Recessed metal plate 12x12x3 mm.

Square metal piece with recessed hole for hanging. Used as a counterpart to a magnet. 

Not a magnet!

The magnetic metal plates are not magnets in themselves - they are magnetic and are used together with e.g. power magnets.

SPECIFICATIONS:
Size: 12 x 12 mm.
Height: 0.3 cm.
Screw hole: ø 5.7 mm.

The metal pieces are not suitable for outdoor use (will rust over time).

Fits with power magnets that have a size equivalent to 12x12 mm.

Mounting:

When fixing the metal plate, it is best to use a countersunk screw with a conical head - 4.7 mm. to 5.7 mm. can be used. 

If the metal plate is to be mounted in thin wooden walls (e.g. a wardrobe), the screws can be bought in most hardware stores. You often find them in screw assortment boxes. 

Alternatively, you can use a longer screw with a head size of approx. 5 mm. and shorten it in length with a bias bit or similar.
