This cup neodymium magnet has 23 lb holding power. The countersunk hole is for #8 screw.

This neodymium round base magnet is made of a super strong neodymium magnet encased inside a chrome plated steel cup. The neodymium magnet is bonded inside of the cup with adhesives. This design forms a magnetic circuit which triples the holding force to 23 lbs! At the same time, the steel cup also protects the magnet from being damaged when frequently used. The counter sunk hole on the magnet is provided for easy applications. A #8 screw will fit to the countersunk.
The applications of this round base magnet include magnetic holding, lifting, antenna Mounting, positioning, retrieving and much more.
The round base magnets are also known as magnetic cup holders or magnetic cup assembly.

This stainless steel mounting magnet is a new, water resistant design available exclusively at UMAGNETS.COM. It allows neodymium mounting magnets to be used in wet environments, where occasional contact with moisture is expected.

Most of our other Mounting Magnets are made with nickel plated magnets that are exposed, with a nickel plated steel cup that the magnet sits in. In outdoor use where magnets can occasionally get wet, both the magnet and the steel cup can corrode or rust. The exposed portions of this sealed magnet are all stainless steel, which protects the internal magnet from corrosion.
