Wherewe offer a wide range of high-quality countersunk magnets that are perfect for various applications requiring powerful magnetic strength. Countersunk magnets, also known as round base, cup, or RB magnets, are specially designed mounting magnets made with neodymium magnets encased in a steel cup with a 90° countersunk hole in the work surface. One key consideration when using countersunk magnets is their fragility. It is important not to overtighten the screws to avoid damaging them. We advise against using a drill for installation. If you require even stronger magnets, we recommend checking out our slot magnets. These magnets are housed in steel channels, offering enhanced protection against breakage.Our countersunk magnets are constructed with N35 neodymium magnets that are coated with three layers of nickel-copper-nickel (Ni-Cu-Ni), providing maximum corrosion and oxidation protection. These magnets have permanent magnetism and remain strong even after decades of use. A small magnet can provide a remarkable pulling force of 66 pounds (30 kilograms), making them incredibly powerful and reliable. The countersunk magnetic disc is made of NdFeB material, coated with three layers of nickel, copper, and nickel to ensure a smooth surface that reduces corrosion and greatly improves the endurance of the magnet. Compared to similar products on the market, our countersunk magnets excel in terms of performance, quality, and appearance. We have taken into account the flaws of previous versions and continuously improved our magnets to meet the highest standards. Furthermore, we offer customizable specifications to cater to your specific needs.☀ These magnets are versatile and can be easily removed without leaving any marks or stains. They are ideal for various applications, including hanging tools/knives, attaching tarps to boats, cars, lawn mowers, motorcycles, bicycles, building materials, and other outdoor, sports, or gardening supplies and equipment. Whether you need to lift, hold, or position indicators, lights, lamps, antennas, furniture, or machinery, our countersunk magnets are the perfect solution.It is important to note that these magnets should not be used by children and are best suited for applications that require great strength in a small size. They are suitable for use in homes, schools, offices, and stores. ☀ At our website, we offer countersunk magnets that are manufactured under the ISO 9001 quality system, ensuring their durability and reliability. Neodymium magnets, the strongest permanent magnet material available today, are used in our products. They come in various shapes, sizes, and grades, making them suitable for a wide range of industrial applications and personal projects.Choose our countersunk magnets for their exceptional performance, durability, and reputation in the market. Experience the power of neodymium magnets and unlock endless possibilities for your mounting needs.
