ECLIPSE MAGNETICS E770NEO/F 钕磁铁, 薄型, 6X4.5MM, M3
The is a neodymium Shallow Pot Magnet with thread hole. The internal threaded stud pot magnet is also known as a female threaded stud pot magnet. They consist of a ferromagnetic mild steel cup containing a magnet usually a disc magnet with a ferromagnetic mild steel stud/boss/bush mounting at the back of the pot magnet into which a threaded hole has been made. These neodymium pot magnets are known as female threaded stud pot magnets because the internal threaded hole could take pot magnets with threaded bar at the back external threaded stud pot magnets/male threaded stud pot magnets as well as bolts. Because the mild steel is stud/boss is threaded there is decent thread length allowing reasonably high torque to be applied to securely hold each pot magnet in place.
