The Neodymium Top Hat Magnet (N42) is an essential tool for professional display installers, sign makers, and hobbyists who require a secure, flush-mount magnetic attachment point. Designed with a unique stepped profile, this magnet allows for clean, hidden integration into thin panels and display structures while providing a robust 1kg pull force. While these magnets offer superior holding power for their compact 8mm x 5mm size, users should be aware that the high-strength neodymium material is brittle and requires careful handling to prevent chipping or snapping against metal surfaces.

It can support up to 1kg of steel weight in a vertical pull test when in direct, flush contact with a mild steel surface.
The nickel-copper-nickel coating offers good corrosion resistance, but they are primarily intended for indoor use. Prolonged exposure to moisture may eventually cause oxidation.
The design is intended for push-fit installation. For a permanent hold, use a high-quality industrial adhesive or epoxy.
N42 refers to the magnetic strength grade of the neodymium material, indicating high energy density and resistance to demagnetisation.
No, the strong magnetic field can damage hard drives, credit card magnetic strips, and sensitive electronic components.
Ensure the magnet is in direct contact with flat, mild steel. Ensure there is no paint, plastic, or gap between the magnet and the metal surface.
Neodymium is a brittle sintered material. Always handle carefully and avoid allowing the magnet to snap forcefully against metal surfaces.
