Ferrite Shallow Pot Magnets

120° maximum operating temperature,Excellent resistance to corrosion,Mild steel pot with zinc plated body,Through Hole Mounting Ferrite Shallow Pot Magnet,The through hole mounting pot magnet is a pot magnet that has a hole in the centre of the ferromagnetic mild steel cup and a ring magnet inserted inside the cup.The ring magnet inner diameter is larger than the cup central hole size. This allows screws (ideally cap head screws but countersunk screws could also be used) and bolts to be inserted inside the pot magnet to securely mechanically hold the through hole mounting pot magnet in place.The Advantages of Through Hole Mounting Shallow Pot Magnets.The advantage of the through hole mounting pot magnet over a countersunk pot magnet (shallow pot magnet) is that the screw or bolt is tightened onto the steel case so can be as tight as the steel and threads will allow. The disadvantage of the through hole mounting pot magnet over a countersunk pot magnet (shallow pot magnet) is that the magnet is not held securely (the magnet is glued in place and should be securely held in during normal usage - the countersunk/shallow pot magnet has the screw head mechanically assisting with holding the magnet securely in place; please note that it is extremely unlikely that the magnet would ever come away from the adhesive during typical normal usage).
