Key Features
These magnets are made from neodymium (NdFeB), the strongest type of permanent magnet available, with N52 being the highest grade for maximum and performance.
Each piece measures 30mm diameter × 5mm thickness with a 5mm countersunk hole, allowing secure screw fixing into wood, walls, or metal surfaces.
They can deliver impressive pull force, often reaching over 20–30 lbs depending on surface contact and conditions.
Nickel-copper-nickel coating helps resist corrosion and extends lifespan, even in demanding environments.

Why Choose This N52 Countersunk Magnet Set
Unlike standard magnets, these are engineered for structural holding applications, not just light-duty use. The countersunk design allows flush screw mounting, making them ideal for hidden fasteners, cabinet doors, or removable panels. Compared to glue-on magnets, they offer far greater stability and long-term reliability.

Perfect For (Occasions & Uses)
Ideal for woodworking, cabinet latches, tool organization, garage setups, door closures, DIY crafts, industrial use, and hidden mounting systems. Also great for creative builds requiring strong, invisible fastening.

How to Use
Align the magnet with a pre-drilled hole and secure it using a flat-head screw. Pair with another magnet or steel surface for maximum holding strength.

Care & Safety
Handle carefully, as strong magnets can snap together with force. Keep away from electronics, children, and pacemakers. Avoid dropping, as neodymium magnets can be brittle.
