Neodymium ring magnet Ø20mm x 3mm x Ø3mm/Ø6.7mm countersunk hole (south pole), N45

This neodymium countersunk ring magnet has an outer diameter of 20 mm, a height of 3 mm, and a 3 mm hole with 6.7 mm countersink, making it ideal for screw mounting. The countersunk design allows the screw head to sit flush, enabling a stable and secure installation in a wide range of applications.
Manufactured from N45 grade neodymium, this magnet offers a pull force of approx. 3.7 kg, providing strong holding power for its size. It is axially magnetized, with poles located on the flat circular surfaces, and the countersunk side functioning as the south pole.
For enhanced durability, the magnet features a triple-layer NiCuNi coating (Nickel-Copper-Nickel), which protects against corrosion and surface damage. With a weight of around 6.5 g, this compact but powerful magnet is perfect for mounting, fastening, furniture construction, shopfitting, and industrial assemblies.
