  •  Description: 
Neodymium magnets with countersunk holes is for mounting magnets in place. The sink hole can fit a screw, nut or bolt to fix the countersunk magnets on the place you want.

Awesotech Magnetics can supply all kinds of countersunk ndfeb magnets. This neodymium ring magnet used to be assemblied with a steel round shell. It can be fastened with a countersunk screw. The steel pot substantially increases the holding power of the magnet, but requires full contact with the opposing part, e.g. a steel plate. Magnets in steel pots don’t have much effect into the distance, i.e. they are not suitable to attract a metal item from a distance, but they are very well suited to hold on to a piece of metal in full contact.
