12 pieces Neodymium Magnets 10 KG Force 20 x 7 mm with Hole and Capsule, Countersunk Pot Magnet with Screw and 12 Steel Pads (Piano Black)

[Item in package] 12 x recessed pot magnets, size 20 x 7 mm, 12 x steel pads, size 20 x 2 mm, 24 x M4 screws.
[Powerful magnets] The maximum pulling force of the magnet is over 12 kg. Each magnet can generate a vertical suction of 10 kg on the sheet metal inside the package.
[12 recessed steel pads included] The steel pads can be nailed to the object the magnet is to attract, creating a magnetic door effect.
[Rust and water resistant] The surface is coated with 4 layers of nickel-copper-nickel plus automotive-grade epoxy for a total salt spray test of over 72 hours. This effectively solves the problem of neodymium magnets rusting. Ideal for outdoor use.
[We adhere to material standards] We insist on not using low-quality magnets with low coercivity and reduced neodymium content.
