discs gives flexibility to distribute holding points evenly across an item for a more secure attachment.
