About this item

The K800 Round Super Circular Magnet is a compact yet potent neodymium (NdFeB) ring magnet defined by its 12 mm outer diameter, 4 mm inner diameter, and 4 mm thickness—dimensions roughly 11.8 × 3.74 mm. Its axial magnetization and small form make it remarkably strong, ideal for demanding miniature applications. Constructed with a protective coating for enhanced corrosion resistance, this lightweight, silver-hued magnet offers exceptional holding power relative to its size. Common deployment areas include corrective devices and dental solutions—such as securing dentures when several teeth are missing—where even tiny magnets must perform reliably. Thanks to their size and strength, these magnets are also trusted in engineering quick-release attachments, model assembly, and compact fixtures requiring high-performance magnetism in confined spaces. Despite their power, the K800 magnet maintains a user-friendly design, easily handled and precisely positioned. Each magnet comes with a standard supplier warranty covering manufacturing defects during a 15-day period post-delivery. Overall, the K800 represents a powerful, versatile solution for any project needing a small yet strong magnetic coupling—offering precision, durability, and flexibility in one neat package.
