This high strength cup magnet is made of a neodymium magnet encased inside a chrome plated steel cup. This design greatly increases the holding power of the magnet, as well as protects the magnet from shattering or damage from everyday use, allowing it to last much longer than a plain magnet. This magnet holds up to 95 lbs when held against steel surfaces when the magnet has direct contact with a smooth plain steel surface. The countersunk hole is meant for a #10 flat head screw to ensure a flush fit with the cup magnet. This magnet measures 1.26” in diameter and is 0.2” thick.
