Nickel Plated Mild Steel Disc with 3M Self-Adhesive - 10mm dia x 1mm thick

• 3/8" diameter x 3/64" thick.
• Premium 3M™ self-adhesive with peel away backing on one side.
• Will stick to most hard, flat surfaces to create a magnetic surface.
• Nickel plated to provide resistance against corrosion.

If you are looking to use a magnet then you need a steel surface, or another magnet, to attract to. A magnet will attract to a steel surface in direct contact with equal strength as a magnet to magnet arrangement, therefore, self-adhesive steel discs can sometimes provide a more cost-effective solution. However, it is important to remember that if there is a gap between the two, then a magnet to magnet attraction will be stronger.

These small steel discs are supplied with convenient, strong 3M™self-adhesive on one side which means they can be stuck to almost any hard, flat surface to create a magnetic surface. They are an essential part of any crafting tool kit and are often used by galleries to hang artwork. What's more, because they are just 3/64" thick they are often used to create a magnetic closure on printed products, such as stationery.

Each sheet has a striped north-south polarity on the magnetic face to give a secure grip. To ensure that the grip remains secure, we recommend allowing between 24 to 32 hours for the adhesive to cure.
