Screw-Fixed Magnetic Attachment Points
Create a tidy magnetic holding point on a suitable surface. Each compact disc has a countersunk center hole so the included screw can sit inside the face instead of blocking contact with a compatible ferromagnetic item.
Why You’ll Love It
Simple Screw-On Installation
Mark the position, confirm the surface and fastener are suitable, then drive the screw through the recessed center without overtightening the brittle magnet.
Separate the Stack with Control
Slide one disc sideways from the top, tilt it away, and then lift it free to reduce sudden snapping and pinched fingers.
Flexible Home and Workshop Uses
Build magnetic holding points for compatible utensils, tools, notes, or other lightweight items after confirming surface strength and safe placement.
Where It Fits into Real Life
• Organize compatible metal tools on a suitable workshop surface.
• Create a fixed magnetic point for notes or lightweight accessories.
• Add removable holding points to a cabinet, bench, or project panel where drilling is appropriate.
Scene props shown in the gallery are not included, and each installation must be assessed for its actual surface and load.
How to Use
- Keep the magnets away from children, pets, pacemakers, electronics, and items that can be damaged by strong magnetic fields.
- Confirm that the mounting surface, included screw, and item to be held are compatible.
- Separate one magnet by sliding it sideways from the stack; do not let the discs slam together.
- Mark the mounting point, drill a pilot hole when appropriate, and fasten through the countersunk center without overtightening.
- Test the installed magnet with a light item first and inspect the screw and surface regularly.
A Closer Look
The set contains ten matching disc magnets and screws. The recessed opening helps the screw head sit within the magnet face for closer contact with a compatible ferromagnetic object.

Frequently Asked Questions
Will these magnets hold to every metal?
No. They require a compatible ferromagnetic item; aluminum and many grades of stainless steel are not magnetic.
How should I separate the magnets?
Slide one disc sideways from the top of the stack, tilt it away, and then lift it free. Keep fingers clear as the discs can snap together.
Can I use them for safety-critical or overhead loads?
No. Do not use them for lifting people, safety support, or any overhead application where failure could cause injury or damage.
What if a magnet is swallowed?
Seek urgent medical help immediately. Swallowed magnets can cause severe internal injury.
