N48 Neodymium Round Disc Magnets 1/2 x 1/16 inch (12x1.5mm) – Strong Rare Earth Circular Disk Magnet for Crafts, Needle Minders, 3D Prints, Fridge (50 Pack)

These N48 neodymium disc magnets are built for makers who need strong hold without added height. At just 1/16 inch (1.5mm) thin and 1/2 inch (12mm) in diameter — about the size of a shirt button — each disc drops cleanly into shallow craft recesses, 3D-printed magnet seats, and needle minder backs, sitting completely flush with the surface.The N48 rare earth grade delivers up to 3.5 lbs of pull force: strong enough to hold a needle minder securely through multiple layers of stitching fabric, keep notes and maps flat on a steel fridge door, or fasten a lightweight magnetic closure on a handmade box or bag. The NiCuNi coating gives each disc a smooth finish that won't scratch whiteboard surfaces or refrigerator panels.Each magnet is axially magnetized through its thickness — place one disc on the front of your needle minder and one against the back of the fabric, and they grip through the cloth without marking the threads. For 3D printing, the 12x1.5mm dimensions fit standard shallow magnet seat designs. For EVA foam cosplay builds, these discs embed cleanly in routed channels for low-profile panel closures. These permanent rare earth discs are rated for a maximum operating temperature of 80°C (176°F), making them suitable for indoor workshop and classroom fixture applications.At N48 grade, the magnetic flux is strong relative to the disc footprint — the thin profile does not reduce face-to-face grip when poles are aligned. Fifty discs per pack provide enough for a full needle minder production run or a complete set of fridge display projects.SAFETY: Strong magnets can pinch skin. If swallowed, magnets can cause serious internal injury — keep away from children. Keep away from pacemakers and electronic devices. Not suitable for children under 14.
