Neodymium pot magnets (also called mounting magnets, or cup magnets) with countersunk holes are designed for screws to be used for permanent positioning, leaving the screw head flush with the magnet. These high strength rare earth magnets have a mild steel cap for extra protection against chipping or cracking. Due to the protective cover on these pot magnets, they are single sided magnets which provide an easy, non-destructive solution for attaching and suspending objects.
Due to the versatility and high quality of our rare earth pot countersunk magnets they can be used for different applications and also for household or industrial uses. This 50.8 mm pot magnet can be used for construction, building or design purposes.
If you are looking for a pot magnet designed for flat screws or bolts, take a look at our Straight Center Hole Pot Magnets. Neodymium Pot Magnet with Counterbore, Pot Cap Neodymium Magnet Φ60mm with M8 Countersunk Screw
Becase of being used strong Neodymium Magnet , Neodymium Pot Magnet is a feature of strongest holding force with smallest volume when it is compared with other Magnetic pot.Mag Spring provide comprehensive strong holding solution by developing total thirteen standard series of Neodymium magnetic pots.Accroding to different application situation,these magnetic pots include hook magnet series, countersunk pot magnets searies,screw magnet,etc.Special magnetic pot items are also available according to custom requirement.Base on using strong rare earth magnets, magnetic pot also named heavy duty magnet.In some applications ,they also can be called magnet holds, magnetic ceiling hook,etc. Ø50mm Neodymium Holding Pot Magnet with Countersink Bore / Counterbore
Special feature: The magnet has a central hole with a counter bore. This allows the holding magnet to be securely screwed to the wall / ceiling using a countersunk screw. Metallic counterparts then adhere magnetically to this pot magnet. The maximum operating temperature is 80 ° C.
The holding magnets / assembly magnets / pot magnets are used particularly often in industry, trade fairs and assembly. The strong pot magnets are also indispensable in the advertising sector / display construction / lighting sector.
