Perfect for DIY sensors

Using these for Arduino sensor projects. The consistency in strength across the batch is excellent. Shipping was fast and the price point is unbeatable compared to local hardware stores.

Exceeded expectations

I needed strong magnets for a custom cabinet latch system. These work flawlessly. The circular shape makes them easy to embed into wood without sharp corners getting in the way.

Best purchase for organizing

I use these to organize my tools on a steel strip in the garage. They hold heavy pliers and wrenches securely. Highly recommend buying the larger diameter if you need serious holding power.

Incredibly strong for the size

I bought these for a workshop project and was surprised by how much weight a small disc can hold. The nickel coating looks sleek and durable. Just be careful when separating them!

Good but brittle

The magnetic strength is as advertised, but I accidentally dropped one on concrete and it shattered. I guess that's typical for neodymium, but just a warning to others to be gentle.

Great value, handle with care

These magnets are perfect for my refrigerator notes and photo displays. They arrived well-packaged in foam to prevent chipping. One star off because they are so strong they pinched my finger once.

5 FAQ

Q: How are these packaged to prevent them from snapping together during shipping?

A: All our magnets are separated by thick foam spacers or individual plastic dividers within a sturdy box to ensure they arrive safely without chipping or cracking.

Q: Are these magnets safe to use near credit cards or phones?

A: Due to their high intensity, we recommend keeping these magnets at least 6 inches away from credit cards, hard drives, pacemakers, and smartphones to prevent data loss or interference.

Q: What is the exact pull force for the 20mm x 3mm size?

A: The 20mm diameter by 3mm thickness magnet has an approximate vertical pull force of 3.5 kg (7.7 lbs) when attached directly to a thick steel plate.

Q: Can these be used outdoors in the rain?

A: While the Ni-Cu-Ni coating offers some corrosion resistance, prolonged exposure to moisture can cause rusting over time. For outdoor use, we suggest applying an additional epoxy sealant.

Q: Do you offer bulk discounts for orders over 500 units?

A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team via the 'Contact Us' page with your specific quantity requirements for a custom quote.
