Item Code: CUPM1500-750-Q20
These are powerful neodymium magnets housed inside of a steel cup. The cup protects the magnet and also increases the magnets power by redirecting one polarity towards the other side. Attached to the cup there is a threaded stud that will work perfectly with a standard nut or threaded hole.
The maximum pull strength is measured by pulling the magnet directly off of a piece of steel.
