Our magnet base is made of high-quality materials. It is strong, rust-resistant, wear-resistant, and precisely manufactured for reliable performance in various applications. You will receive 24 or 12 mounting magnets, each measuring approximately 1.69 inches (43 mm) in diameter and 0.24 inches (6 mm) in height, with M6 x 0.4 screws (10 mm thread length), suitable for mounting lamps, whiteboards, and other items. The rubber-coated surface helps protect the magnetic strength and provides durability against breakage or deformation during normal use, extending the magnet’s service life. The smooth surface also helps prevent scratching mounted objects. The magnet features a countersunk center hole design, optimized for secure screw installation. Screws are included for easy mounting. This stud magnet is ideal for securing work lights, vehicle lighting strips, display panels, automated equipment, tools, machinery, calendars, maps, signage, and dry-erase boards. It is commonly used in homes, warehouses, garages, workshops, offices, classrooms, and schools.
