permanent Ndfeb pot magnet with external threaded mounting
1.This Neodymium or ferrite ring magnet in a steel pot is countersunk.It can be fastened with a countersunk screw.The steel pot substantially increases the holding 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 item from a distance,but they are very well suited to hold on to a pieceof metal in full contact.
2.This magnetic hook also handy in office on filing cabinets,supershop or in School and so on.
3.The holding force is vary from 3kgs to 30kgs.Or according to customer's request,we can design and proceed with different size magnetic hook
4.The quality control:we have our large and expert quality control department and we ensure the magnets from our factory are in high quality.
