This N42 Neodymium Countersunk Magnet is ideal for DIY enthusiasts, crafters, and professionals needing secure fixtures. Its key benefit is a powerful magnetic pull in a compact size, allowing it to be fixed with screws for versatility. A caveat is that magnets can be brittle and require careful handling to avoid chipping or shattering.

Each magnet can support a steel weight of up to 6.7kg vertically when in flush contact with a mild steel surface.
You can fix the magnet using a 5mm diameter countersunk screw through the central hole. The screw secures the magnet to non-magnetic materials.
The triple-layer nickel-copper coating provides good corrosion resistance, making them suitable for many environments. However, prolonged exposure to harsh weather conditions may still affect the coating over time.
Yes, if configured with the same pole facing outwards on the countersunk side, they can create a repelling effect.
N42 refers to the grade of the neodymium magnet, indicating its magnetic strength. Higher numbers generally denote stronger magnets.
Store them away from sensitive electronic devices. To prevent them from sticking together forcefully, store them with plastic or cardboard between them, or with opposite poles facing each other.
Absolutely. They are excellent for closing boxes, creating hidden closures for models, or attaching components in dioramas and theatre sets.
Ensure the magnet is in direct, flush contact with a mild steel surface. Check that the steel surface is thick enough to support the magnetic pull. Verify that you are using the correct pole orientation for attraction.
Neodymium magnets are brittle. Handle them carefully, avoiding impact with other magnets or hard surfaces. If chipped, the magnetic strength may be reduced, and the magnet should be replaced if critical for the application.
Ensure you are using a 5mm diameter countersunk screw. The screw head should be designed to sit flush within the countersink hole for a clean finish.
To set up, position the magnet on your non-magnetic surface. Use a 5mm diameter countersunk screw through the central hole to fix it securely. Ensure the screw is appropriate for the material you are attaching it to. These magnets are compatible with any mild steel surface for optimal performance.
Care Instructions: Clean the magnets with a dry or slightly damp cloth. Avoid harsh chemicals or abrasive materials, as these can damage the coating. Keep magnets away from direct heat sources. Due to their strong magnetic field, store them separately or with opposing poles facing each other to prevent them from sticking together. Handle with care, as dropping them can cause them to chip or break.
