Neodymium Countersunk Disc Magnets 3/8x1/4 inch (10x6mm) N52 - Circular Magnetic Ring #4 Screw Hole Size Holder Crafts Fastener Latches Door Cabinet Closure Mechanisms - 10 Matched N/S Pairs (20 Pack)

Experience the perfect balance of power, precision, and versatility with our Neodymium Countersunk Ring Magnets. Compact yet remarkably strong, these magnets are ideal for countless uses - from fastening and mounting to crafting, tool storage, and educational experiments. Each piece features a precision-engineered countersunk hole for #4 screws, enabling quick, flush installation on metal, wood, or plastic surfaces. Whether you're creating magnetic fixtures, assembling removable panels, or designing modular organizers, these magnets deliver unmatched stability and control. Constructed from industrial-grade N52 neodymium, they provide exceptional holding strength relative to their size. Their triple-layer Nickel-Copper-Nickel coating ensures lasting protection against corrosion, oxidation, and mechanical wear — ideal for use in garages, workshops, kitchens, or outdoor sheds. Perfect for makers, designers, and engineers alike, these countersunk magnets bring professional precision to creative environments. Use them to secure display stands, magnetic latches, or tool mounts; they maintain a consistent magnetic field and dependable grip, even after repeated use. In classrooms and STEM laboratories, they perform flawlessly for demonstrations of polarity, levitation, and electromagnetic interaction — reliable, repeatable, and visually engaging for hands-on science education. Sold as 10 Matched N/S Pairs (20 magnets total) — each set includes one magnet with the countersunk hole on the north pole and one on the south pole. This pairing allows the creation of stable latches, closures, and reversible connections that simplify assembly and enable creative flexibility across multiple applications. Upgrade your workspace, lab, or DIY setup with these durable, high-strength magnetic fasteners — compact power designed to make your projects more efficient, organized, and precise.
