N52 Grade Neodymium Ring Countersunk Strong Magnet D20mm

N52 Grade Neodymium Ring Countersunk Strong Magnet D20mm x 6mm

These large sized facing pair of countersunk neodymium magnets are perfect for any carpentry or home improvement projects.

The specially designed countersunk hole enables the convenient use of flat head screws to fasten it to any flat or recessed area.

Be careful if using ferrous metal screws with these countersunk magnets.
Once the screw are inserted into the hole, it will be extremely painful if your finger were to get caught between the pointed screw and another magnet or metal.
Alternative is to use stainless steel screws.
Do not use high power driver to fasten the screws as over tightening might damage or break the countersunk magnet.

Because of the facing pair polarity, it works even if you:
a) secure each of the magnet on 2 separate objects such that it can be magnetically attached or detached
b) you secure both pieces of magnets on a single object and magnetically attach it to metal surfaces.
