You are currently in our 12mm (0.47") diameter countersunk magnet section. Countersunk magnets are ideal for many DIY and home improvement projects as they can be quickly and easily fixed in position using a countersunk screw. The magnets in this section are made from high grade N42 neodymium which is a super-strong magnetic material but also quite brittle. A top tip for using countersunk magnets is to use a forstner drill bit to recess the magnets so they are protected from continuous impact, prolonging the life of the magnet.
