39 LB Cup Magnet w/ #10 Countersunk Hole 1" Diameter Neodymium Cup Magnet Black Epoxy Coated
This neodymium cup magnet is made of a super strong neodymium magnet encased inside a steel cup. The neodymium magnet is bonded inside of the cup with adhesive. This magnet and cup forms a magnetic circuit which triples the holding force to 39 lbs and the steel cup also protects the magnet from breaking. The epoxy coating also provides a better protection for the magnet from rusting than the nickel coating.
The applications of this round base magnet include magnet holding, closing, Mounting, retrieving and much more.
Most powerful little magnet. Used magnets (2) to hold large Bowie knife to inside of a “shadow box” to secure knife. So pleased!!
