Product Description

20mm x 6mm Ring Countersunk Neodymium Magnets N52
Countersunk descending diameter 8.5mm-3.5mm.

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.

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.
