This round base neodymium magnet has 112 lb holding power. The thread is #1/4-20.
This neodymium round base magnet is made of a super strong neodymium magnet encased in 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 112 lbs! At the same time, the steel cup also protects the magnet from being damaged when it's frequently used.
The holding power of 112 lbs is when the cup directly contacts with the steel. The outer diameter of the magnet is 1.57" (40mm). The mounting hole in the center is 0.216" (5.5mm) which allows a #10 screw pass through. The total thickness of the assembly is 0.32" (8mm).
The applications of this cup magnet include magnetic holdings, lifting, antenna Mounting, positioning, retrieving and much more.
The round base magnet is also known as magnetic cup holders.
